If each gene is a chapter in the body’s instruction manual, clinical tests read every letter in that chapter hundreds to thousands of times, Tandy-Connor says. To connect with international relatives, go with MyHeritage. A clinical lab checked worrisome results that people received from consumer DNA testing companies. “I’m not ready to do that yet,” Diamond says. The errors were in the raw data. Just freak yourself out and walk away?” Not likely. The problem was, 40 percent of the harmful variants were false positives, the researchers reported March 22 in Genetics in Medicine. “Uninterpreted raw genotype data, including data that are not used in 23andMe reports, has undergone a general quality review. Your genes interact with your diet and lifestyle to influence your susceptibility to many common diseases such as diabetes, PCOS, and migraines.

Wang wasn’t surprised that not everyone brought their results to their doctors. “SNPs cannot tell you — no amount of genetic information, actually, can tell you — what the state of your DNA methylation is,” Estep says. “They talk about early detection, but this was super early. The company did comprehensive testing of the supposedly faulty genes. For the most genetic disease risk and carrier status reports, consider 23andMe. Some consumers went straight to genetic counselors. The results misstated that the people carried the variant when they actually didn’t. Results from one of them, 23andMe, hit her with an entirely different kind of life-changing knowledge: a high risk for breast cancer.

While this is technically true, it does come with some stipulations. “There’s a sort of underworld that’s been going on since the FDA stopped 23andMe from interpreting these results and giving them out to people,” Schlager says. Those data report only a few genetic spelling variations. Those raw data consist of a list of spots, known as SNPs (pronounced “snips”), where customers’ DNA varies. Diamond got her health-related results in 2013, just before the U.S. Food and Drug Administration told 23andMe to stop giving consumers health information. So far, very few of the third-party analysis services are set up to process data from the entire genetic instruction book, or genome. Take it to a genetic counselor or some other genetic professional,” she says. About 72 percent of women who carry a cancer-associated variant in the BRCA1 gene and 69 percent of women with a harmful BRCA2 variant will develop breast cancer by age 80, researchers reported last year in JAMA. Molecular Genetics & Genomic Medicine. Those people who did tell their doctors about their results weren’t always happy with the responses. She and colleagues examined test results of 49 people who received worrisome reports based on raw data generated by direct-to-consumer genetic testing companies between January 2014 and December 2016. “To say there are 40 percent false positives may dissuade people — people who are really carrying mutations — from having these things clinically checked out,” Lennon says.
