He had told a human genome forum in Hong Kong that there had been "another potential pregnancy" involving a second couple. 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.
Soon after the details of the investigation came to light on Monday, He's employer, the Southern University of Science and Technology, announced it was firing the disgraced scientist - but unemployment might be the least of He's worries right now.
SUSTech said in a statement Monday it had terminated the researcher's employment after earlier saying He's work had "seriously violated academic ethics". Instead, he was widely denounced for crossing every line, scientifically and ethically, opening up a Pandora's box to a world where "designer babies" were suddenly a reality.
Editing the genes of embryos intended for pregnancy is banned in many countries, including the United States.
The commission added that the scientist has conducted the work "In pursuit of personal fame and fortune, with self-raised funds and deliberate evasion of supervision and private recruitment of related personnel".
The investigation confirmed the woman was still pregnant, Xinhua said.
Officials said the researcher and those found guilty of assisting him would be penalised and that the babies and the pregnant volunteer would be placed under medical observation. It is also considered medically unsafe because of possible harm to other genes and the DNA changes can be passed to future generations.
He had "privately" organized a project team that included foreign staff and used "technology of uncertain safety and effectiveness" for illegal human embryo gene-editing, it said.
Neither He nor a representative could be reached for comment on January 21.
"This behavior seriously violates ethics and the integrity of scientific research, is in serious violation of relevant national regulations and creates a pernicious influence at home and overseas", the report of the Guangdong province's investigation said. "I do hope that a more complete report will be issued including relevant data and procedures that were followed", Baltimore says. 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. The hospital confirmed that two of the doctors named in He's documents work at the hospital and suggested that an internal investigation was underway.
A week or so after the news broke of He's work, "he was calm, he was thoughtful", and "was thinking about what he should have done differently", Hurlbut said. According to news reports, He's movements have been restricted since he returned to Shenzhen, with guards outside his apartment on the university campus, but he has communicated with colleagues.
