Lulu And Nana, First Gene-Edited Babies

A Chinese researcher who claims to have created the first gene-edited babies, He Jiankui of the Southern University of Science and Technology (SUST), in Shenzhen, is now facing investigation over whether the experiment broke Chinese laws or regulations. The children have their genomes modified to make them resistant to HIV.

He, who led that effort, later released a video statement in which he said that healthy twin girls, Lulu and Nana, had been born “a few weeks ago.”

He said the girls had been conceived using In vitro fertilization (IVF) but that his team had added “a little protein and some information” to the fertilized eggs. That was a reference to the ingredients of CRISPR, the gene-editing technology he apparently employed to delete a gene called CCR5.

The claim set off a wave of criticism in China and abroad from experts who said the experiment created unacceptable risks for a questionable medical purpose. Feng Zhang, one of the inventors of CRISPR, called for a moratorium on its use in editing embryos for IVF procedures.

Documents connected to the trial named the study’s sponsors as He along with Jinzhou Qin and said it was approved by the ethics committee of HarMoniCare Shenzhen Women and Children’s Hospital.
