Gene-editing scientist under scrutiny by Chinese officials


WASHINGTON – The rebuke from China was fast and furious.

A Chinese scientist who claimed he helped make the world's first gene-edited babies is now under investigation by government bodies and by his own university.

He Jiankui, a 34-year-old associate professor based in the southern Chinese city of Shenzhen, said his laboratory used the powerful gene-editing tool CRISPR to alter human embryos – leading to the births of twin girls earlier this month, he said.

There is no yet independent confirmation of his claim, but scientists and regulators have been swift to condemn the experiment as unethical and unscientific.

The National Health Commission on Monday ordered local officials in Guangdong province – where Shenzhen is located – to investigate He's actions. China's state radio broadcaster, CCTV, reported Tuesday that if births are confirmed, the case will be handled "in accordance with the relevant laws and Regulations. "It's not clear if he could face possible criminal charges.

He's employer, Southern University of Science and Technology, said in a statement that he was not informed about He's human gene-editing work and has opened a survey. The school said He's research "seriously violated academic ethics and standards."

He also faces tests by the Shenzhen City Medical Ethics Expert Board and the Chinese Academy of Science's academic division.

He's research team included his former Rice University consultant, physics professor Michael Deem, who sits on the scientific advisory boards of He's two genetic companies. Rice said he has launched an investigation into Deem's involvement.

"So far the main response within China is to condemn and criticize this work," said Jing-Bao Nie, an expert on Chinese bioethics at the University of Otago in New Zealand.
