AP - CRISPR Babies In China
A daring effort is under way to create the first children whose DNA has been tailored using gene editing.
The clinical trial documents describe a study in which CRISPR is employed to modify human embryos before they are transferred into women’s uteruses.
The scientist behind the effort, He Jiankui, did not reply to a list of questions about whether the undertaking had produced a live birth. Reached by telephone, he declined to comment.
However, data submitted as part of the trial listing shows that genetic tests have been carried out on fetuses as late as 24 weeks, or six months. It’s not known if those pregnancies were terminated, carried to term, or are ongoing.
The birth of the first genetically tailored humans would be a stunning medical achievement, for both He and China. But it will prove controversial, too. Where some see a new form of medicine that eliminates genetic disease, others see a slippery slope to enhancements, designer babies, and a new form of eugenics.
