In 2011, a National Academy of Sciences report called for the creation of a "knowledge network of disease" to help researchers and doctors share information and patient data more effectively. Such a network would also allow scientists and clinicians to access data on the molecular makeup of diseases, vastly improving diagnosis and treatment. But the concept -- known as "precision medicine" -- is already raising ethical questions and concerns over patient privacy. We talk to the heads of National Institutes of Health, the Food and Drug Administration and UCSF about precision medicine, the subject of a two-day summit in San Francisco this week.
