The National Institutes of Health this week named a working group that will seek public input on the design of a research network to advance President Obama’s Precision Medicine Initiative. The initiative calls for building a network of about 1 million volunteers who would share their biological, environmental, lifestyle and behavioral information with qualified researchers in a way that protects their privacy, with the goal of advancing a personalized approach to disease prevention and treatment. The working group will provide information about opportunities for public input at http://www.nih.gov/precisionmedicine.
