China orders probe into first ‘gene-edited babies’

Al Jazeera  

Scientists denounce claims by Chinese geneticist as concerns are raised about its safety and ethics. We still might have a glimmer of hope to close it before it's too late by Scientists say in an open letter The government’s medical ethics committee in Shenzhen said it was investigating the case, as was the Guangdong provincial health commission, according to Southern Metropolis Daily, a state media outlet. China’s Genetics Society and the Chinese Society for Stem Cell Research said in a statement that the geneticist had acted as an “individual” and his work posed “tremendous safety risks for the research subjects”. The Shenzhen Harmonicare Hospital, listed on China’s online clinical trial registry as having given ethical approval for He’s experiment, denied having ever taken part in any clinical operations relating to “gene-edited babies”. ‘Very shocked’ The signatures on the online form were suspected of having been forged and “no relevant meeting of the Medical Ethics Committee of the hospital in fact took place”, Hong Kong-listed Harmonicare Medical Holdings said in a statement.
