Although he still hasn't published any real evidence, scientists across the world were quick to condemn the ethically dubious claims, describing the experiment as "deeply concerning", "shocking", and "monstrous".
He Jiankui, a Chinese researcher, speaks during the Human Genome Editing Conference in Hong Kong, on Wednesday.
In a presentation at a genetic science conference in Hong Kong, He expressed pride at successfully creating what he claims are the first genetically modified babies.
"They need this protection since a vaccine is not available", He said. We only found out about it after it happened and after the children were born. He said he recruited the couples from an "HIV AIDS volunteer group".
"The volunteers were informed of the risk posed by the existence of one potential off-target and they chose to implant", he said.
He spoke after Harvard Medical School Dean George Daley alluded to He's claims as "missteps" that he anxious might set back a highly promising field of research.
"I disagree with the notion of stepping out of the general consensus of the scientific community", Hurlbut said. The researcher said he believes the technology can help families and that it is his duty to develop the technology and then let society decide what to do with it. Both cause tremendous suffering, are hard to treat effectively, and in rare cases are certain to be passed to any biological children, says Harvard Medical School Dean George Daley, a stem cell scientist. "I hope we just don't stick our heads in the sand". The parents of the allegedly gene-edited babies declined to be interviewed or identified.
Gene editing is banned in most countries, including China.
Daley, for his part, says he was surprised to hear that He knew about the brain research.
Gene editing could potentially help avoid heritable diseases by deleting or changing troublesome coding in embryos. Scientists have long searched for ways to block this pathway to protect people from HIV.
Genetic editing, the subject of Kazuo Ishiguro's 2005 dystopian novel Never Let Me Go, has seized the imagination - and fear - of humans for decades.
He is now facing investigation by a local medical ethics board to see whether his experiment broke Chinese laws or regulations.
The National Health Commission said on Monday that it was "highly concerned" and had ordered provincial health officials "to immediately investigate and clarify the matter".
It's a technology that lets scientists alter the DNA of living cells - from plants, animals, even humans - more precisely than ever before.
China is a major scientific power. Another is that it could open the door to "designer babies" - children that are modified for nonmedical reasons, such as to be taller, stronger or smarter. Additionally, Southern University of Science and Technology, the university where Dr.
"I would hope that the global bodies that have stated quite firmly up until this point that we would not want this to happen would still stay firm regardless of someone going rogue", she said.
