University of Washington, Fred Hutchinson Cancer Research Center to Coordinate NHGRI Disease Studies
News Sep 06, 2007
The University of Washington and Fred Hutchinson Cancer Research Center have been awarded a four-year $4.8 million contract by the National Human Genome Research Institute (NHGRI) of the National Institutes of Health to coordinate activities for several whole-genome studies of human disease.
The new coordinating center will provide statistical and data-management advice and services to a number of specific disease studies across the United States. The studies will compare the genetic profiles of individuals with a certain disease to the profiles of healthy people to determine the location of the genes that contribute to the disease. The disease studies include:
• International Consortium to Identify Genes and Interactions Controlling Oral Clefts (Johns Hopkins University)
• Study of Addiction: Genetics and Environment (Washington University School of Medicine)
• Genome-wide Association for Gene-environment Interaction Effects Influencing Coronary Heart Disease (University of Texas Health Science Center)
• A Genome-wide Association in a Population-based Lung Cancer Study (National Cancer Institute)
• Genes and Environment Initiatives in Type 2 Diabetes (Harvard University)
• Genome-wide Association Mapping: Maternal Metabolism-birth Weight Interactions (Northwestern University)
• Dental Caries (Tooth Decay): Whole Genome Association and Gene x Environment Studies (University of Pittsburgh)
• Genome-wide Association Studies of Prematurity and Its Complications (University of Iowa)
"While there have been numerous individual studies at the UW and the Hutchinson Center, this is the first time we've coordinated multiple whole-genome association studies across the country at one time," said Dr. Bruce Weir, chair of the UW Department of Biostatistics and a member of the Public Health Sciences Division at Fred Hutchinson Cancer Research Center.
Weir, who has experience in developing statistical methodology for genetic data, is one of three principal investigators who will be leading the new coordinating center. Joining him are Dr. Lon Cardon, co-director of the Computational Biology Program and member of the Human Biology Division at Fred Hutchinson Cancer Research Center and UW professor of biostatistics, and Dr. Richard Kronmal, director of the UW Collaborative Health Studies Coordinating Center and UW professor of biostatistics, who has managed a number of similar multi-site studies. The coordinating center will involve additional faculty from the UW departments of biostatistics, epidemiology and genome sciences.
"This is a first step in determining the genetic basis of disease and is necessary for the development of therapies and eventual cures," said Cardon, who recently led the statistical analysis of whole-genome studies for several diseases for the Wellcome Trust in the UK, the largest study to date of the genetics behind common diseases such as diabetes, rheumatoid arthritis and coronary heart disease.
Weir said the whole-genome association studies are possible because of the success of the Human Genome Project and the more recent international HapMap study of human genetic variation in several human populations, which explored how genes affect health, disease, and responses to drugs and environmental factors.
Molecular biologists long thought that domains in the genome’s 3D organization control how genes are expressed. After studying highly rearranged chromosomes in fruit flies, researchers now reveal that while this is the case for some genes, their results challenge the generality of this for many others.READ MORE
