U.S. to Develop DNA Study of One Million PeoplePresident Barack Obama is proposing to spend $215 million on a “precision medicine” initiative the centerpiece of which will be a national study involving the health records and DNA of one million volunteers, administration officials said yesterday. Precision medicine refers to treatments tailored to a person’s genetic profile, an idea already transforming how doctors fight cancer and some rare diseases.  The Obama plan, including support for studies of cancer and rare disease, is part of a shift away from “one-size-fits-all” medicine, Jo Handelsman, associate director for the White House Office of Science and Technology Policy, said in a briefing yesterday. She called precision medicine “a game changer that holds the potential to revolutionize how we approach health in this country and around the world.” The White House said the largest part of the money, $130 million, would go to the National Institutes of Health in order to create a population-scale study of how peoples’ genes, environment, and lifestyle affect their health. According to Francis Collins, director of the National Institutes of Health, the study will recruit new volunteers as well as merging data from several large studies already under way. Details still need to be sorted out, said Collins, but the study could eventually involve completely decoding the genomes of hundreds of thousands of people. More
