The cost of mapping a person’s full genetic profile has been dropping quickly. Now, doctors are struggling with a new question: how to use the information to improve people’s health.

Other specialists use the process to tailor drug therapies for advanced cancer patients. The latest research focuses on how to use genome sequencing in basically healthy people, especially those who may have a family history of disease but no symptoms.
