A Chinese researcher claims he helped make the world's first genetically
edited babies - twin girls whose DNA he said he altered with a powerful new
tool capable of rewriting the very blueprint of life.
If true, it would be a profound leap of science and ethics.
A US scientist said he took part in the work in China, but this kind of gene
editing is banned in the United States because the DNA changes can pass to
future generations and it risks harming other genes.
Many mainstream scientists think it's too unsafe to try, and some denounced
the Chinese report as human experimentation.
The researcher, He Jiankui of Shenzhen, said he altered embryos for seven
couples during fertility treatments, with one pregnancy resulting thus far.
He said his goal was not to cure or prevent an inherited disease, but to try
to bestow a trait that few people naturally have - an ability to resist
possible future infection with HIV, the Aids virus.
He said the parents involved declined to be identified or interviewed, and
he would not say where they live or where the work was done.
There is no independent confirmation of He's claim, and it has not been
published in a journal, where it would be vetted by other experts. He
revealed it on Monday in Hong Kong to one of the organisers of an
international conference on gene editing that is set to begin on Tuesday,
and earlier in interviews with The Associated Press.
"I feel a strong responsibility that it's not just to make a first, but also
make it an example," He said. "Society will decide what to do next" in
terms of allowing or forbidding such science. | D********d
