Introduction
Direct-to-consumer genetic testing, introduced in 2000, has seen explosive growth in recent years. In 2018, as many people purchased the testing kits as in all previous years combined. Companies such as Ancestry, FamilyTreeDNA and 23andMe provide genealogy information to consumers, and 23andMe also analyzes users' genetic risk for 12 diseases and health conditions. But critics say reports produced by the testing companies can be inaccurate, misleading and vulnerable to hacking. Others complain that government oversight is too weak to prevent genetic information from being used to discriminate against consumers or violate the privacy of relatives of people who submit their DNA for testing. Privacy concerns have grown especially acute after law enforcement officials began using some testing companies, such as GEDmatch and FamilyTreeDNA, to try to solve crimes. Testing companies defend the accuracy of their work and their privacy and security policies. They and their supporters, including some geneticists, say consumers have a right to their genetic information and that such data, stripped of identifying information, can help researchers find treatments for diseases.
Randall Lorenz, of Reno, Nev., and Jerica Starkweather, of Emmett, Idaho, realized they may be close relatives after Lorenz, who learned late in life that he had been adopted as a baby, took a direct-to-consumer genetic test. He holds up a photo of Starkweather's mother, who could be his biological sister or cousin. By the end of 2018, more than 26 million people had used consumer genetic tests to learn more about their ancestry and health risks. (AP Photo/Idaho Statesman/Darin Oswald)
