HONG KONG -- The Chinese geneticist who says he has produced the world's first genetically edited children revealed that there was a second potential pregnancy on Wednesday, as he faced an outcry from international scientists over the ethics and safety of his research.
The twin girls, whose basic genetic information was altered to protect them from inheriting HIV from their father, are healthy and will be observed over the next 18 years, He Jiankui told the second Human Genome Editing Summit in Hong Kong.
