A Chinese scientist recently said he had the first genetically modified children in the world and caused a global storm. If it is true – the scientist still does not publish data to confirm it – his actions would be a serious violation of international scientific conventions. Although genetic modification promises to be able to repair dangerous mutations that cause disease and treats certain health conditions, there are many security and ethical concerns about human embryo modification.
We will also answer some of the many questions that turn around this event.
Scientist He Jiankui said he used the genetic modification method of Crispr to change the gene in human embryos to later implant embryos into the womb of a woman who gave birth to twins in November.
