For Rules on Creating ‘CRISPR Babies’ from Edited Embryo, Scientists Call a Do-Over

(STAT News) – The second-most shocking thing He Jiankui told the international genome editing summit in Hong Kong last November — right after announcing that twin girls had been born from embryos whose DNA he’d changed with CRISPR — was that he’d followed guidelines on embryo editing set forth by a panel of leading U.S. scientists and ethicists. That committee of the National Academies of Science, Engineering, and Medicine basically said, in 2017: If society agrees this is OK, proceed with extreme caution. He claimed he had checked all the panel’s boxes, meeting a long list of criteria that include editing only genes “convincingly demonstrated” to cause the disease, conducting “credible” animal studies first, and having “reliable oversight mechanisms.”
