International experts gathered at a summit in Hong Kong that opens Tuesday will discuss how gene editing should be regulated, as a mainland scientist claimed he had helped create the world’s first genetically edited babies.

The Second International Summit on Human Genome Editing is expected to come up with a formal statement on gene editing at the close of the meeting on Thursday at the University of Hong Kong.

Robin Lovell-Badge, a member of the organising committee, said the major focus of the summit was “to talk about what’s acceptable, what’s not acceptable, how things should be regulated” in gene editing.

This comes as He Jiankui of the Southern University of Science and Technology in Shenzhen told Associated Press that twin girls, whose father is a HIV carrier, were born earlier this month after He edited their embryos to remove the gene critical to enabling many forms of the virus to infect cells.

While He’s claim has yet to be verified by his peers, he will be one of the speakers at the summit on Wednesday, when he is expected to talk about human embryo editing.

I don’t expect any science fiction-like future where we have whole populations altered; it’s totally unrealistic

The summit is co-organised by the Academy of Sciences of Hong Kong, the Royal Society, the US National Academy of Sciences and the US National Academy of Medicine.
