Chinese scientists have announced the world’s first genetic change in babies. Twin girls received a modification that should make them resistant to certain viruses and diseases – for example, HIV.
It is known that the CCR5 gene has undergone modifications, so that the twins should be immune to the human immunodeficiency virus, cholera and smallpox. The modifications carried the embryos of seven pairs, and in one case the woman became pregnant. At the moment, this work is not described in any scientific journal and, in fact, it has no evidence. Experts plan to disclose all the information at the summit, which will be held November 27-29.
Such operations are prohibited in the UK, the United States and several other countries – it is believed that this will lead to serious ethical dilemmas.
