Practical genomics. Out of the lab, into practice.

Mapping individuals' genes could transform health care. A person susceptible to a certain disease could take corrective action years before onset. A doctor could become a lifelong lifestyle coach. Comparing genetic maps across populations could reveal factors that combine to cause diseases. Some hospitals are pushing forward on the genomics front despite daunting obstacles, including cost, fear of misuse of data by insurers, and an inability to share data.
