In April, a San Francisco–area startup called BaseHealth announced health-management software that integrates diet, exercise, genetic tests, and medical records, then calculates a patient’s risk for more than 40 diseases—including type 2 diabetes, lung cancer, and Alzheimer’s disease—and suggests ways to lower the risk of developing them. “Genetic data is one more piece of patient care data that helps motivate and excite patients,” says Katherine Sutherland, a physician in Silicon Valley who recently began offering BaseHealth’s application to some patients. Before a patient can use BaseHealth, a doctor must upload information, such as prescription history and physiological measures like blood pressure, that would commonly be found in an electronic medical record.
