The fight to reunite immigrant families took a genetic twist this week as tensions increased over detained children. The same consumer DNA testing kits that trace ancestry and offer genetic risk assessments were proposed as a way to reunite families separated at the border. But the idea created its own minor furor — for one, the fact that the government would even need DNA tests to match a detained child to a parent. Second, the fear over privacy and security risks.

“We shouldn’t be in this position at all,” said Arthur Caplan, head of medical ethics at the New York University School of Medicine. “The kids should not have to do this genetic backfill.”
