Witness appearing before the Senate Subcommittee on Labor-HHS-Education Appropriations
Alan E. Guttmacher, M.D., Acting Director
National Human Genome Research Institute
I am pleased to present the President's Fiscal Year (FY) 2010 Budget request for the National Human Genome Research Institute (NHGRI) of the National Institutes of Health. The FY 2010 budget includes $509,594,000, which is $7,227,000 more than the FY 2009 appropriation of $502,367,000.
NHGRI's budget request and its research projects are consistent with the President's multi-year commitment for Cancer .
The Nation's previous investments in the Human Genome Project (HGP) and the International HapMap Project have moved research forward into many diseases with unprecedented speed. HapMap-enabled genome-wide association studies (GWAS) identify a stunning number — over 130 in 2008 alone — of genetic factors associated with major causes of morbidity and mortality in the United States, such as autism, diabetes, cardiovascular disease, lung and prostate cancer, and inflammatory bowel disease. Identification of gene variants associated with disease raises the possibility of using genetic testing, in combination with family history information, to identify susceptible, pre-symptomatic subjects for screening and preventive therapies. It also provides key new understanding of the gene-environment interactions and biological pathways that lead to disease, thus providing new insights into treatment and prevention.
Initiated in FY 2007, the Cancer Genome Atlas (TCGA) is a pilot project, jointly supported and led by the NHGRI and the National Cancer Institute (NCI) that applies a comprehensive, large-scale genomic analysis approach to cancer research. TCGA is designed to develop and test the complex scientific and technological approaches needed to identify the mutations and other genomic changes associated with various types of cancer. Three NHGRI-supported sequencing centers provide genomic sequencing capability for the TCGA. In FY 2008, the first major results of this pilot project were obtained for the most common form of brain cancer, glioblastoma multiforme (GBM). Another very exciting result was an unexpected observation that points to a potential mechanism of resistance to a common chemotherapy drug used for brain cancer. These first results from the TCGA pilot project represent an exciting indication of the value of the multi-dimensional analysis of the molecular characteristics in human cancer.In the next one to two years, the focus of TCGA will be on two other common cancers, squamous cell lung cancer and ovarian cancer, as well as further analysis of glioblastoma (brain cancer), as well as potential scale up to deal with many other forms of cancer.
The NHGRI's medical sequencing program aims to drive continued technology improvement (lowering the cost of genome sequencing) and to produce data useful to biomedical research. Seven studies are currently underway to identify the genes responsible for several relatively rare, "single-gene" diseases and to survey the range of gene variants that contribute to certain common diseases. In FY 2008, a number of medical sequencing projects were initiated: 1) Sequencing the genomic regions identified in genome-wide association studies as containing genetic components underlying common diseases, such as diabetes, breast cancer, schizophrenia, or Crohn's disease; 2) Sequencing the genomes of important human pathogens, such as those that cause malaria and sleeping sickness, and their invertebrate vectors (in collaboration with the National Institute of Allergy and Infectious Disease (NIAID); and 3) The Cancer Genome Atlas project.
In addition to basic research underway to support medical applications of genomics, two clinical genomics initiatives launched in FY 2007 are now in full stride. The first, ClinSeq, is a pilot study aimed at developing technological and procedural approaches to facilitate large-scale medical sequencing in a clinical research setting. The second, the Multiplex Initiative, is a study intended to provide genetic susceptibility testing for several common health conditions, such as cardiovascular disease and osteoporosis, to evaluate patients' reactions to the testing and receipt of results.
The 1000 Genomes Project builds on the human haplotype map developed by the International HapMap Project to produce a much more comprehensive view of genomic variation. In fact, it aims to find almost all the variants in the genome, including those that contribute to disease risk. The 1000 Genomes Project will map not only the single-letter differences in people's DNA, called single nucleotide polymorphisms (SNPs), but also will produce a high-resolution map of larger differences in genome structure called structural variants, which are rearrangements, insertions, deletions, or duplications of DNA segments. The importance of these structural variants has become increasingly clear from surveys completed in the past 18 months that demonstrate that differences in genome structure may play a role in susceptibility to such conditions as mental retardation and autism.
The project includes large-scale implementation of several new sequencing platforms to capitalize on the cost reductions emerging from evolving technologies, described in the journal Nature Biotechnology in October 2008. Using standard DNA sequencing strategies, the effort would likely cost more than $500 million. However, the cost of the project is expected to be far lower to the program, — $30 million to $50 million — due to the project's pioneering implementation of new technologies .
Currently, 197 genomes are either in the pipeline or have been completed by the NHGRI-supported large-scale sequencing centers, which are world leaders, renowned for their cost effective and high quality work. Completed in FY2009, the most recent study of a cow was an important development in agriculture that may lead to higher quality beef and milk production and possibly lower carbon dioxide emissions. Ongoing sequencing targets include several non-human primates, mammals, fungi, and multiple strains of yeast.
The NHGRI's continuing commitment to the development of innovative sequencing technologies, which reduces the cost and increases the speed of DNA sequencing, fuels the swift pace of genomic discoveries. In the past year, several groups have demonstrated the ability to work with individual DNA strands and read individual DNA bases. These two breakthroughs are being combined to deliver the ability to sequence DNA isolated directly from cells without any processing apart from purification. This is one technology with promise to achieve the goal of sequencing a genome for $1000 by 2014, NHGRI's original goal.
The NHGRI supports research to identify and characterize the function of all parts of our genome and to understand their biological relevance. Efforts to uncover functional elements are not limited to the human genome, since understanding the genomes of other, "model," organisms also can give insight into the structure and function of the human genome.
Following a successful pilot project, the NHGRI implemented a full-scale ENCyclopedia of DNA Elements (ENCODE) Project in FY 2007 to examine the entire human genome for sequence-based functional elements. Concurrently, the NHGRI initiated modENCODE, which has similar goals for the analysis of the genomes of two important model organisms. This program will take advantage of the small, more manageable genomes of these organisms to unlock the function of the many genes they share with humans.
The NHGRI supports six Centers of Excellence in Ethical, Legal, and Social Implications (ELSI) Research. The Centers focus on issues surrounding large-scale genomics research and emerging genetic technologies. The NHGRI continues to support ELSI research as a core aspect of our research portfolio in an effort to anticipate and address the societal issues that will continue to arise as we learn ever more about the human genome and its contributions to human health and disease.
The NHGRI recently began two new programs to harness genomic knowledge and technology to help patients whose needs are not met by existing scientific and medical programs. Launched in 2008, the Undiagnosed Diseases Program (UDP), jointly led by the NHGRI, the NIH Clinical Center, and the Office of Rare Diseases Research, focuses on the most puzzling medical cases referred to the NIH by physicians across the nation. The NIH Therapeutics for Rare and Neglected Diseases (TRND) Program, launched in FY 2009, builds upon the technology and strategies of high-throughput genomics to identify and shepherd novel therapeutics for diseases where the risks of failure are currently too high for the private sector, but the human need is too great to ignore. These conditions by definition either occur in fewer than 200,000 Americans or in the developing world, limiting the profit motive for industry. UDP and TRND exemplify how the country can leverage the advances funded and developed by the NHGRI and the NIH to drive the development of more personalized, predictive, pre-emptive, and participatory diagnostic and therapeutic options, improving health outcomes for all Americans.
