What Do You Think of Home Genetic Testing?

April 03, 2019

The personal genetics company 23andMe recently began offering its customers a new report informing them of their likelihood of developing type 2 diabetes.

The type 2 diabetes risk score has just been added to the company's Health & Ancestry service, which costs $199 and also provides information on genetic risks for some cancers, familial hypercholesterolemia, celiac disease, and some forms of dementia and Parkinson disease, among other conditions.

Clinical genetic tests sold directly to consumers have proliferated rapidly as DNA sequencing costs have plummeted. Approximately 75,000 genetic tests are currently on the market, with an average of 10 more added each day, according to a Health Affairs analysis. However, some experts are concerned that home test kits oversimplify genetic risk scores, delivering ambiguous results that often aren't actionable or don't take into account how lifestyle can also affect disease risk.
