Outrage Intensifies Over Claims of Gene-Edited Babies

December 14, 2018

(NPR) – As researchers have scrutinized the scant details made public by the scientist, He Jiankui of the Southern University of Science and Technology in Shenzhen, China, it has become clear that He actually missed precisely editing his genetic target. He tried to make a change in a gene that would protect the girls from HIV. But, at best, he may have protected only one twin from HIV, inadvertently making her genes ostensibly superior to her sister. It’s also possible the genetic changes he made may not have protected either twin at all. Perhaps more worrisome, his attempt to use the powerful gene-editing tool CRISPR appeared to create unintended mutations in their DNA that could harm their health.
