China seems to confirm gene-edited babies claim

- BY MARILYNN MARCHIONE

Chinese authoritie­s appear to have confirmed a scientist’s unpublishe­d claim that he helped make the world’s first geneedited babies and that a second pregnancy is underway, and say he could face consequenc­es for his work.

China’s official Xinhua News Agency said Monday that investigat­ors in Guangdong province determined that the scientist, He Jiankui, evaded supervisio­n of his work and violated research norms because he wanted to be famous. The report said He acted alone and will be punished for any violations of the law, although it didn’t say which regulation­s he may have broken.

The scientist stunned the world in November by claiming that he had altered the DNA of twin girls at conception to try to help them resist infection with the AIDS virus. He’s work has been widely criticized as unethical because of questions about whether the participan­ts truly understood the risks. It is also considered medically dangerous because of possible harm to other genes and the DNA changes can be passed to future generation­s.

There has been no

independen­t verificati­on of his claim, first reported by The Associated Press, and it has not yet been published, although He gave details at an internatio­nal gene editing conference in Hong Kong. Some have even speculated that it could be a hoax.

But the Chinese investigat­ion appears to confirm it. The Xinhua report says the twins and those involved in the second pregnancy will remain under medical observatio­n with regular visits supervised by government health department­s.

“It does sound like they have confirmed the existence of the babies,” said Dr. Kiran Musunuru, a genetics journal

editor from the University of Pennsylvan­ia who reviewed materials He Jiankui provided at AP’s request. Given that the Chinese investigat­ion alleged ethical lapses, He’s work might not be published by a scientific journal, but “the informatio­n needs to be made available so we know exactly what was done,” Musunuru said. “It could be as simple as putting it on the web.”

The scientist, He, could not be reached for comment. A media relations person who had been acting as He’s spokesman declined comment. It’s unclear how many edited embryos remain from He’s experiment and what will become of them.
