A Genetic Study Using 23andMe Data Finds Link Between Schizophrenia and Cannabis Use

There’s evidence of a connection between cannabis use and schizophrenia, but it’s unclear whether the drug leads to the disorder, or vice versa. A new study published today, which relies partly on genetic data from 23andMe volunteers, might offer a little clarity on that link. It found that people genetically at risk of schizophrenia are also more likely to start smoking marijuana, suggesting the disorder itself might cause cannabis use in some people. Read More >>

23AndMe Accuses Ancestry.Com of Patent Infringement and False Advertising

23andMe CEO Compares DNA Tests to at-Home Pregnancy Tests, but It’s Not That Simple

In a provocative opinion published Monday in STAT, 23andMe CEO Anne Wojcicki argues that home DNA test customers don’t need experts to help them interpret genetic health risk reports. Wojcicki compares her company’s health reports, which tell people whether they are at risk of developing certain diseases, to at-home pregnancy tests. Read More >>

How DNA Testing Botched My Family’s Heritage, And Probably Yours, Too

My grandfather was caramel-skinned with black eyes and thick, dark hair, and until he discovered that he was adopted, he had no reason to suspect that he was not the son of two poor Mexicans as he’d always been told. When he found his adoption papers, according to family lore, he pestered the nuns at the Dallas, Texas orphanage where he had lived as an infant for the name of his birth mother. Name in hand, at 10 years old, he hopped a bus to Pennsylvania, met his birth mother, and found out that he was actually Syrian. Read More >>

The US Just Greenlit the First Consumer DNA Tests for Disease Risk

At times, DNA testing can feel more like horoscopes than science. In many cases, we just don’t know enough about a gene to say what it means for our health. For this reason, the US Food and Drug Administration has sought to protect consumers by preventing DNA testing companies from telling them whether or not they’re are at risk for a certain disease. Until now. Read More >>
