Ed Cara, Gizmodo; Consumer DNA Testing May Be the Biggest Health Scam of the Decade

"This test, as well as many of those offered by the hundreds of big and small DNA testing companies on the market, illustrates the uncertainty of personalized consumer genetics.

The bet that companies like 23andMe are making is that they can untangle this mess and translate their results back to people in a way that won’t cross the line into deceptive marketing while still convincing their customers they truly matter. Other companies have teamed up with outside labs and doctors to look over customers’ genes and have hired genetic counselors to go over their results, which might place them on safer legal and medical ground. But it still raises the question of whether people will benefit from the information they get. And because our knowledge of the relationship between genes and health is constantly changing, it’s very much possible the DNA test you take in 2020 will tell you a totally different story by 2030."
