Life Tech Becomes Partner in Saudi Human Genome Program, International Barcode of Life Project

December 09, 2013

NEW YORK, GenomeWeb − Life Technologies has become a partner in two research projects, the Saudi Human Genome Program and the International Barcode of Life (iBOL) project, the company said this week. The projects will employ the firm’s Ion Proton, capillary electrophoresis, and PGM sequencing technologies.

The goal of the Saudi Human Genome Project, led by Saudi Arabia’s national funding agency, the King Abdulaziz City for Science and Technology (KACST), is to study the genetic basis of disease in Saudi Arabia and the Middle East.

Over the next five years, the project aims to sequence 100,000 genomes from individuals from the region using Life Tech’s Ion Proton technology. Sequencing will be initially conducted at 10 genome centers across Saudi Arabia, with five additional centers to be created in the future.

Life Tech will design and equip the centers, and provide “end-to-end solutions” and services for operations and informatics. Integrated Gulf Biosystems, Life Tech’s distributor in the Middle East, said it played a “pivotal role” in bringing Life Tech’s technology to KACST.

Results from the project will be used to build a Saudi-specific database, providing the basis for future personalized medicine in the Kingdom. Specifically, the information is expected to help with premarital and prenatal screening for rare genetic diseases, as well as for population studies.

Searchable Genome for Drug Development

Reporter: Aviva Lev-Ari, PhD, RN

The Druggable Genome Is Now Googleable

By Aaron Krol

November 22, 2013 | Relationships between human genetic variation and drug responses are being documented at an accelerating rate, and have become some of the most promising avenues of research for understanding the molecular pathways of diseases and pharmaceuticals alike. Drug-gene interactions are a cornerstone of personalized medicine, and learning about the drugs that mediate gene expression can point the way toward new therapeutics with more targeted effects, or novel disease targets for existing drugs. So it may seem surprising that, until October of this year, a researcher interested in pharmacogenetics generally needed the help of a dedicated bioinformatician just to access the known background on a gene’s drug associations.

Obi and Malachi Griffith are particularly dedicated bioinformaticians, who specialize in applying data analytics to cancer research, a rich field for drug-gene information. Like many professionals in their budding field, the Griffiths pursued doctoral research in bioinformatics applications at a time when this was not quite recognized as a distinct discipline, and quickly found their data-mining talents in hot demand. “We found ourselves answering the same questions over and over again,” says Malachi. “A clinician or researcher, who perhaps wasn’t a bioinformatician, would have a list of genes, and would ask, ‘Well, which of these genes are kinases? Which of these genes has a known drug or is potentially druggable?’ And we would spend time writing custom scripts and doing ad hocanalyses, and eventually decided that you really shouldn’t need a bioinformatics expert to answer this question for you.”

The Griffiths – identical twin brothers, though Malachi helpfully sports a beard – had by this time joined each other at one of the world’s premiere genomic research centers, the Genome Institute at Washington University in St. Louis, and figured they had the resources to improve this state of affairs. The Genome Institute is generously funded by the NIH and was a major contributor to the Human Genome Project; the Griffiths had congregated there deliberately after completing post-doctoral fellowships at the Lawrence Berkeley National Laboratory in California (Obi) and the Michael Smith Genome Sciences Centre in Vancouver (Malachi). “When we finished our PhDs, we knew we would like to set up a lab together,” says Obi. At the Genome Institute, they pitched the idea of building a free, searchable online database of drug-gene associations, and soon the Drug Gene Interaction Database (DGIdb) was under development.

In Search of the Druggable Genome

Existing public databases, like DrugBank, the Therapeutic Target Database, and PharmGKB, were the first ports of call, where a wealth of information was waiting to be re-aggregated in a searchable format. “For their use cases [these databases] are quite powerful,” says Obi. “They were just missing that final component, which is user accessibility for the non-informatics expert.” Getting all this data into DGIdb was and remains the most labor-intensive part of the project. At least two steps removed from the original sources establishing each interaction, the Griffiths felt they had to reexamine each data point, tracing it back to publication and scrutinizing its reliability. “It’s sort of become a rite of passage in our group,” says Malachi. “When new people join the lab, they have to really dig into this resource, learn what it’s all about, and then contribute some of their time toward manual curation.”

The website’s main innovation, however, is its user interface, which presents itself like Google but returns results a little more like a good medical records system. The homepage lets you enter a gene or panel of genes into a search box, and if desired, add a few basic filters. Entering search terms brings up a chart that quickly summarizes any known drug interactions, which can then be further filtered or tracked back to the original sources. The emphasis is not on a detailed breakdown of publications or molecular behavior, but on immediately viewing which drugs affect a given gene’s expression and how. “We did try to place quite a bit of emphasis on creating something that was intuitive and easy to use,” says Malachi. Beta testing involved watching unfamiliar users navigate the website and taking notes on how they interacted with the platform.

DGIdb went live in February of this year, followed by a publication in Nature Methods this October, and the database is now readily accessible at http://dgidb.org/. The code is open source and can be modified for any specific use case, using the Perl, Ruby, Shell, or Python programming languages, and the Genome Institute has also made available their internal API for users who want to run documents through the database automatically, or perform more sophisticated search functions. User response will be key to sustaining and expanding the project, and the Griffiths are looking forward to an update that draws on outside researchers’ knowledge. “A lot of this information [on drug-gene interactions] really resides in the minds of experts,” says Malachi, “and isn’t in a form that we can easily aggregate it from… We’re really motivated to have a crowdsourcing element, so that we can start to harness all of that information.” In the meantime, the bright orange “Feedback” button on every page of the site is being bombarded with requests to add specific interactions to the database.

Not all these interactions are easy to validate. “Another area that we’re really actively trying to pursue,” adds Malachi, “is getting information out of sources where text mining is required, where information is really not in a form where the interaction between genes and drugs is laid out quickly.” He cites the example of clinicaltrials.gov, where the results of all registered clinical trials in the United States are made available online. This surely includes untapped material on drug-gene interactions, but nowhere are those results neatly summarized. “You either have a huge manual curation problem on your hands – there’s literally hundreds of thousands of clinical trial records – or you have to come up with some kind of machine learning, text-mining approach.” So far, the Genome Institute has been limited to manual curation for this kind of scenario, but with a resource as large as the clinical trials registry, the Griffiths hope to bring their programming savvy to bear on a more efficient attack.

In the meantime, new resources are continuously being brought into the database, rising from eleven data sources on launch to sixteen now, with more in the curation pipeline. DGIdb is already regularly incorporated in the Genome Institute’s research. Every cancer patient sequenced at Washington University has her genetic data run first through an analytics pipeline to find genes with unusual variants or levels of expression, and then through DGIdb to see whether any of these genes are known to be druggable. This is an ideal use case for the database, which is presently biased toward cancer-related interactions, the Griffiths’ own area of research.

The twins have a personal investment in advancing cancer therapeutics. Their mother died in her forties from an aggressive case of breast cancer, while Obi and Malachi were still in high school, and their family has continued to suffer disproportionately from cancer ever since. Says Obi, “We’ve had the opportunity to see [everything from] terrible, tragic outcomes… to the other end of the spectrum, where advances in the way cancer is treated were able to really make a huge difference to both our cousin and our brother,” both in remission after life-threatening cases of childhood leukemia and Ewing’s sarcoma, respectively. “Everyone can tell these stories,” Malachi adds, “but we’ve had a little more than our fair share.”

DGIdb can’t influence cancer care directly – most of the data available on drug-gene interactions is too tentative for clinical use – but it can spur research into more personalized treatments for genetically distinct cancers, and increasingly for other diseases as more information is brought inside. Meanwhile, companies like Foundation Medicine and MolecularHealth are drawing on similar drug-gene datasets, narrowed down to the most actionable information, to tailor clinical action to individual cancer patients. The Griffiths are cautiously optimistic that research like the Genome Institute’s is approaching the crucial tipping point where finely tuned clinical decisions could be made based on a patient’s genetic profile. “We’re still firmly on the academic research side,” says Malachi, but “we’re definitely at the stage where this idea needs to be pursued aggressively.”

Biology Professor Eric S. Lander of the Eli and Edythe Broad Institute of the Massachusetts Institute of Technology and Harvard University, and Eli Yablonovitch, Professor of Electrical Engineering and Computer Science at the University of California, Berkeley, were awarded the 2012 Harvey Prize in a ceremony April 30 at the Technion-Israel Institute of Technology in Haifa, Israel.

The awarding of the Harvey Prize is watched closely worldwide, as it is often regarded as a strong predictor of future Nobel Prize laureates. The international prize is awarded annually by the Technion in a variety of disciplines within the categories of Science and Technology and Human Health. It has also been awarded for contributions to Peace in the Middle East.

Prof. Lander, the founding director of the Broad Institute and one of the principal leaders of the Human Genome Project, received the award in the area of Human Health for his contributions to the field of genomics. Calling Prof. Lander a “driving force behind most of the major advances in this field,” the citation for the prize read: “He has made important contributions by both developing methods to exploit the power of genetic information and leading large endeavors to identify and annotate entire genomes. Most notably, he consolidated the efforts of the Human Genome Project and first authored the resulting historic manuscript. Prof. Lander also pioneered the analysis of the genetic components underlying complex diseases, including cancer.”

In accepting his award, Prof. Lander credited his success to a series of “lucky accidents,” including a chance meeting with Princeton University Professor David Botstein, who invited Prof. Lander to work with him on mapping diseases. “I had no inkling of what was yet to come. But the idea of the Human Genome Project was in the air.” He recounted an unlikely career, in which he studied mathematics and taught business before discovering the sense of “shared purpose” in working collaboratively on a larger project.

Prof. Lander, who is the Professor of Biology at MIT and Professor of Systems Biology at Harvard Medical School, has received numerous awards including the MacArthur Foundation Fellowship, the Gairdner Foundation International Award, the Max Delbruck Medal, the American Association for the Advancement of Science’s Award for Public Understanding of Science and Technology, among others, and eight honorary doctorates. In 2009, President Obama appointed him to co-chair the President’s Council of Advisors on Science and Technology.

Prof. Yablonovitch, the Director of the National Science Foundation Center for Energy Efficient Electronics Science at UC Berkeley, received the award in the area of Science and Technology in recognition of “his pioneering discoveries in the fields of photonics, optoelectronics and semiconductors.” In his photovoltaic research, Prof. Yablonovitch introduced the 4n2 light-trapping factor that is in worldwide use for almost all commercial solar panels. This factor, sometimes called the “Yablonovitch Limit” increased the theoretical limits and practical efficiency of solar cells. Prof. Yablonovitch is also regarded as the Father of the Photonic BandGap concept, and as having coined the term “Photonic Crystal.”

In accepting his award Prof. Yablonovitch, who holds the James & Katherine Lau Chair in Engineering, credited Israel for its success in educating young scientists. But he noted that Israel should provide job opportunities for “graduates to further develop their scientific potential” post-graduate school, as he was able to do at Bell Laboratories.

Prof. Yablonovitch has received numerous awards including the Institute of Electrical and Electronics Engineers’ (IEEE) Photonics Award, The Institution of Engineering and Technology’s Mountbatten Medal, the Julius Springer Prize, the R.W. Wood Prize, the W. Streifer Scientific Achievement Award, and the Adolf Lomb Medal. He holds two honorary doctorates, is a Fellow of the IEEE, and a member of both the National Academy of Sciences and the American Academy of Arts & Sciences.

The Harvey Prize was first awarded in 1972 from a fund established by the late Leo M. Harvey, and maintained by his son, Technion Guardian Homer Harvey and the Harvey Family of Los Angeles. Some 13 Harvey Prize recipients have also been awarded the Nobel Prize including former Soviet Union leader Mikhail Gorbachev, and Israelis Robert Aumann and Ada Yonath.

10 Years On, Still Much To Be Learned From Human Genome Map

Advances made in genetics of disease, but creating new drugs more complex than first thought

By Amanda Gardner
HealthDay Reporter

FRIDAY, April 12 (HealthDay News) — As scientists mark the 10th anniversary Sunday of the completion of the Human Genome Project, they will note how that watershed effort has led to the discovery of the genetic underpinnings of almost 5,000 diseases.

And it has made it possible to develop personalized treatments that have prolonged the lives of many.

But the scientists will also acknowledge that, while the project has unlocked many mysteries that once shrouded diseases, there’s still much to be learned before new drugs can be developed to target illness-causing mutations in human DNA.

“What we’ve learned over the past 10 years is that we’re still far from really understanding the complexity of the human genome,” said Eric Schadt, chairman of genetics and genomic sciences at Mount Sinai Icahn School of Medicine in New York City. “Human disease is way more complicated than the old view that single hits to single genes cause diseases.

“In most forms of diseases, it’s whole constellations of genes operating in networks,” Schadt explained. “That becomes a much harder problem. How do you target networks with a single drug?

“We keep learning how much we really don’t know and how much further we need to go,” he added. “That’s the big story.”

A decade ago, the Human Genome Project was hailed as a major milestone because researchers identified all of the nearly 25,000 genes in human DNA and sequenced the 3 billion chemical base pairs comprising that DNA.

The feat took 13 years and cost close to $3 billion, but the genetic information gleaned from the project gave scientists the tools needed to pinpoint how changes in specific genes could kick-start some diseases.

One of the most tangible benefits of the project has been the development of ever more sophisticated sequencing technology and a dramatic lowering of the cost of using that technology.

Today, the cost of sequencing one human genome is closer to $5,000 and can be done in a day or two, said Dr. Eric Green, director of the National Human Genome Research Institute in Bethesda, Md.

What that means is that the pace of research, and its attendant discoveries, has been accelerated.

When the project first began, scientists knew the genetic basis of about 53 diseases. Today, that number is close to 5,000, Green noted. That means doctors can now test patients to see if they carry gene mutations that raise their risk for certain diseases, and counsel them accordingly on ways they might prevent or delay illness. There are currently almost 2,000 genetic tests for specific diseases or conditions, according to the U.S. National Institutes of Health.

There have also been breakthroughs with some rare diseases.

In 2011, 6-year-old Nicholas Volker became the first child to be saved by the new technology. He had undergone a hundred surgeries, including the removal of his colon, as doctors tried to identify his mysterious bowel disease. Genomic sequencing uncovered a genetic mutation that could be treated with a bone marrow transplant consisting of cells from umbilical cord blood.

“Knowing more of the basic genetics that makes up an individual has allowed us to diagnose far more genetic diseases,” said Dr. Barbara Pober, a medical geneticist at the Frank H. Netter, M.D. School of Medicine at Quinnipiac University in North Haven, Conn.

Once a diagnosis has been made, doctors can now use gene sequencing to determine treatment for some diseases. For instance, breast cancer patients can be tested to see how they will respond to the drug Herceptin. HIV patients can be tested to determine their response to the drug abacavir. And those on the widely used blood thinner warfarin can be tested to determine the most effective dose, according to the NIH.

The field of pharmacogenetics, still in its infancy, enables doctors to use a patient’s genetic information to figure out which cancer drugs the patient will best respond to before treatment even starts.

The U.S. Food and Drug Administration now includes genetic information on labeling for more than 100 drugs, up from just four 10 years ago, Green said.

The goal of developing new drugs to target diseases with genetic roots, however, will take much longer to realize.

Although the NIH states that there are roughly 350 biotechnological products currently being tested in clinical trials, new drugs take a decade or more to develop. Not only that, the knowledge gained from the Human Genome Project has actually made the field of genetic medicine even more complex. Scientists are finding that many diseases are triggered by interaction involving multiple gene variants, making it difficult to design a treatment that targets all the culprits in a particular illness.

And the complexities don’t end there.

Not long ago, scientists discovered that so-called “junk” DNA, which makes up 98 percent of the genome, is not junk at all but serves critical regulatory functions.

What’s more, about 10 percent of the human genome still hasn’t been sequenced and can’t be sequenced by existing technology, Green added. “There are parts of the genome we didn’t know existed back when the genome was completed,” he said.

Centers of Excellence in Genomic Sciences (CEGS): NHGRI to Fund New Center (CEGS) on the Brain: Mental Disorders and the Nervous System

April 16, 2013

NEW YORK (GenomeWeb News) – The National Human Genome Research Institute plans to fund new Centers of Excellence in Genomic Sciences, or CEGS, to create interdisciplinary teams that pursue innovative genome-based approaches to address biomedical problems and to understanding the basis of biological systems.

NHGRI, along with support from the National Institute of Mental Health, expects to provide up to $2 million per year for each of the new CEGS it funds, and plans to award up to four new awards each year.

Although these CEGS may pursue a wide range of research objectives, NIMH will support the program because it wants to fund research using novel genomic approaches that can accelerate the understanding of the genetic basis of mental disorders and the nervous systemNHGRI said on Friday.

The CEGS program was created to use the new knowledge and technologies that resulted from the Human Genome Project and subsequent genomics research to develop new tools, methods, and concepts that apply to human biology and disease.
CEGS grantees are expected to be innovative, to focus on a critical issue in genomic science, to use multiple investigators working under one leader, to work toward a specific outcome, and to tackle challenging aspects of problems that may have impeded previous research efforts.

Further, they are supposed to bolster the pool of professional scientists and engineers who are trained in genomics through offering educational programs, and they are expected to address the shortage of scientists from underrepresented minority communities by developing recruiting programs that encourage minority community members to become independent genomics investigators.

The technologies and methods the CEGS investigators develop should be applicable to a wide range of cell types and organisms, and they should be scalable and expandable so they may apply to other model systems, according to NHGRI’s funding opportunity announcement.

Recent CEGS centers include

  • Caltech’s Center for In Toto Genomic Analysis of Vertebrate Development;
  • Harvard University’s Center for Transcriptional Consequences of Human Genetic Variation;
  • Johns Hopkins University’s Center for the Epigenetics of Common Human Disease;
  • Stanford University’s Center for the Genomic Basis of Vertebrate Diversity;
  • Arizona State University’s Microscale Life Sciences Center;
  • Medical College of Wisconsin, Milwaukee’s Center of Excellence in Genomics Science;
  • The University of North Carolina at Chapel Hill‘s CISGen center;
  • The Broad Institute’s Center for Cell Circuits;
  • Yale University’s Center for the Analysis of Human Genome Using Integrated Technologies; and
  • Dana-Farber Cancer Institute‘s Center for Genomic Analysis of Network Perturbations in Human Disease.

Center for In Toto Genomic Analysis of Vertebrate Development

P50 HG004071
Marianne Bronner-Fraser
California Institute of Technology, Pasadena, Calif.

This Center of Excellence in Genomic Science (CEGS) assembles a multidisciplinary group of investigators to develop innovative technologies with the goal of imaging and mutating every developmentally important vertebrate gene. Novel “in toto imaging” tools make it possible to use a systems-based approach for analysis of gene function in developing vertebrate embryos in real time and space. These tools can digitize in vivo data in a systematic, high-throughput, and quantitative fashion. Combining in toto imaging with novel gene traps permits a means to rapidly screen for developmentally relevant expression patterns, followed by the ability to immediately mutagenize genes of interest. Initially, key technologies will be developed and tested in the zebrafish embryo due to its transparency and the ability to obtain rapid feedback. Once validated, these techniques will be applied to an amniote, the avian embryo, due to several advantages including accessibility and similarity to human embryogenesis. Finally, to monitor alterations in gene expression in normal and mutant embryos, we will develop new techniques for in situ hybridization that permit simultaneous analysis of multiple marker genes in a sensitive and potentially quantitative manner. Our goal is to combine real time analysis of gene expression on a genome-wide scale coupled with the ability to mutate genes of interest and examine global alterations in gene expression as a result of gene loss. Much of the value will come from the development of new and broadly applicable technologies. In contrast to a typical technology development grant, however, there will be experimental fruit emerging from at least two vertebrate systems (zebrafish and avian). The following aims will be pursued: Specific Aim 1: Real-time “in toto” image analysis of reporter gene expression; Specific Aim 2: Comprehensive spatiotemporal analysis of gene function of the developing vertebrate embryo using the FlipTrap approach for gene trapping; Specific Aim 3: Design of quantitative, multiplexed ‘hybridization chain reaction’ (HCR) amplifiers for in vivo imaging with active background suppression; Specific Aim 4: Data analysis and integration of data sets to produce a “digital” fish and a “digital” bird. The technologies and the resulting atlases will be made broadly available via electronic publication.

Causal Transcriptional Consequences of Human Genetic Variation

P50 HG005550
George M. Church
Harvard University, Cambridge, Mass.

The Center for Transcriptional Consequences of Human Genetic Variation (CTCHGV) will develop innovative and powerful genetic engineering methods and use them to identify genetic variations that causally control gene transcription levels. Genome Wide Association Studies (GWAS) find many variations associated with disease and other phenotypes, but the variations that may actually cause these conditions are hard to identify because nearby variations in the same haplotype blocks consistently co-occur with them in human populations, so that specifically causative ones cannot be distinguished. About 95% of GWAS variations are not in gene coding regions, and many of these presumably associate with altered gene expression levels. CTCHGV will identify the variations that directly control gene expression by engineering precise combinations of changes to gene regulatory regions that break down the haplotype blocks, allowing each variations’ effect on gene expression to be discerned independently of the others. To perform this analysis, CTCHGV will extract ~100kbps gene regulatory regions from human cell samples, create precise variations in them in E. coli, and re-introduce the altered regions back into human cells, using zinc finger nucleases (ZFNs) to efficiently induce recombination. CTCHGV will target 1000 genes for this analysis (Aim 1), and will use human induced Pluripotent Stem cells (iPS) to study the effects of variations in diverse human cell types (Aim 2). To explore the effects of variations in complex human tissues, CTCHGV will develop methods of measuring gene expression at transcriptome-wide levels in many single cells, including in situ in structured tissues (Aim 3). Finally, CTCHGV will develop novel advanced technologies that integrate DNA sequencing and synthesis to construct thousands of large DNA constructs from oligonucleotides, that enable very precise targeting and highly efficient performance of ZFNs, and that enable cells to be sorted on the basis of morphology as well as fluorescence and labeling (Aim 4). CTCHGV will also develop direct oligo-mediated engineering of human cells, and create “marked allele” iPS that will enable easy ascertainment of complete exon distributions for many pairs of gene alleles in many cell types.

Center for the Epigenetics of Common Human Disease

P50 HG003233
Andrew P. Feinberg
Johns Hopkins University, Baltimore
(co-funded by National Institute of Mental Health)

Epigenetics, the study of non-DNA sequence-related heredity, is at the epicenter of modern medicine because it can help to explain the relationship between an individual’s genetic background, the environment, aging, and disease. The Center for the Epigenetics of Common Human Disease was created in 2004 to begin to develop the interface between epigenetics and epidemiologic-based phenotype studies, recognizing that epigenetics requires new ways of thinking about disease. We created a highly interdisciplinary group of faculty and trainees, including molecular biologists, biostatisticians, epidemiologists, and clinical investigators. We developed novel approaches to genome-wide DNA methylation (DNAm) analysis, allele-specific expression, and new statistical epigenetic tools. Using these tools, we discovered that most variable DNAm is in neither CpG islands nor promoters, but in what we term “CpG island shores,” regions of lower CpG density up to several kb from islands, and we have found altered DNAm in these regions in cancer, depression and autism. In the renewal period, we will develop the novel field of epigenetic epidemiology, the relationship between epigenetic variation, genetic variation, environment and phenotype. We will continue to pioneer genome-wide epigenetic technology that is cost effective for large scale analysis of population-based samples, applying our knowledge from the current period to second-generation sequencing for epigenetic measurement, including DNAm and allele-specific methylation. We will continue to pioneer new statistical approaches for quantitative and binary DNAm assessment in populations, including an Epigenetic Barcode. We will develop Foundational Epigenetic Epidemiology, examining: time-dependence, heritability and environmental relationship of epigenetic marks; heritability in MZ and DZ twins; and develop an epigenetic transmission disequilibrium test. We will then pioneer Etiologic Epigenetic Epidemiology, by integrating novel genome-wide methylation scans (GWMs) with existing Genome-Wide Association Study (GWAS) and epidemiologic phenotype data, a design we term Genome-Wide Integrated Susceptibility (GWIS), focusing on bipolar disorder, aging, and autism as paradigms for epigenetic studies of family-based samples, longitudinal analyses, and parent-of-origin effects, respectively. This work will be critical to realizing the full value of previous genetic and phenotypic studies, by developing and applying molecular and statistical tools necessary to integrate DNA sequence with epigenetic and environmental causes of disease.

Genomic Basis of Vertebrate Diversity

P50 HG002568
David M. Kingsley
Stanford University, Stanford, Calif.

The long-term goal of this project is to understand the genomic mechanisms that generate phenotypic diversity in vertebrates. Rapid progress in genomics has provided nearly complete sequences for several organisms. Comparative analysis suggests many fundamental pathways and gene networks are conserved between organisms. And yet, the morphology, physiology, and behavior of different species are obviously and profoundly different. What are the mechanisms that generate these key differences? Are unique traits controlled by few or many genetic changes? What kinds of changes? Are there particular genes and mechanisms that are used repeatedly when organisms adapt to new environments? Can better understanding of these mechanisms help explain dramatic differences in disease susceptibility that also exist between groups? The Stanford CEGS will use an innovative combination of approaches in fish, mice, and humans to identify the molecular basis of major phenotypic change in natural populations of vertebrates. Specific aims include: 1) cross stickleback fish and develop a genome wide map of the chromosomes, genes, and mutations that control a broad range of new morphological, physiological, and behavioral traits in natural environments; 2) test which population genetic measures provide the most reliable “signatures of selection” surrounding genes that are known to have served as the basis of parallel adaptive change in many different natural populations around the world; 3) assemble the stickleback proto Y chromosome and test whether either sex or autosomal rearrangements play an important role in generating phenotypic diversity, or are enriched in genomic regions that control phenotypic change; 4) test whether particular genes and mechanisms are used repeatedly to control phenotypic change in many different vertebrates. Preliminary data suggests that mechanisms identified as the basis of adaptive change in natural fish populations may be broadly predictive of adaptive mechanisms across a surprisingly large range of animals, including humans. Genetic regions hypothesized to be under selection in humans will be compared to genetic regions under selection in fish. Regions predicted to play an important role in natural human variation and disease susceptibility will be modeled in mice, generating new model systems for confirming functional variants predicted from human population genetics and comparative genomics.

Microscale Life Sciences Center

P50 HG002360
Deirdre R. Meldrum
Arizona State University, Tempe

Increasingly, it is becoming apparent that understanding, predicting, and diagnosing disease states is confounded by the inherent heterogeneity of in situ cell populations. This variation in cell fate can be dramatic, for instance, one cell living while an adjacent cell dies. Thus, in order to understand fundamental pathways involved in disease states, it is necessary to link preexisting cell state to cell fate in the disease process at the individual cell level.

The Microscale Life Sciences Center (MLSC) at the University of Washington is focused on solving this problem, by developing cutting-edge microscale technology for high throughput genomic-level and multi-parameter single-cell analysis, and applying that technology to fundamental problems of biology and health. Our vision is to address pathways to disease states directly at the individual cell level, at increasing levels of complexity that progressively move to an in vivo understanding of disease. We propose to apply MLSC technological innovations to questions that focus on the balance between cell proliferation and cell death. The top three killers in the United States, cancer, heart disease and stroke, all involve an imbalance in this cellular decision-making process. Because of intrinsic cellular heterogeneity in the live/die decision, this fundamental cellular biology problem is an example of one for which analysis of individual cells is essential for developing the link between genomics, cell function, and disease. The specific systems to be studied are proinflammatory cell death (pyroptosis) in a mouse macrophage model, and neoplastic progression in the Barrett’s Esophagus (BE) precancerous model. In each case, diagnostic signatures for specific cell states will be determined by measuring both physiological (cell cycle, ploidy, respiration rate, membrane potential) and genomic (gene expression profiles by single-cell proteomics, qRT-PCR and transcriptomics; LOH by LATE-PCR) parameters. These will then be correlated with cell fate via the same sets of measurements after a challenge is administered, for instance, a cell death stimulus for pyroptosis or a predisposing risk factor challenge (acid reflux) for BE. Ultimately, time series will be taken to map out the pathways that underlie the live/die decision.

Finally, this information will be used as a platform to define cell-cell interactions at the single-cell level, to move information on disease pathways towards greater in vivo relevance. New technology will be developed and integrated into the existing MLSC Living Cell Analysis cassette system to support these ambitious biological goals including 1) automated systems for cell placement, off-chip device interconnects, and high throughput data analysis with user friendly interfaces; 2) new optical and electronic sensors based on a new detection platform, new dyes and nanowires; and 3) new micromodules for single-cell qRT-PCR, LATE-PCR for LOH including single-cell pyrosequencing, on-chip single-cell proteomics, and single-cell transcriptomics using barcoded nanobeads.

Wisconsin Center of Excellence in Genomics Science

P50 HG004952
Michael Olivier
Medical College of Wisconsin, Milwaukee

The successful completion of the human genome and model organism sequences has ushered in a new era in biological research, with attention now focused on understanding the way in which genome sequence information is expressed and controlled. The focus of this proposed Wisconsin Center of Excellence in Genomics Science is to facilitate understanding of the complex and integrated regulatory mechanisms affecting gene transcription by developing novel technology for the comprehensive characterization and quantitative analysis of proteins interacting with DNA. This new technology will help provide for a genome-wide functional interpretation of the underlying mechanisms by which gene transcriptional regulation is altered during biological processes, development, disease, and in response to physiological, pharmacological, or environmental stressors. The development of chromatin immunoprecipitation approaches has allowed identification of the specific DNA sequences bound by proteins of interest. We propose to reverse this strategy and develop an entirely novel technology that will use oligonucleotide capture to pull down DNA sequences of interest, and mass spectrometry to identify and characterize the proteins and protein complexes bound and associated with particular DNA regions. This new approach will create an invaluable tool for deciphering the critical control processes regulating an essential biological function. The proposed interdisciplinary and multi-institutional Center of Excellence in Genomics Science combines specific expertise at the Medical College of Wisconsin, the University of Wisconsin Madison, and Marquette University. Technological developments in four specific areas will be pursued to develop this new approach: (1) cross-linking of proteins to DNA and fragmentation of chromatin; (2) capture of the protein-DNA complexes in a DNA sequence-specific manner; (3) mass spectrometry analysis to identify and quantify bound proteins; and (4) informatics to develop tools enabling the global analysis of the relationship between changes in protein-DNA interactions and gene expression. The Center will use carefully selected biological systems to develop and test the technology in an integrated genome-wide analysis platform that includes efficient data management and analysis tools. As part of the Center mission, we will combine our technology development efforts with an interdisciplinary training program for students and fellows designed to train qualified scientists experienced in cutting-edge genomics technology. Data, technology, and software will be widely disseminated by multiple mechanisms including licensing and commercialization activities.

CISGen

P50 MH090338
Fernando Pardo-Manuel de Villena
University of North Carolina, Chapel Hill

p>In this application, we propose a highly ambitious yet realistically attainable goal: to align existing expertise at UNC-Chapel Hill into a CEGS called CISGen. The overarching purpose of CISGen is to develop as a resource and to exploit the utility of the murine Collaborative Cross (CC) mouse model of the heterogeneous human population to delineate genetic and environmental determinants of complex phenotypes drawn from psychiatry, which are among the most intractable set of problems in all of biomedicine. Psychiatric disorders present a paradox – the associated morbidity, mortality, and costs are enormous and yet, despite over a century of scientific study, there are few hard facts about the etiology of the core diseases. Although our GWAS meta- analyses are in progress, early results suggest that strong and replicable findings may be elusive. Therefore, our proposal provides a complementary approach to the study of fundamental psychiatric phenotypes.

We propose a particularly challenging definition of success – we will identify high probability etiological models (which can be realistically complex) and then prove the predictive capacity of these models by generating novel strains of mice predicted to be at very high risk for the phenotype. Once validated, these high confidence models can then be tested in subsequent human studies – we do not propose human extension studies in CISGen but this is achievable for the investigators and their colleagues. Data collected in CISGen would be a valuable resource to the wider scientific community and could be applied to a large set of biological problems and these data can rapidly add to the knowledge base for any new genomewide association study (GWAS) finding. Delivery of sophisticated and user-friendly databases are a key component of CISGen.

Accomplishing this overarching goal requires an exceptional diversity of scientific expertise – psychiatry, human genetics, mouse behavior, mouse genetics, statistical genetics, computational biology, and systems biology. Experts in these disciplines are deeply involved in CISGen and are committed to the projects described herein. Successful integration of these diverse fields is non-trivial; however, all scientists on this application have had extensive interactions over the past five years, already know how to work together, and have a working knowledge of their colleagues’ expertise. UNC-Chapel Hill has an intense commitment to inter- disciplinary genomics research and provides a fertile backdrop for 21st century projects like CISGen.

Center for Cell Circuits

P50 HG006193
Aviv Regev
The Broad Institute, Inc., Cambridge, Mass.

Systematic reconstruction of genetic and molecular circuits in mammalian cells remains a significant, largescale and unsolved challenge in genomics. The urgency to address it is underscored by the sizeable number of GWAS-derived disease genes whose functions remain largely obscure, limiting our progress towards biological understanding and therapeutic intervention. Recent advances in probing and manipulating cellular circuits on a genomic scale open the way for the development of a systematic method for circuit reconstruction. Here, we propose a Center for Cell Circuits to develop the reagents, technologies, algorithms, protocols and strategies needed to reconstruct molecular circuits. Our preliminary studies chart an initial path towards a universal strategy, which we will fully implement by developing a broad and integrated experimental and computational toolkit. We will develop methods for comprehensive profiling, genetic perturbations and mesoscale monitoring of diverse circuit layers (Aim 1). In parallel, we will develop a computational framework to analyze profiles, derive provisional models, use them to determine targets for perturbation and monitoring, and evaluate, refine and validate circuits based on those experiments (Aim 2). We will develop, test and refine this strategy in the context of two distinct and complementary mammalian circuits. First, we will produce an integrated, multi-layer circuit of the transcriptional response to pathogens in dendritic cells (Aim 3) as an example of an acute environmental response. Second, we will reconstruct the circuit of chromatin factors and non-coding RNAs that control chromatin organization and gene expression in mouse embryonic stem cells (Aim 4) as an example of the circuitry underlying stable cell states. These detailed datasets and models will reveal general principles of circuit organization, provide a resource for scientists in these two important fields, and allow computational biologists to test and develop algorithms. We will broadly disseminate our tools and methods to the community, enabling researchers to dissect any cell circuit of interest at unprecedented detail. Our work will open the way for reconstructing cellular circuits in human disease and individuals, to improve the accuracy of both diagnosis and treatment.

Analysis of Human Genome Using Integrated Technologies

P50 HG002357
Michael P. Snyder
Yale University, New Haven, Conn.

We propose to establish a center to build genomic DNA arrays and develop novel technologies that will use these arrays for the large-scale functional analysis of the human genome. 0.3-1.4 kb fragments of nonrepetitive DNA from each of chromosomes 22, 21, 20, 19,7, 17, and perhaps the X chromosome will be prepared by PCR and attached to microscope slides. The arrays will be used to develop technologies for the large-scale mapping of 1) Transcribed sequences. 2) Binding sites of chromosomal proteins. 3) Origins of replication. 4) Genetic mutation and variation. A web-accessible database will be constructed to house the information generated in this study; data from other studies will also be integrated into the database. The arrays and technologies will be made available throughout both the Yale University and the larger scientific community. They will be integrated into our training programs for postdoctoral fellows, graduate students and undergraduates at Yale. We expect these procedures to be applicable to the analysis of the entire human genome and the genomes of many other organisms.

Genomic Analysis of the Genotype-Phenotype Map

P50 HG002790
Simon Tavaré
University of Southern California, Los Angeles

Our Center, which started in 2003, focused on implications of haplotype structure in the human genome. Since that time, there have been extraordinary advances in genomics: Genome-wide association studies using single nucleotide polymorphisms and copy number variants are now commonplace, and we are rapidly moving towards whole-genome sequence data for large samples of individuals. Our Center has undergone similar dramatic changes. While the underlying theme remains the same — making sense of genetic variation — our focus is now explicitly on how we can use the heterogeneous data produced by modern genomics technologies to achieve such an understanding. The overall goal of our proposal is to develop an intellectual framework, together with computational and statistical analysis tools, for illuminating the path from genotype to phenotype, and for predicting the latter from the former. We will address three broad questions related to this problem: 1) How do we infer mechanisms by which genetic variation leads to changes in phenotype? 2) How do we improve the design, understanding and interpretation of association studies by exploiting prior information? 3) How do we identify general principles about the genotype-phenotype map? We will approach these questions through a series of interrelated projects that combine computational and experimental methods, explored in Arabidopsis, Drosophila and human, and involve a wide range of researchers including molecular biologists, population geneticists, genetic epidemiologists, statisticians, computer scientists, and mathematicians.

Genomic Analysis of Network Perturbations in Human Disease

P50 HG004233
Marc Vidal
Dana-Farber Cancer Institute, Boston

Genetic differences between individuals can greatly influence their susceptibility to disease. The information originating from the Human Genome Project (HGP), including the genome sequence and its annotation, together with projects such as the HapMap and the Human Cancer Genome Project (HCGP) have greatly accelerated our ability to find genetic variants and associate genes with a wide range of human diseases. Despite these advances, linking individual genes and their variations to disease remains a daunting challenge. Even where a causal variant has been identified, the biological insight that must precede a strategy for therapeutic intervention has generally been slow in coming. The primary reason for this is that the phenotypic effects of functional sequence variants are mediated by a dynamic network of gene products and metabolites, which exhibit emergent properties that cannot be understood one gene at a time. Our central hypothesis is that both human genetic variations and pathogens such as viruses influence local and global properties of networks to induce “disease states.” Therefore, we propose a general approach to understanding cellular networks based on environmental and genetic perturbations of network structure and readout of the effects using interactome mapping, proteomic analysis, and transcriptional profiling. We have chosen a defined model system with a variety of disease outcomes: viral infection. We will explore the concept that one must understand changes in complex cellular networks to fully understand the link between genotype, environment, and phenotype. We will integrate observations from network-level perturbations caused by particular viruses together with genome-wide human variation datasets for related human diseases with the goal of developing general principles for data integration and network prediction, instantiation of these in open-source software tools, and development of testable hypotheses that can be used to assess the value of our methods. Our plans to achieve these goals are summarized in the following specific aims: 1. Profile all viral-host protein-protein interactions for a group of viruses with related biological properties. 2. Profile the perturbations that viral proteins induce on the transcriptome of their host cells. 3. Combine the resulting interaction and perturbation data to derive cellular network-based models. 4. Use the developed models to interpret genome-wide genetic variations observed in human disease, 5. Integrate the bioinformatics resources developed by the various CCSG members within a Bioinformatics Core for data management and dissemination. 6. Building on existing education and outreach programs, we plan to develop a genomic and network centered educational program, with particular emphasis on providing access for underrepresented minorities to internships, workshop and scientific meetings.

Paralysis by Sequestration and the Medical Revolution

Dysfunction and the Medical Revolution

http://www.genomeweb.com/blog/dysfunction-and-medical-revolution
April 02, 2013
The federal sequestration is cutting back or halting grants that fund “potentially groundbreaking” personalized medicine research funded by the National Institutes of Health, Institute for Systems Biology President Lee Hood opines. Taking his pen to the pages of The Hill, Hood writes that political three-way fisticuffs between lawmakers in both houses and the White House that led to the sequester — an across-the-board five percent whack to all agency budgets — could imperil advances in personalized medicine research that ISB is pursuing.
Hood praises the promise of what he calls P4 medicine, the convergence of new big data and genomic technologies to develop “medicine that is predictive, personalized, preventive, and participatory.”
The forward march of P4 will bring about a new type of medicine, Hood writes, that will improve care through diagnoses and targeted therapies. It also will save money in the long run because new and better treatments and predictive medicine will “reduce the skyrocketing costs of healthcare” and help create new “wellness sector” markets and companies that don’t yet exist, he says.
“In 1986, the automated DNA sequencer I invented was first brought to market, paving the way for the Human Genome Project completed in 2003. In 2010 alone, human genome sequencing activities generated $67 billion in US economic output and created 310,000 US jobs,” he says.
Hood doesn’t want to see a dysfunctional political culture on Capitol Hill hinder the advance of these technologies, markets, and medical innovations.
“On the 10th anniversary of the completion of the Human Genome Project, we can’t let the ongoing tug-of-war in Congress over spending priorities threaten the revolutionary work that is taking place in medical science,” he writes.

Couldn’t agree more. I was just up on the Hill meeting with Representatives, and they are sadly bogged down in the sequester. Meanwhile, Medicare has suspended reimbursements for molecular diagnostic testing. Congress is missing an entire paradigm change where the art of patient care has led to the rapid emergence of Personalized Medicine. Without appropriate funding, we will not be able to educate patients, clinicians, reimbursement directors, and Congress themselves on the astounding advancements that have been made in personalized medicine. We can perform whole genome sequencing to identify clinically relevant mutations in individual patient’s tumors- morally, this technology could and should be available to all late stage cancer patients immediately. Frustratingly, we lack the political leadership and vision. In an environment where jobs for many experienced, bright scientists are so desperately needed, the failure of governmental leadership has led to the siphoning off of technological development and jobs to other more perceptive countries. This is a mess that can be corrected in no time with appropriate leadership from the three branches that Dr. Hood mentions. Here’s hoping that Dr. Hood’s communication will open some eyes.

Ethical Concerns in Personalized Medicine: BRCA1/2 Testing in Minors and Communication of Breast Cancer Risk

Reporter/Curator: Stephen J. Williams, Ph.D.

ethicspersonalizedmedicine-page1

Dealing with the unexpected: consumer responses to direct-access BRCA mutation testing[1]

Direct-to-consumer (DTC) genetic testing and genetic health information in 2007 with the advent of personalized testing services by companies who offered microarray-based genotyping of single-nucleotide-polymorphisms (SNP) which had strong correlations to disease risk.  Three companies started to offer such services directly to the consumer:

A common test which is offered analyzes the consumers BRCA1/2 mutation status.  Three mutations in the BRCA gene are known to predispose women to hereditary breast and ovarian cancer: BRCA1 185delAG, BRCA1 538insC, and BRCA2 617delT.  These BRCA1 mutation confer a 60% breast cancer risk and a 40% risk of ovarian cancer while the BRCA2 mutation confers a breast cancer risk of 50% and 20% risk of ovarian cancer.

However, the commercial availability of this genetic disease-risk associated testing has led to certain ethical issues concerning communication and responses of risk information by:

  1. Consumers who request BRCA1/2 testing (focus of the Francke article
  2. BRCA1/1 testing and communication of results to minors and relatives (Bradbury: see below)

There has been much opinion, either as commentary in literature, meeting proceedings, or communiques from professional societies warning that this type of “high-impact” genetic information should not be given directly to the consumer as consumers will not fully understand the information presented to them, be unable to make proper risk-based decisions, results could cause panic and inappropriate action such as prophylactic oophorectomy or unwarranted risk-reduction mastectomy, or false reassurance in case of negative result and reduced future cancer screening measures taken by the consumer.  However, there have been few studies to investigate these concerns.

A report by Dr. Uta Francke in the open access journal PeerJ, assesses and quantifies the emotional and behavioral reactions of consumers to their 23andMe Personal Genome Service® report of the three BRCA mutations known to be associated with high risk for breast/ovarian cancer.  One hundred thirty six (136) individuals, who tested positive for BRCA1 and/or BRCA2 mutations as well as 160 users of the service, who tested mutation-free were invited to participate in phone interviews addressing personal and family history of cancer, decision and timing of viewing the BRCA report, recollection of results, emotional responses, perception of personal cancer risk, information sharing, and actions taken.  Thirty two (32) mutation carriers (16 female and 16 male) and 31 non-carriers responded to the phone questionnaire.

Questions were based on the following themes:

  1. When you purchased the 23andME Personal Genome Service® were you aware that it included testing for mutations that predispose to breast and ovarian cancer?
  2. Were you aware that having Ashkenazi Jewish ancestry influences your risk of carrying one of the three mutations?
  3. Have you or a first or second degree relative been diagnosed with breast, ovarian or any other cancer?
  4. What did you learn from your results?
  5. Were you surprised by the result?
  6. How did you feel about this information (extremely, moderately, somewhat upset or extremely relieved)?

Results:  Eleven women and 14 men had received an unexpected result that they are carriers of one of the three mutations however none of them reported extreme anxiety and only four reported moderate anxiety which did not last long.  Participants were at least 8 years of age. Five women and six men described their reaction as neutral.  Most carrier women sought medical advice and four underwent risk-reducing procedures. Some to the male carriers felt burdened to share their test results with their female relatives, which led to additional screenings of relatives.  Almost all of the mutation-positive customers appreciated learning their BRCA mutational status.

Other highlights of the results include:

  • More women got tested if they had a first or second degree relative previously diagnosed with breast/ovarian cancer
  • Ten mutation-positive individuals who were surprised at the test results cited the lack of family history of breast/ovarian cancer as the reason for their surprise.  The rest who were surprised at their positive test results believed that the frequency of these mutations were low in the general population so they shouldn’t have been affected.
  • For the mutation-positive group, none of the 32 reported as being “extremely upset”.
  • Interestingly, on male who learned, for the first time, he was a positive carrier for BRCA mutation, reported feeling “relieved” because his daughter who was also tested by 23andMe had not acquired his mutation.

A brief interview with Dr. Francke follows:

Q:     In your results you had noted that none of the mutation carriers showed extreme anxiety about their reports however there were many of Ashkenazi descent who was well aware of the increased risk to breast cancer.  In another study by Dr. Angela Bradbury, anxieties and communication to their children depended on mutation status and education status.  Do you feel that most women in your study were initially aware they could be in a high risk category for cancer, whether breast, ovarian, or other?

Dr. Francke:   As we show in Table 1, 6 of 16 women and 6 of 16 men who found out that they were BRCA mutation carriers had not been aware that being of Ashkenazi descent confers an increased risk of breast/ovarian cancer.  In Table S1, we show that 6 of these 32 people did not self-identify as Ashkenazi.
Q:     The reporting and communication of test results to offspring and genetic testing of offspring as a result of positive tests has been under much debate.  I had noticed that there was a high proportion of relatives who went for screening after learning of a family members BRCA testing, whether it showed a mutation or not.  Some studies have shown that offspring of carriers may misinterpret genetic testing results and take inappropriate action, such as considering having early testing  before age 25.  It appears some anxiety may be due to misinformation and lack of genetic counseling.  Should these test results be considered in guidelines for oncologist such as NCCN guidelines with respect to informing family members using genetic counselors as an intermediary?

Dr. Francke:    The “high proportion of relatives who went for screening after learning of a family member’s BRCA testing”, were only those related to a BRCA-positive person. Most of the BRCA testing of relatives was done through health care providers at Myriad as these people were eligible for insurance coverage of the test. In our interviews we found no evidence for inappropriate action of carriers or non-carriers. With one exception, we found no evidence for misinterpretation or “anxiety due to lack of genetic counseling”.  In our online reports we recommend genetic counseling for all customers who have questions about their results.

Q:     I was also particularly interested the male carrier felt a heightened burden to tell their offspring.  This has been suggested in other studies.  I would assume the mothers and not the fathers would feet more pressure to tell their children.  Is there a reason for this?
Dr. Francke:     The heightened burden reported by the male carriers was mostly about the realization of the risk for their daughters, not so much about to telling their offspring.  Female carriers were primarily concerned about their own health risk and management, and decision-making about preventive measures – therefore, the risk for offspring appeared to be of secondary concern for them.

However, the availability of this type of predictive genetic testing for hereditary cancer has raised some ethical issues regarding the communication of risk and genetic results to family members and especially offspring, specifically whether informing minors would incur unnecessary testing, anxiety among minors of parents who tested positive for genetic risk-factors, or even premature risk-reduction surgeries or medical interventions.

The aforementioned ethical issues concerning communicating results of BRCA mutational testing to offspring was addressed by two large studies conducted by Dr. Angela Bradbury M.D. and colleagues at Fox Chase Cancer Center Family Risk Assessment Program (now she is at University of Pennsylvania) and University of Chicago Cancer Risk Clinic.  These studies evaluated the parental opinions regarding BRCA1/2 testing of minors, and how parents communicate BRCA1/2 genetic testing with their children.

In the JCO article (Parent Opinions Regarding the Genetic Testing of Minors for BRCA1/2)[2], Bradbury and colleagues used semistructured interviews (yes/no questions and open-ended questions) of 246 parents at Fox Chase and University of Chicago, who underwent BRCA1/2 whether they supported testing of minors in general and testing of their own offspring.  Parents were asked, “If you were deciding, do you think children under 18 years old should be given the opportunity to be tested” and followed by the open-ended question: “Why do (don’t) you support the genetic testing of minors for BRCA1/2?”.

Results:  In response to the first question (Would you support testing in minors) 37% of parents supported testing of minors in the general population.  The follow-up open-ended question revealed that 4% support testing minors in some or all circumstances.  This decision was independent of parent sex or race.  44% of parents would test their own offspring.  Parents who opposed testing in minors thought testing would cause fear and anxiety for their children but those who supported unconditional testing (regardless of whether they were positive for the BRCA mutation or not) mentioned that the medical information would foster better health behaviors in their offspring.  21% of parents who opposed testing minors, in general, actually supported testing of their own children.  Interestingly parents who tested positive for the BRCA1 overwhelmingly (64%) opposed testing of minors, in general.  In addition, statistical analysis of the open-ended questions revealed that parents who did not have a college degree, had a negative test result, and were non white favored testing of their own children.  The authors had suggested larger studies before any guidelines were given as to whether testing in minors of BRCA mutation carriers should be standard.

In a recent publication by Dr. Bradbury and colleagues (Knowledge and perceptions of familial and genetic risks for breast cancer risk in adolescent girls)[3],  studied how adolescent girls understood and responded to breast cancer risk by interviewing 11-19 year-old girls at high-risk and population-risk for breast cancer. Although most girls said they were aware of increased risk because either a family member had or was predisposed to breast cancer (66 %) only 17 % of girls were aware of BRCA1/2 genes. Mother was the most frequently reported source of information for breast cancer among both high-risk (97 %) and population-risk (89 %) girls.  The study also showed that most girls who believe they are at high-risk could alter their lifestyles or change dietary habits to lower their risk.

In an adjacent study in the journal Cancer[4], Bradbury and colleagues at Fox Chase Cancer Center had gauged the frequency with which parents had told their children of their BRCA1/2 teat results and how their children felt about the results.

When parents disclose BRCA1/2 test results: Their communication and perceptions of offspring response[4]

Semi-structured interviews were conducted with parents who had BRCA1/2 testing and at least 1 child <25 YO.  A total of 253 parents completed interviews (61% response rate), reporting on 505 offspring. Twenty-nine percent of parents were BRCA1/2 mutation carriers. Three hundred thirty-four (66%) offspring learned of their parent’s test result. Older offspring age (P ≤ .01), offspring gender (female, P = .05), parents’ negative test result (P = .03), and parents’ education (high school only, P = .02) were associated with communication to offspring. The most frequently reported initial offspring responses were neutral (41%) or relief (28%). Thirteen percent of offspring were reported to experience concern or distress (11%) in response to parental communication of their test results. Distress was more frequently perceived among offspring learning of their parent’s BRCA1/2 positive or variant of uncertain significance result.

CONCLUSIONS:

Many parents communicate their BRCA1/2 test results to young offspring. Parents’ perceptions of offspring responses appear to vary by offspring age and parent test result. A better understanding of how young offspring respond to information about hereditary risk for adult cancer could provide opportunities to optimize adaptive psychosocial responses to risk information and performance of health behaviors, in adolescence and throughout an at-risk life span.

Below is an excellent article by Steven Reinberg from HealthDay interviewing Dr. Angela Bradbury concerning their JCO study: (reported for ABC News at http://abcnews.go.com/Health/Healthday/story?id=4508346&page=1#.UVNJUVef2RM)

Many Parents Share Genetic Test Findings With Kids

By Steven Reinberg
HealthDay Reporter

Mar. 23

FRIDAY, Aug. 17 (HealthDay News) — As genetic testing for diseases becomes more commonplace, the impact of those findings on family members may be underestimated, researchers say.

For instance, some women who discover they have the BRCA gene mutation, which puts them at higher risk for breast cancer, choose to tell their children about it before the children are old enough to understand the significance or deal with it, a new study found.

“Parents with the BRCA mutation are discussing their genetic test results with their offspring often many years before the offspring would need to do anything,” said study author Dr. Angela Bradbury, director of the Fox Chase Cancer Center’s Family Risk Assessment Program, in Philadelphia.

According to Bradbury, more than half of parents she surveyed told their children about genetic test results. Some parents reported that their children didn’t seem to understand the significance of the information, and some had initial negative reactions to the news.

“A lot of genetic information is being shared within families and there hasn’t been a lot of guidance from health-care professionals,” Bradbury said. “While this genetic risk may be shared accurately, there is risk of inaccurate sharing.”

In the study, Bradbury’s team interviewed 42 women who had the BRCA mutation. The researchers found that 55 percent of parents discussed the finding and the risk of breast cancer with at least one of their children who was under 25.

Also, most of the women didn’t avail themselves of the services of a doctor or genetic counselor in helping to tell their children, Bradbury’s group found.

Bradbury is concerned that sharing genetic information with young children can create anxiety. “The children could be overly concerned about their own risk at a time when there is nothing that they need to do,” she said.

But, she added, “it may be possible that sharing may be good for children in adapting to this information.”

The findings are published in the Aug. 20 issue of the Journal of Clinical Oncology.

The lack of definitive data on when — or if — to discuss genetic test results with children is a real problem, Bradbury said.

“As we move genetic testing forward for cancer or other illnesses, we have to consider the context of the whole family and focus our counseling to the whole family, and not just the person who comes in for testing,” Bradbury said. “We should learn more about how and when we should talk to children about this, so that we can promote healthy behaviors without causing too much anxiety for the offspring.”

Barbara Brenner, executive director of Breast Cancer Action, agreed that the psychological component of genetic testing needs more attention.

“This is the tip of a very scary iceberg,” Brenner said. “We don’t know the psychological consequences [of BRCA testing], not only to the person who has the test, but to her family members.”

Brenner thinks guidelines to help parents deal with this information are needed. So is help from doctors and genetic counselors in counseling family members, especially children, she added.

Personalized Medicine: Clinical Aspiration of Microarrays

Reporter, Writer: Stephen J. Williams, Ph.D.

 In this month’s Science, Mike May (at http://www.sciencemag.org/site/products/lst_20130215.xhtml) describes some of the challenges and successes in introducing microarray analysis to the clinical setting.  Traditionally used for investigational research, microarray is now being developed, customized and used for biomarker analysis, prognostic and predictive value, in a disease-specific manner.

Challenges in data interpretation

      In an interview with Seth Crosby, director of the Genome Technology Access Center at Washington University School of Medicine in St. Louis, “the biggest challenge” in moving microarray to the clinical setting is data interpretation.  The current technology makes it possible to evaluate expression of thousands of genes from a patient’s sample however as Crosby describes is assigning clinical relevance to the data.  For example Crosby explains that Washington University had validated a panel of 45 oncology genes by next generation sequencing and are using these genes to develop diagnostic tests to screen patient tumors for the purpose of determining a personalized therapeutic strategy. Seth Crosby noted it took “hundreds of Ph.D. and M.D. hours” to sift through the hundreds of papers to determine which genes were relevant to a specific cancer type. However, he notes, that once we better understand which changes in the patient’s genome are related to a specific disease we will be able to narrow down the list and be able to produce both economical and more disease-relevant microarrays.

Is this aberration pathogenic or not?

     Microarrays are becoming an invaluable tool in cytogenetics, as eluded by Andy Last, executive vice president of the genetic analysis business unit at Affymetrix.  Certain diseases like Down syndrome have well characterized chromosomal alterations like additions or deletions of parts or entire chromosomes.  According to Affymetrix, the most common use of microarrays is for determining copy number variation.  However according to James Clough, vice president of clinical and genomic services at Oxford Gene Technology, given the hundreds of syndromes associated with chromosomal rearrangements, the challenge will be to determine if a small chromosomal aberration has pathologic significance, given that microarray affords much higher diagnostic yield and speed of analysis than traditional microscopic techniques.  To address this challenge, Oxford Gene Technologies, PerkinElmer, Affymetrix, and Agilent all have custom designed microarrays to evaluate disease specific copy number and SNP (single nucleotide polymorphism) microarrays.  For example PerkinElmer designed OncoChip™ to evaluate copy number variation in more than 1.800 cancer genes.  Agilent makes microarrays that evaluates both copy number variation such as its CGH (comparative genomic hybridization) plus SNP microarrays.  Patricia Barco, product manager for cytogenetics at Agilent, notes these arrays can be used in prenatal and postnatal research and cancer, and “can be customized from more than 28 million probes in our library”.

Custom Tools and Software to Handle the Onslaught of Big Data

     There is a need for FDA approved diagnostic tools based on microarrays. Pathwork Diagnostic’s has one such tool (the Pathwork Tissue of Origin test), which uses 2,000 transcript markers and a proprietary computational algorithm to determine from expression analysis, the tissue of origin of a patient’s tumor.  Pathwork also provides a fast, custom turn-around analytical service for pathologists who encounter difficult to interpret samples.  Illumina provides the Infinium HumanCore BeadChip family of microarrays, which can determine genetic variations for purposes of biological tissue banking.  This system uses a set of over 300,000 SNP probes plus 240,000 exome-based markers.

     Tools have also been developed to validate microarray results.  A common validation strategy is the use of quantitative real-time PCR to verify the expression changes seen on the microarray.  Life Technologies developed the TaqMan OpenArray Real Time PCR plates, which have 3,072 wells and can be custom-formatted using their library of eight million validated TaqMan assays.

Making Sense of the Big Data: Bridging the Knowledge Gap using Bioinformatics

          The use of microarray has spurned industries devoted to developing the bioinformatics software to analyze the massive amounts of data and provide clinical significance.  For example companies such as Expression Analysis use their bioinformatics software to provide pathway analysis for microarray data in order to translate the data into the biology.  Using such strategies can also validate the design of microarrays for various diseases.

Foundation Medicine, Inc., a molecular information company, provides cancer genomics test solutions. It offers FoundationOne, an informative genomic profile to identify a patient’s individual molecular alterations and match them with relevant targeted therapies and clinical trials. The company’s product enables physicians to recommend treatment options for patients based on the molecular subtype of their cancer.

The Canadian Bioinformatics Workshops series recently offered a course on using bioinformatic approaches to analyze clinical data generated from microarray approaches (http://bioinformatics.ca/workshops/2012/bioinformatics-cancer-genomics-bicg).   The course objectives are described below:

Course Objectives

Cancer research has rapidly embraced high throughput technologies into its research, using various microarray, tissue array, and next generation sequencing platforms. The result has been a rapid increase in cancer data output and data types. Now more than ever, having the bioinformatic skills and knowledge of available bioinformatic resources specific to cancer is critical. The CBW will host a 5-day workshop covering the key bioinformatics concepts and tools required to analyze cancer genomic data sets. Participants will gain experience in genomic data visualization tools which will be applied throughout the development of the skills required to analyze cancer -omic data for gene expression, genome rearrangement, somatic mutations and copy number variation. The workshop will conclude with analyzing and conducting pathway analysis on the resultant cancer gene list and integration of clinical data.

Successful Examples of Clinical Ventures Integrating Bioinformatics in Cancer Treatment Decision –Making

  • Body

The ONCO-i2b2 project, supported by the University of Pavia and the Fondazione Salvatore Maugeri (FSM), aims at supporting translational research in oncology and exploits the software solutions implemented by the Informatics for Integrating Biology and the Bedside (i2b2) research centre, an initiative funded by the NIH Roadmap National Centres for Biomedical Computing. The ONCO-i2b2 software is designed to integrate the i2b2 infrastructure with the FSM hospital information system and the Bruno Boerci Biobank, in order to provide well-characterized cancer specimens along with an accurate patients clinical data-base. The i2b2 infrastructure provides a web-based access to all the electronic medical records of cancer patients, and allow researchers analyzing the vast amount of biological and clinical information, relying on a user-friendly interface. Data coming from multiple sources are integrated and jointly queried.

In 2011 at AIOM Meeting we reported the preliminary experience of the ONCO-i2b2 project, now we’re able to present the up and running platform and the extended data set. Currently, more than 4400 specimens are stored and more than 600 of breast cancer patients give the consent for the use of specimens in the context of clinical research, in addition, more than 5000 histological reports are stored in order to integrate clinical data.

Within the ONCO-i2b2 project is possible to query and merge data regarding:

• Anonymous patient personal data;

• Diagnosis and therapy ICD9-CM subset from the hospital information system;

• Histological data (tumour SNOMED and TNM codes) and receptor profile testing (Her2, Ki67) from anatomic pathology database;

• Specimen molecular characteristics (DNA, RNA, blood, plasma and cancer tissues) from the Bruno Boerci Biobank management system.

The research infrastructure will be completed by the development of new set of components designed to enhance the ability of an i2b2 hive to utilize data generated by NGS technology, providing a mechanism to apply custom genomic annotations. The translational tool created at FSM is a concrete example regarding how the integration of different information from heterogeneous sources could bring scientific research closer to understand the nature of disease itself and to create novel diagnostics through handy interfaces.

Cancer Bioinformatics Program Overview

Over the past five years, NCI’s Center for Biomedical Informatics and Information Technology (CBIIT) has led the effort to develop and deploy the cancer Biomedical Informatics Grid® (caBIG) in partnership with the broader cancer community.  The caBIG network is designed to enable the integration and exchange of data among researchers in the laboratory and the clinic, simplify collaboration, and realize the potential of information-based (personalized) medicine in improving patient outcomes. caBIG has connected major components of the cancer community, including NCI-designated Cancer Centers, participating institutions of the NCI Community Cancer Centers Program (NCCCP), and numerous large-scale scientific endeavors, as well as basic, translational, and clinical researchers at public and private institutions across the United States and around the world.  Beyond cancer research, caBIG capabilities—infrastructure, standards, and tools—provide a prototype for linking other disease communities and catalyzing a new 21st-century biomedical ecosystem that unifies research and care. ARRA funding will allow NCI to accelerate the ongoing development of the Cancer Knowledge Cloud and Oncology Electronic Health Records (EHRs) initiatives, thereby providing for continued job creation in the areas of biomedical informatics development and application as well as healthcare delivery.

The caBIG Cancer Knowledge Cloud: Extending the Research Infrastructure

The Cancer Knowledge Cloud is a virtual biomedical capability that utilizes caBIG tools, infrastructure, and security frameworks to integrate distributed individual and organizational data, software applications, and computational capacity throughout the broad cancer research and treatment community. The Cancer Knowledge Cloud connects, integrates, and facilitates sharing of the diverse primary data generated through basic and clinical research and care delivery to enable personalized medicine. The cloud includes information generated through large-scale research projects such as The Cancer Genome Atlas (TCGA), the cancer Human Biobank (caHUB) tissue acquisition network, the NCI Functional Biology Consortium, the NCI Patient Characterization Center, and the NCI Preclinical Development Pipeline, academic and industry counterparts to these projects, and clinical observations (from entities such as the NCCCP) captured in oncology-extended Electronic Health Records.  Through the use of the caBIG Data Sharing and Security Framework, the Cloud will support appropriate sharing of information, supporting in silico hypothesis generation and testing, and enabling a learning healthcare system.

A caBIG-Based Rapid-Learning Healthcare System: Incorporating Oncology-Extended Electronic Healthcare Records (EHRs)

The 21st-century Cancer Knowledge Cloud will connect individuals, organizations, institutions, and their associated information within an information technology-enabled cycle of discovery, development, and clinical care—the paradigm of a rapid-learning healthcare system. This will transform these disconnected sectors into a system that is personalized, preventive, pre-emptive, and patient-participatory.  To be realized, this model requires the adoption of standards-based EHRs. Presently, however, no certified oncology-based EHR exists, and fewer than 3 percent of oncologists with outpatient-based practices utilize EHRs. caBIG has recently established a collaboration with the American Society of Clinical Oncology (ASCO) to develop an oncology-specific EHR (caEHR) specification based on open standards already in use in the oncology community that will utilize caBIG standards for interoperability. NCI will implement an open-source version of this specification to validate the specification and to provide a free alternative to sites that choose not to purchase a commercial system. The launch customer for the caEHR will be NCCCP participating sites. NCI will work with appropriate entities to provide a mechanism for certifying that caEHR implementations are consistent with the NCI/ASCO specification.

Why we focus on Cancer Bioinformatics

Bioinformatics is a new interdisciplinary area involving biological, statistical and computational sciences. Bioinformatics will enable cancer researchers not only to manage, analyze, mine and understand the currently accumulated, valuable, high-throughput data, but also to integrate these in their current research programs. The need for bioinformatics will become ever more important as new technologies increase the already exponential rate at which cancer data are generated.

What we do

  • We work alongside clinical and basic scientists to support the cancer projects within BCI.  This is an ideal partnership between scientific experts, who know the research questions that will be relevant from a cancer biologist or clinician’s perspective, and bioinformatics experts, who know how to develop the proposed methods to provide answers.
  • We also conduct independent bioinformatics research, focusing on the development of computational and integrative methods, algorithms, databases and tools to tackle the analysis of the high volumes of cancer data.
  • We also are actively involved in the development of bioinformatics educational courses at BCI. Our courses offer a unique opportunity for biologists to gain a basic understanding in the use of bioinformatics methods to access and harness large complicated high-throughput data and uncover meaningful information that could be used to understand molecular mechanisms and develop novel targeted therapeutics/diagnostic tools.

Developing Criteria for Genomic Profiling in Lung Cancer:

A Report from U.S. Cancer Centers

In a report by Pao et. al., a group of clinicians organized a meeting to standardize some protocols for the integration of microarray and genomic data from lung cancer patients into the clinical setting.[1]  There has been ample evidence that adenocarcinomas could be classified into “clinically relevant molecular subsets” based on distinct genomic changes.  For example EGFR (epidermal growth factor receptor) exon 19 deletions and exon 21 point mutations predict sensitivity to tyrosine kinase inhibitors (TKIs) like gefitinib, whereas exon 20 insertions predict primary resistance[2].

However, as the authors note, “mutational profiling has not been widely accepted or adopted into practice in thoracic oncology”.  

     Therefore, a multi-institutional workshop was held in 2009 among participants from Massachusetts General Hospital (MGH) Cancer Center, Memorial Sloan-Kettering Cancer Center (MSKCC), the Dana-Farber/Bingham & Women’s Cancer Center (DF/BWCC), the M.D. Anderson Cancer Center (VICC), and the Vanderbilt-Ingram Cancer Center (VICC) to discuss their institutes molecular profiling programs with emphasis on:

·         Organization/workflow

·         Mutation detection technologies

·         Clinical protocols and reporting

·         Patient consent

In addition to the aforementioned challenges, the panel discussed further issues for developing improved science-driven criteria for determining targeted therapies including:

1)      Including pathologists into criteria development as pathology departments are usually the main repositories for specimens

2)      Developing integrated informatics systems

3)      Standardizing new target validation methodology across cancer centers

Genomics and Ethics: DNA Fragments are Products of Nature or Patentable Genes?

Curator: Aviva Lev-Ari, PhD, RN

UPDATED 6/17/2013 – OPINIONS ON COURT DECISION of 6/13/2013

Experts say court’s decision on human gene patents is a win-win

Jun 16, 2013

Jun 16, 2013 (St. Louis Post-Dispatch – McClatchy-Tribune Information Services via COMTEX News Network) — The Supreme Court ruling Thursday that naturally occurring human genes cannot be patented effectively ended the monopoly that Utah-based Myriad Genetics had on breast and ovarian cancer tests.

The news was hailed as a victory by health advocates and medical researchers, who can now not only access the genes at issue — the BRCA1 and BRCA2 — but all other patented human genes without infringement. In the wake of the decision, several other testing companies, including Quest Diagnostics, announced it would perform the tests — and at far cheaper prices than Myriad’s.

The court’s unanimous ruling, however, was mixed. It said that naturally occurring DNA could not be patented, but synthetic DNA can still be, giving patent protection advocates and Myriad a victory, too. The decision also means that methods of isolating genes still qualify for patent protection.

The Post-Dispatch interviewed experts from a broad range of fields, from medicine to law, about the court’s ruling.

Here’s what they had to say about what was at stake and what the decision could mean.

Christopher Mason

Professor of physiology, biophysics and computational biomedicine, and author of a study showing that 41 percent of the human genome is covered by patents, Cornell University

I’d say this represents a great win for genetic liberty, both for patients and for doctors. The American Medical Association said it was a big win for patients, and I couldn’t agree more — especially for breast and ovarian cancer, but for all types of cancer. This is an important cancer gene and now it’s open for study to everyone.

(Myriad) didn’t just own a test or a method, they owned anyone’s DNA as soon as it was isolated. They didn’t say we patented a series of letters, they said we patent anything that remotely looks like that, which the court correctly said is not patentable.

It would have been great to have both the patents (on natural and synthetic DNA), but of the two this is the most restrictive one — 99.9 percent of testing is done on DNA not cDNA.

Plenty of companies aren’t scared anymore. This is going to open the floodgates on new research and ideas.

Dr. Julie Margenthaler

Associate professor of surgery and breast cancer specialist, Siteman Cancer Center

This ruling has important implications for physician scientists actively engaged in genetic research. We are on the brink of significant strides in our understanding of the genetic links to many diseases.

For those of us who care for cancer patients, personalized cancer care hinges on the ability to genetically examine the pathways that result in a normal cell becoming a malignant cell. Because some companies held patents to pieces of the genome involved when whole genome sequencing is performed, there was at least some concern over patent infringement. With this ruling, we can continue to move our research forward and benefit the lives of our current and future patients.

Michael Watson

Executive director, American College of Medical Genetics and Genomics (plaintiffs in the case), and former professor of pediatrics at Washington University

It has enormous implications for labs and the public, certainly for breast cancer and for many other cancers. Since the case was settled (Thursday), at least four labs have put the test online. Prices are about half of Myriad’s — $3,500 down to $2,000 overnight.

It’s a win-win for everybody. It used to be when you had the tests done by Myriad, you couldn’t get that test confirmed by anyone else. Now the public can confirm the test and get second opinions, and that has a lot of value for patients. And I think it’ll open up the research.

There are two aspects of this that still remain open. Because 4,000 to 5,000 genes have patents on them, many people signed licensing agreements to use the gene. One of the questions is about the contract they signed. They will probably be able to challenge their contract now.

Nathan Lakey President and CEO, Orion Genomics

I think the ruling is positive because it removes a cloud of uncertainty as to where the Supreme Court stood on patents relating to gene sequences. I appreciate the thoughtfulness that went into the ruling. Justice Thomas adds a section that talks about what the ruling did not address that’s interesting. He emphasizes that method patents, or patents covering gene sequences that apply knowledge of those sequences, are patentable. I think this is what the justices sought to do, to not limit science and to not limit innovation and improvements in patient care. I think they do a markedly good job laying out the framework by which the business of science needs to consider the issue going forward as we all seek to lower the cost of care and improve outcomes.

We’re thrilled because our patents have been crafted primarily as method patents that involve naturally occurring gene sequences, and at the same time we add on to that a novel method that was not known and is quite valuable. We have biomarkers that we believe will be able to predict the risk of an individual getting colon cancer in the future, not unlike the Myriad test, but this is for colon cancer. We feel that our path forward is actually more clear and more positive given the clear line that the Supreme Court drew around what is and what isn’t patentable.

Janet S. Hendrickson

Patent attorney, specializing in chemical, pharmaceutical and food science companies, Senniger Powers law firm

They split it down the middle, and it seems to be, when looking at the commentary, that most people agree with that. They didn’t preclude the patenting of everything related to DNA, just natural DNA.

There are so many considerations and it’s hard to know what ramifications there are going to be, and what might be the best policy. It does mean that for companies that have these claims on natural DNA in their portfolio, they need to make sure they have the other range of claims for the cDNA (synthetic DNA). For companies that have past patents, it’s going to figure into those claims for those natural DNA products.

So it’s hard to tell whether it has broader implications for other things, that when you take them out of their natural milieu we thought were patentable.

Kevin Emerson Collins Professor, Washington University School of Law and patent law expert

This is going to mean one thing for patent lawyers and another thing for biotech companies. For patent lawyers, we now have a new source of business. The court hasn’t given us precise guidelines that say exactly when in other situations do we pass from something being a product of nature to a patentable invention. That’s a new frontier that patent lawyers are going to have to advise companies on.

For biotech companies it’s going to mean they pay patent lawyers a little more. Although the Myriad Genetics ruling deals with DNA, it would seem from the language of the opinion that the ruling should also apply to nongenetic, naturally occurring materials, but exactly how is yet to be determined.

A historical example that predates the Myriad controversy is the debate over the patentability of insulin in the early 20th century. A very famous lower court opinion held that isolated and purified human insulin was patentable so long as it became isolated insulin with impurities removed and took on new commercial value. I bet that case might well come out differently under the Myriad Genetics ruling. The insulin question is moot; that patent has expired. Similarly there a number of other therapeutics which are components that nature already makes that are isolated in a way they can be used in medicine but not in their natural state. Those are the kinds of things we’re going to have to grapple with.

Josh Newby-Harpole Founder, Theresa Harpole Foundation for Metastatic Breast Cancer in Alton

We have a foundation we started this year in honor of my mom. She was diagnosed over seven years ago with stage zero breast cancer. They did genetic testing and found out she had the BRCA gene. In 2010 she got diagnosed with metastatic breast cancer after she had a lump in her neck and it had spread to her bones. I needed to get tested at that point. I had testing done in Chicago and found out that I had the BRCA gene. As a male I’m lucky she had a son and not a daughter. My mom has been on different courses of treatment, and I monitor my health as well as I can, because I have a higher risk for certain kinds of cancer such as prostate and skin cancer and a higher than 3 percent chance of breast cancer.

The cost was probably over $2,000 to have the test done, and I paid close to $1,000 for it. We’re very excited about the Supreme Court ruling. I think a lot of people are hesitant to get the test done because of the cost. It’s exciting because it means possibilities. More people are going to be motivated to do research in labs to try to find a cure. Maybe they can come up with better treatment options for women because some of them will find out they have the gene and they don’t have evidence of disease. It’s something that is really getting a lot of attention right now, and the population is maybe not as aware about things like BRCA and metastatic breast cancer.

Yvette Liebesman Assistant professor of law, St. Louis University

It’s very good for research and in fact it’s very good for health care in the sense that already today a competitor for Myriad said they would run the same test for thousands less. Already we’re seeing a good thing happening that more women are going to be able to be tested for this gene. Now we’re talking about more women being aware of their health risks. Now a company that wants to develop a drug isn’t going to have to go through Myriad to isolate this gene in order to test drugs for breast cancer.

If Myriad won this case it would be like saying while a tree is made by nature, if I find a way to pick the leaves off it, the leaf is my patented product. Myriad did win in one sense, that there is a form of DNA not found in nature that is patentable. This is very logical. I think that like with most things, the people who are doomsayers will say it’s not going to have as great of an impact. The idea that now this opens up the ability to develop treatments is going to be huge.

UPDATED 6/13/2013, following the new Supreme Court Decision on 6/13/2013 to include it, below.

The Supreme Court ruled unanimously Thursday that human genes cannot be patented, a decision that could shape the future of medical and genetic research and have profound effects on pharmaceuticals and agriculture.The ruling was a split decision for Myriad Genetics Inc., which holds patents on genes that have been linked to breast and ovarian cancer.

Justice Clarence Thomas, writing for the court, said that merely isolating those specific genes — called BRCA1 and BRCA2 — was not worthy of a patent.

“Myriad found the location of the BRCA1 and BRCA2 genes, but that discovery, by itself, does not render the BRCA genes . . . patent eligible,” Thomas wrote.On the other hand, Thomas wrote, Myriad’s creation of a synthetic form of DNA — called cDNA — based on its discovery does deserve patent protection.“The lab technician creates something new when cDNA is made,” Thomas wrote.Responding to the decision, Myriad focused on the favorable cDNA ruling. “We believe the court appropriately upheld our claims on cDNA, and underscored the patent eligibility of our method claims, ensuring strong intellectual property protection for our BRACAnalysis test moving forward,” said Peter D. Meldrum, company president and chief executive. “More than 250,000 patients rely upon our BRACAnalysis test annually, and we remain focused on saving and improving peoples’ lives and lowering overall health-care costs.”DNA research is a vital component of personalized medicine. The challenge to Myriad’s patents came from scientists and doctors who said that allowing patents on genes inflated the cost of testing and hindered research.

The American Civil Liberties Union praised the high court’s ruling as a victory. “Today, the court struck down a major barrier to patient care and medical innovation,” said Sandra Park of the ACLU, which represented the groups that brought the challenge. “Because of this ruling, patients will have greater access to genetic testing, and scientists can engage in research on these genes without fear of being sued.”

The test that Myriad offers for determining whether a woman contains the genetic mutation that heightens her chance of cancer has received much attention lately after actress Angelina Jolie wrote about it in a letter to the editor to the New York Times. In the letter, Jolie revealed that she had a double mastectomy because the test showed she carried the defective gene.

v. MYRIAD GENETICS, INC., ET AL.

CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE FEDERAL CIRCUIT

No. 12–398. Argued April 15, 2013—Decided June 13, 2013

Each human gene is encoded as deoxyribonucleic acid (DNA), which takes the shape of a “double helix.” Each “cross-bar” in that helix consists of two chemically joined nucleotides. Sequences of DNA nucleotides contain the information necessary to create strings of amino acids used to build proteins in the body. The nucleotides that code for amino acids are “exons,” and those that do not are “introns.” Scientists can extract DNA from cells to isolate specific segments for study. They can also synthetically create exons-only strands of nucleotides known as composite DNA (cDNA). cDNA contains only the exons that occur in DNA, omitting the intervening introns. Respondent Myriad Genetics, Inc. (Myriad), obtained several patents after discovering the precise location and sequence of the BRCA1 and BRCA2 genes, mutations of which can dramatically increase the risk of breast and ovarian cancer. This knowledge allowed Myriad to determine the genes’ typical nucleotide sequence, which, in turn, enabled it to develop medical tests useful for detecting mutations in these genes in a particular patient to assess the patient’s cancer risk. If valid, Myriad’s patents would give it the exclusiveright to isolate an individual’s BRCA1 and BRCA2 genes, and would give Myriad the exclusive right to synthetically create BRCA cDNA. Petitioners filed suit, seeking a declaration that Myriad’s patents areinvalid under 35 U. S. C. §101. As relevant here, the District Court granted summary judgment to petitioners, concluding that Myriad’s claims were invalid because they covered products of nature. The Federal Circuit initially reversed, but on remand in light of Mayo Collaborative Services v. Prometheus Laboratories, Inc., 566 U. S. ___, the Circuit found both isolated DNA and cDNA patent eligible. 2 ASSOCIATION FOR MOLECULAR PATHOLOGY v. MYRIAD GENETICS, INC. Syllabus

Held: A naturally occurring DNA segment is a product of nature and not patent eligible merely because it has been isolated, but cDNA is patent eligible because it is not naturally occurring. Pp. 10–18. 

(a) The Patent Act permits patents to be issued to “[w]hoever invents or discovers any new and useful . . . composition of matter,” §101, but “laws of nature, natural phenomena, and abstract ideas”“ ‘are basic tools of scientific and technological work’ ” that lie beyond the domain of patent protection, Mayo, supra, at ___. The rule against patents on naturally occurring things has limits, however. Patent protection strikes a delicate balance between creating “incentives that lead to creation, invention, and discovery” and “imped[ing] the flow of information that might permit, indeed spur, invention.” Id., at ___. This standard is used to determine whether Myriad’s patents claim a “new and useful . . . composition of matter,” §101, or claim naturally occurring phenomena. Pp. 10–11. 

(b) Myriad’s DNA claim falls within the law of nature exception.Myriad’s principal contribution was uncovering the precise location and genetic sequence of the BRCA1 and BRCA2 genes. Diamond v. Chakrabarty, 447 U. S. 303, is central to the patent-eligibility inquiry whether such action was new “with markedly different characteristics from any found in nature,” id., at 310. Myriad did not create or alter either the genetic information encoded in the BCRA1 and BCRA2 genes or the genetic structure of the DNA. It found an important and useful gene, but ground breaking, innovative, or even brilliant discovery does not by itself satisfy the §101 inquiry. See Funk Brothers Seed Co. v. Kalo Inoculant Co., 333 U. S. 127. Finding the location of the BRCA1 and BRCA2 genes does not render the genes patent eligible “new . . . composition[s] of matter,” §101. Myriad’s patent descriptions highlight the problem with its claims: They detail the extensive process of discovery, but extensive effort alone isinsufficient to satisfy §101’s demands. Myriad’s claims are not saved by the fact that isolating DNA from the human genome severs the chemical bonds that bind gene molecules together. The claims are not expressed in terms of chemical composition, nor do they rely on the chemical changes resulting from the isolation of a particular DNA section. Instead, they focus on the genetic information encoded in the BRCA1 and BRCA2 genes. Finally, Myriad argues that the Patent and Trademark Office’s past practice of awarding gene patents is entitled to deference, citing J. E. M. Ag Supply, Inc. v. Pioneer Hi-Bred Int’l, Inc., 534 U. S. 124, a case where Congress had endorsed a PTO practice in subsequent legislation. There has been no such endorsement here, and the United States argued in the Federal Circuit and in this Court that isolated DNA was not patent eligible under §101. Pp. 12–16.

Syllabus

(c) cDNA is not a “product of nature,” so it is patent eligible under§101. cDNA does not present the same obstacles to patentability as naturally occurring, isolated DNA segments. Its creation results in an exons-only molecule, which is not naturally occurring. Its order of the exons may be dictated by nature, but the lab technician unquestionably creates something new when introns are removed from a DNA sequence to make cDNA. Pp. 16–17.

(d) This case, it is important to note, does not involve method claims, patents on new applications of knowledge about the BRCA1 and BRCA2 genes, or the patentability of DNA in which the order of the naturally occurring nucleotides has been altered. Pp. 17–18. 

689 F. 3d 1303, affirmed in part and reversed in part.

JUSTICE SCALIA, concurring in part and concurring in the judgment. 

I join the judgment of the Court, and all of its opinion except Part I–A and some portions of the rest of the opinion going into fine details of molecular biology. I am un-able to affirm those details on my own knowledge or even my own belief. It suffices for me to affirm, having studied the opinions below and the expert briefs presented here, that the portion of DNA isolated from its natural state sought to be patented is identical to that portion of the DNA in its natural state; and that complementary DNA (cDNA) is a synthetic creation not normally present in nature.

Evolution of the case ASSOCIATION FOR MOLECULAR PATHOLOGY ET AL. v. MYRIAD GENETICS, INC., ET AL. priot to 6/13/2013 Supreme Court decision

Curator: Aviva Lev-Ari, PhD, RN

In an amicus brief, the Broad Institute‘s Eric Lander shares his personal view of the ongoing gene patenting case between Myriad Genetics and the American Civil Liberties Union, saying that isolated DNA fragments are products of Nature.

The central issue of the case revolves around Myriad’s patents on the BRCA1 and BRCA2 genes. In a mixed ruling, the federal appeals court found that while some of the company’s methods patents may not be patentable, its BRCA1 and BRCA2 gene patents, as they concern isolated DNA fragments, are patentable items as human intervention is needed to isolate DNA.

Lander argues that that is not true, though, as the Boston Globe points out, his brief was not filed in support of either side. Isolated DNA, he says, happens all the time in nature. “It is well-accepted in the scientific community that

(a) chromosomes are constantly being broken into DNA fragments by natural biological processes that break the covalent bonds within DNA chains;

(b) these DNA fragments can be routinely found in the human body … and

(c) these fragments cover the entire human genome and, in particular, include many of the DNA fragments claimed by Myriad’s patents,” the brief says.

The US Supreme Court announced in December that it will re-hear the Myriad gene patenting case.

Late last year, the nation’s highest court said it would consider a legal challenge to patents that biotechnology company Myriad Genetics holds on breast cancer genes. Now, Eric Lander, head of the Broad Institute in Cambridge, has filed an amicus brief that he says reflects his personal opinion. Utah-based Myriad, Lander argues, has patented products of nature, and its patents are an “insurmountable barrier” to studying DNA, with serious repercussions for medical progress.

ARGUMENT
1. THE FEDERAL CIRCUIT INCORRECTLY ASSUMED, WITHOUT CITING SCIENTIFIC EVIDENCE, THAT ISOLATED DNA FRAGMENTS OF THE HUMAN GENOME DO NOT OCCUR IN NATURE, WHEN IT IS WELL-ACCEPTED IN THE SCIENTIFIC COMMUNITY THAT THEY DO
2. MYRIAD’S COMPOSITION-OF-MATTER CLAIMS ON ISOLATED FRAGMENTS OF THE GENOMIC DNA ARE INCONSISTENT WITH THIS COURT’S SECTION 101 JURISPRUDENCE BECAUSE THEY (1) ARE DIRECTED TO PREEXISTING PRODUCTS OF NATURE (2) EXCLUDE OTHERS FROM OBSERVING, CHARACTERIZING OR ANALYZING THESE PRODUCTS OF NATURE BY ANY MEANS WHATSOEVER; AND (3) CREATE AN INSURMOUNTABLE BARRIER TO SCIENTIFIC PROGRESS AND TECHNOLOGICAL INNOVATION CONCERNING THESE PRODUCTS OF NATURE
3. A NARROWLY CRAFTED DECISION BY THIS COURT WOULD NOT UNDERMINE THE BIOTECHNOLOGY INDUSTRY AND INSTEAD WOULD FOSTER INNOVATION
CONCLUSION
It is well-accepted in the scientific community that isolated DNA fragments of the human genome – including isolated DNA fragments of the BRCA1 and BRCA2 genes – are found routinely in th human body and are thus patent-ineligible products of Nature. The biotechnology industry would not be substantially affected by a narrowly crafted decision here holding that
1) fragments of human genome DNA are patent-ineligible where the claimed molecules themselves are routinely found in Nature and where the process for purification or synthesis of such molecules iS routine and
(2) cDNAs are patent-eligible.

The Supreme Court should be mindful of naturally derived products other than nucleic acids when deciding Myriad

The following contribution to our gene patenting symposium come from Susan McBee and Bryan Jones. Ms. McBee is the Chair of the Life Sciences Intellectual Property Team for Baker, Donelson, Bearman, Caldwell, and Berkowitz, P.C. Bryan Jones is a registered patent attorney in the Washington D.C. office of Baker, Donelson, Bearman, Caldwell, and Berkowitz, P.C.  

In April, the Supreme Court will hear oral argument in Association for Molecular Pathology v. Myriad, ostensibly on the question whether so-called “gene patents” satisfy 35 U.S.C. § 101.  However, Myriad is about more than whether “genes” can be patented.  It is about what types of activities justify patent protection.  Does one need to create something that is unlike anything else that has ever existed in order to justify a patent?  Or is it enough to discover something that was previously unknown, remove it from its natural environment, and show that it has a practical application?

This is a critical question to the biotechnology industry, because many biotechnological products are not novel chemical structures, but naturally occurring products.  Between 1981 and 2006, approximately forty percent of all pharmaceuticals approved for use by the FDA were a biologic, natural product, or derived from a natural product.  Moreover, for start-up biotechnology companies, patents covering such products are incredibly important, “as they are often the most crucial asset they own in a sector that is extremely research-intensive and with low imitation costs.” Strong and enforceable patents to these core products therefore are vitally important to the healthy development of the biotechnology industry.

Before the Myriad case, the Court has not had an opportunity to consider the patentability of such products.  Therefore, this case has the potential to have an enormous impact on the viability of the business model in this industry.

In Myriad, Judge Lourie and Judge Moore both found “isolated” nucleic acids to be patentable, but for different reasons.  Judge Lourie was convinced that isolated nucleic acids are patentable because isolation “breaks covalent bonds” relative to the longer native nucleic acid, thereby resulting in a new chemical entity.  Judge Moore reasoned that, if analyzed on a blank slate, she would require the product to have a “substantial new utility” relative to its natural function in order to satisfy 35 U.S.C. § 101.  While we agree that the generation of a novel chemical entity or demonstration of a new utility would be sufficient to satisfy 35 U.S.C. § 101, we do not believe these to be necessary requirements.

Consider, for example, Taq polymerase.  The inclusion of Taq into a process called polymerase chain reaction (PCR) has often been credited as being the single most important technological advance to the modern biotechnology industry.  PCR uses repeated cycles of increasing and decreasing temperatures in the presence of a polymerase to amplify a target nucleic acid.  In the original iteration of PCR, new polymerase enzyme had to be added to the reaction mixture after each heat cycle, because the high temperature permanently deactivated the enzyme.  Taq, however, is heat stable and thus does not lose activity when subjected to high temperatures.  Because of this stability, Taq only needs to be added to a PCR reaction mixture once, thus greatly reducing the costs and the time of performing the process, and permitting easy automation.  Clearly, then, the identification and characterization of this enzyme is a significant technological advance, from which the public obtains a significant benefit.  Yet the properties of Taq that make it so attractive for PCR are a consequence of its structure and function in the natural world.  Taq is naturally produced by Thermus aquaticus, a bacterium that is naturally found in hot springs.  Therefore, in nature, just like in PCR, Taq functions as a thermostable enzyme that catalyzes the amplification of a nucleic acid.  Why should this render Taq unpatentable?

The Constitution does not require a claimed compound to have a formally “new” chemical structure or new function to justify a patent.  Article I, section 8 of the Constitution authorizes patents “[t]o promote the Progress of Science and useful Arts . . . .”  As explained by the Court:

Congress may not authorize the issuance of patents whose effects are to remove existent knowledge from the public domain, or to restrict free access to materials already available.  Innovation, advancement, and things which add to the sum of useful knowledge are inherent requisites in a patent system which by constitutional command must ‘promote the Progress of useful Arts.’  This is the standard expressed in the Constitution and it may not be ignored.

Thus, the Constitution only limits patents that “remove existent knowledge from the public domain” or “restrict free access to materials already available.”  Assuming that Taq was not previously known, a claim to it in isolated form simply cannot “remove existent knowledge from the public domain.”  Because Taq naturally exists only in the context of a living organism, claiming it in “isolated” form cannot “restrict free access to” its source.  Thus, constitutional limits cannot justify a prohibition on patents covering isolated naturally occurring products.

Nor does 35 U.S.C. § 101 clearly prohibit such patents.  The statute specifically encompasses “discoveries,” so long as those discoveries relate to processes, compositions of matter, or articles of manufacture that are “new” and “useful.”  In most cases, naturally occurring products are found in very minute quantities in complex association with other molecules inside living organisms.  The act of isolating the natural product removes them from this context, thereby inevitably resulting in a composition that is materially different than anything that exists in nature.  An “isolated” natural product therefore is “new” compared to the same product in its natural state.  Its discovery thus could justify a claim under 35 U.S.C. § 101.

Finally, Supreme Court precedent does not clearly prohibit patenting of such claims.  Under the closest Supreme Court precedent, a patent that is limited to a “non-naturally occurring article of manufacture or composition of matter” satisfies 35 U.S.C. § 101.  Although it is often convenient to describe naturally occurring compounds in terms of chemical structure or nucleotide or amino acid sequence, they rarely if ever exist in nature as isolated compositions.  Rather, they are found in complex associations with other compositions, usually within living organisms.  The removal of these products from their natural context sometimes results in distinct chemical entities, such as the isolated nucleic acids in Myriad.  Other times, the result is a highly purified form of the compound, such as isolated adrenaline or purified vitamin B12.  In each case, however, the intervention of man is required to produce the “isolated” composition.  Claims directed to “isolated” natural compounds thus are limited to purely artificial, non-naturally occurring compositions of matter.  This should make them patentable, irrespective of whether they have a novel chemical structure or new utility in isolated form.

It is our sincere hope that the Court will not only find isolated nucleic acids to be patentable, but that it will do so under a rationale which allows for other naturally derived products to similarly be patentable.  In as much as a possible test can be garnered, our recommendation is to find that a naturally derived product satisfies 35 U.S.C. § 101 as long as it is claimed in a purely man-made form (and thus is “new”), and the form in which it is claimed has a practical utility disclosed in the Specification (and thus is “useful”).  This test closely aligns with the plain language of 35 U.S.C. § 101.  Challenges to the eligibility of such claims could then focus on two clear issues: (1) whether the claim encompasses the product in its natural state; and (2) whether the claim is reasonably commensurate in scope with the disclosed utility (i.e., is the claim narrowly tailored to products that possess the disclosed utility?).  This allows overly broad claims to be invalidated without resorting to a categorical ban on a broad class of subject matter.  Moreover, it would not require courts to answer the philosophical question of whether something has enough of a structural or functional change to justify a patent.

Appeals Court Affirms Isolated DNA Patents in Myriad Case

August 16, 2012

NEW YORK (GenomeWeb News) – A federal appeals court today has for a second time reversed a lower district court’s decision that isolated genes are not patentable, but it also partly affirmed the District Court’s decision that certain methods patents “comparing” or “analyzing” gene sequences may not be patentable.

The Supreme Court recently asked the US Court of Appeals for the Federal Circuit to reconsider its earlier decision in the case, The Association for Molecular Pathology v. the US Patent and Trademark Office and Myriad Genetics, in light of its ruling in another lawsuit, called Mayo Collaborative Services v. Prometheus Laboratories.

AMP v USPTO focuses on the patentability of Myriad Genetics’ claims on isolated gene sequences and diagnostic methods related to its BRACAnalysis test. In Mayo v Prometheus, the Supreme Court recently invalidated patents held by diagnostics firm Prometheus because they merely described laws of nature, and did not apply those laws of nature in a markedly different manner as to warrant a patent.

Despite the Supreme Court’s ruling in Mayo, the CAFC in a 2-1 decision maintained that although isolated gene sequences may be derived from naturally occurring substances, their isolation requires human intervention in order to make them useful in medical care and so are deserving of patent protection.

“We are very pleased with the favorable decision the Court rendered today which again confirmed that isolated DNA is patentable,” Myriad Genetics President and CEO Peter Meldrum said in a statement. “Importantly, the court agreed with Myriad that isolated DNA is a new chemical matter with important utilities which can only exist as the product of human ingenuity.”

The decision was met with disappointment by those opposing gene patenting.

“It is extremely disappointing that despite the Supreme Court’s ruling, the appeals court has failed to fully re-consider the facts of this case,” Chris Hansen, a staff attorney with the ACLU Speech, Privacy and Technology Project, said in a statement.

The case against Myriad was filed in 2009 by the Public Patent Foundation, American Civil Liberties Union, AMP, and others who claim that patents cannot cover natural phenomena and that Myriad’s patents, and others like them, will hinder genetics research and keep some people from accessing tests and second opinions.

“This ruling prevents doctors and scientists from exchanging their ideas and research freely,” Hansen added the ACLU statement today. “Human DNA is a natural entity like air or water. It does not belong to any one company.”

Myriad said again today what it has argued all along, that gene patents have not thwarted research, that the cost of its BRACAnalysis test is not prohibitive and is covered through most insurance for “appropriate” patients, and that second opinion testing is available in many US labs.

“Certainly, you could hear a collective sigh of relief from the biotech industry, as of this decision,” Jennifer Camacho, an attorney and shareholder with law firm Greenberg Traurig, told GenomeWeb Daily News today.

“Isolated DNA patents remain intact. We still have patent eligibility for isolated DNA,” Camacho said, explaining that the court’s decision to uphold the patentability of isolated DNA may be seen by the biotech industry as more important than its reading of the reach of the Prometheus decision.

“They did actually take [the Prometheus decision] into consideration,” Camacho said, adding that it did not change the judges’ analysis.

“This puts a narrow interpretation of Prometheus in the books, as being limited to the ‘laws of nature’ exclusion, she added.

Camacho told GWDN that she was struck by how similar today’s CAFC ruling was to the original. She pointed out that part of one judge’s opinion, which argued that whether some patents should or should not be awarded are policy questions that are best left to Congress, was the same language as in the first opinion.

For Myriad, the ruling provided mixed results, Goldman Sachs Investment Research analyst Isaac Ro said in a note today.

On the positive side for Myriad, the patent eligibility of its BRCA1 and BRCA2-based tests was upheld again based on its isolated DNA claims and screening method claims. But a potential negative is that the CAFC also upheld the District Court’s opinion that Myriad’s method claims for comparing DNA sequences are not eligible.

“The outcome is modestly disappointing,” Ro stated, adding that the critical question now is whether or not the Supreme Court will agree to hear the case next year.

US Supreme Court Agrees to Hear Myriad Patent Case Again

NEW YORK (GenomeWeb News) – The US Supreme Court decided on Friday to once again hear the American Civil Liberty Union’s case against Myriad Genetics challenging the firm’s patent rights related to BRCA1 and BRCA2 genes.

The decision by the court to hear the case — originally filed by ACLU, the Public Patent Foundation, the Association for Molecular Pathology and others in 2009 — comes a little more than three months after a federal appeals courtissued a mixed ruling in which it found that isolated genes are patentable, but that certain methods patents that compare or analyze gene sequences may not be.

The US Court of Appeals for the Federal Circuit issued its decision in August after the Supreme Court asked it in March to reconsider a decision rendered by the appeals court in 2011 in light of the Supreme Court’s decision in another case, Mayo Collaborative Services v. Prometheus Laboratories. In that case, the Supreme Courtinvalidated patents held by Prometheus, saying the patents merely described laws of nature but did not apply those laws of nature in a markedly different manner as to warrant a patent.

The appeals court originally ruled in July 2011 that Myriad’s patents covering isolated DNA are patentable under Section 101 of the US Patent Act, reversing a decision by the Federal District Court for the Southern District of New York that isolated DNA is not much different from gene sequences found in nature and therefore is not patentable.

This past September, ACLU and the Public Patent Foundation asked the Supreme Court to once again take up the issue of whether Myriad’s claims on genes that predict the risk of ovarian and breast cancer can be patented. ACLU and the foundation contend that Myriad’s BRCA1 and BRCA2 gene patents should be invalidated because the genes are products of nature and allowing Myriad patent protection stifles scientific research and patient access to medical care.

“Myriad did not invent human genes, and has no right to claim ownership of them just because they removed them from the body,” Daniel Ravicher, executive director of PUBPAT, said in a statement on Friday. “The government does not have the right to give a corporation the exclusive power to control what we know about our own genetic makeup.”

Myriad President and CEO Peter Meldrum said in a statement, however, that patent protection is necessary to drive technological innovation.

“Two previous decisions by the Federal Circuit Court of Appeals confirmed the patentability of our groundbreaking diagnostic test that has helped close to 1 million people learn about their hereditary cancer risk,” he said. “Myriad devoted more than 17 years and $500 million to develop its BRACAnalysis test. The discovery and development of pioneering diagnostics and therapeutics require a huge investment and our US patent system is the engine that drives this innovation.

“This case has great importance for the hundreds of millions of patients whose lives are saved and enhanced by the life science industry’s products,” he said.
