Chinese Scientist in Gene-Edited Babies Controversy Reveals Second Pregnancy

Scientist He Jiankui claims to have helped to create the world's first genetically edited babies, twin girls which were said to have been born this month; whose DNA he says he altered with powerful gene editing tools; if his claims are true this would be a profound leap of both science and ethics.

Southern University of Science and Technology, where He is an associate professor and is said to have conducted the research without the full knowledge of the university, has sealed off his lab and suspended him pending an investigation.

He Jiankui has told detractors at a conference in Hong Kong he's proud of his work.

Reaction to the claim was swift and harsh.

However they added that there were too many scientific and technical uncertainties to permit clinical trials at this stage.

He's experiment "crossed the line of morality and ethics adhered to by the academic community and was shocking and unacceptable", Xu said.

The university, according to BBC, said that He had been on unpaid leave since February.

This sort of gene editing is banned in the USA, though Deem said he worked with He on the project in China.

Gene editing is a way to rewrite DNA, the code of life, to try to supply a missing gene that is needed or disable one that is causing problems.

It's only recently been tried in adults to treat deadly diseases, and the changes are confined to that person.


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.

After the presentation, he was met with criticism and ethical questions regarding the transparency of gene editing, and it also sparked calls for global agreement as the process outpaces the ability to make new laws. They need this protection.

However, despite being a heavy investor in gene-editing, more than 120 Chinese scientists have condemned He Jiankui's work as it has dealt a massive blow to their biomedical research reputation and wrote, "It's extremely unfair to Chinese scientists who are diligent, innovative and defending the bottom line of scientific ethics... directly experimenting on human is nothing but insane... as soon as a living human is produced, no one could predict what kind of impact it will bring, as the modified inheritable substance will inevitably blend into human genome pool".

Other concerns have focused on the CCR5 gene, which scientists at the conference said is crucial to the human immune system.

Doudna is paid by the Howard Hughes Medical Institute and Zhang receives grant support from the organization, which also supports AP's Health & Science Department.

Before Mr He's talk, Dr George Daley, Harvard Medical School's dean and one of the conference organisers, warned against a backlash to gene editing because of Mr He's experiment. But based on news reports, he said, Dr. He's research was the status of a possible pregnancy of a second woman he said he had implanted with an edited embryo.

After He's findings were announced, the Chinese government ordered an "immediate investigation" into the incident.

There is no independent confirmation of what He says he did.

Nobel laureate David Baltimore called He's work irresponsible.

"It's nearly like not editing at all" if only some of certain cells were altered, because HIV infection can still occur, Church said. "I met the parents". According to the consent form, the total value of treatments and payments was approximately $40,000 - over four times the average annual wage in urban China.
