SEATTLE — Sept. 4, 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.
Announced today, this 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:
"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 new 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.
Despite extensive research for more than a decade, the genetic basis of common human diseases remains largely unknown. Yet, scientists believe the identification of genes, variants and pathways involved in particular diseases offer a potential route to new therapies, improved diagnosis and better disease prevention. While previous studies of the human genome have focused on genes, these whole-genome association studies will provide insight into the non-gene sequences making up 98 percent of the genome. Some of these sequences are so-called "functional elements" that contain instructions for switching genes on or off, or control how DNA is packaged and replicated within a human cell. Researchers believe these DNA sequences may play an important role in some diseases.
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.
Cardon said the recent Wellcome Trust study provides another powerful resource for human-genetics research.
"The recent discovery of 21 new disease gene associations from the Wellcome Trust Case Control Consortium offers great hope for success from these new NHGRI studies," Cardon said.
