Christina Larson writing for the AP:
A Chinese researcher claims that he helped make the world’s first genetically edited babies — twin girls born this month whose DNA he said he altered with a powerful new tool capable of rewriting the very blueprint of life.
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.
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 Monday in Hong Kong to one of the organizers of an international conference on gene editing that is set to begin Tuesday, and earlier in exclusive 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 told the AP. “Society will decide what to do next” in terms of allowing or forbidding such science.
Cool, great, but I feel real story for me though lies in the execution of the experiment.
Several scientists reviewed materials that He provided to the AP and said tests so far are insufficient to say the editing worked or to rule out harm.
They also noted evidence that the editing was incomplete and that at least one twin appears to be a patchwork of cells with various changes.
There also are questions about the way He said he proceeded. He gave official notice of his work long after he said he started it — on Nov. 8, on a Chinese registry of clinical trials.
It’s unclear whether participants fully understood the purpose and potential risks and benefits. For example, consent forms called the project an “AIDS vaccine development” program.
The Rice scientist, Deem, said he was present in China when potential participants gave their consent and that he “absolutely” thinks they were able to understand the risks. The study participants are not ethicists, He said, but “are as much authorities on what is correct and what is wrong because it’s their life on the line.” Deem said he worked with He on vaccine research at Rice and considers the gene editing similar to a vaccine.
“That might be a layman’s way of describing it,” he said.
Both men are physics experts with no experience running human clinical trials.
The Chinese scientist, He, said he personally made the goals clear and told participants that embryo gene editing has never been tried before and carries risks. He said he also would provide insurance coverage for any children conceived through the project and plans medical follow-up until the children are 18 and longer if they agree once they’re adults.
He sought and received approval for his project from Shenzhen Harmonicare Women’s and Children’s Hospital, which is not one of the four hospitals that He said provided embryos for his research or the pregnancy attempts.
Some staff at some of the other hospitals were kept in the dark about the nature of the research, which He and Deem said was done to keep some participants’ HIV infection from being disclosed.
The study participants are not ethicists, He said, but “are as much authorities on what is correct and what is wrong because it’s their life on the line.”
Pretty remarkable on multiple levels. Edited genes “successfully” but at a major cost ethically.
