U.S. Wants to Analyze DNA from 1 Million People

The United States has proposed analyzing genetic information from more than 1 million American volunteers as part of a new initiative to understand human disease and develop medicines targeted to an individual's genetic make-up. At the heart of the "precision medicine" initiative, announced on Friday by President Barack Obama, is the creation of a pool of people - healthy and ill, men and women, old and young - who would be studied to learn how genetic variants affect health and disease.
