Why I regret using 23andMe: I gave up my DNA just to find out I’m British; The Guardian, November 30, 2024

, The Guardian; Why I regret using 23andMe: I gave up my DNA just to find out I’m British

"With the future of 23andMe in peril, the overarching question among previous customers now is what will happen to the data that has already been collected. Leuenberger noted that by entering DNA into a database, users sacrifice not only their own privacy but that of blood relatives. Because an individual’s DNA is similar in structure to that of their relatives, information about others can be gleaned from one person’s sample. This is especially pronounced with the rise of open-access DNA sites like GEDMatch, on which users can upload genetic data that can be compared to other samples. A consumer genealogy test contributed to the identification of serial killer Joseph James DeAngelo.

“What is ethically tricky with genetic data is that it’s not just about self-knowledge – it’s also knowledge about all of your relatives,” Leuenberger said. “Morally speaking, it is not necessarily information that is yours to give – and this risk is exacerbated if this company goes down and the fate of the data becomes more perilous.”"
