Scientists have mapped patterns of tiny DNA differences that distinguish one person from another, an achievement that will help researchers find genes that promote common illnesses such as heart disease and diabetes.
The map represents “a real sea change in how we study the genetics of disease,” said Dr. David Altshuler, a leader of the project that included more than 200 researchers from six nations.
Scientists want to find disease-related genes as a means for diagnosis, prediction and developing treatments. Such genes give clues to the biological underpinnings of disease, and so suggest strategies for developing therapies.
