A doctor who treats infertility in New York City says he has helped a couple have the first baby purposefully created with DNA from three different adults.
John Zhang of the New Hope Fertility Center in Manhattan traveled to Mexico earlier this year to perform a procedure for a couple from Jordan that enabled them to have the baby in May, according to a clinic spokesman.
Zhang performed the procedure in the hopes of helping the couple, who the clinic declined to identify, have a healthy baby. The couple had lost their first two children to Leigh syndrome, an inherited neurological disorder.
The idea of creating babies this way to help prospective parents who come from families plagued by genetic disorders has long been controversial. In February, a 12-member panel assembled by the National Academies of Sciences, Engineering and Medicine outlined a plan for how scientists could ethically pursue the research.
