Genome-edited baby claim provokes international outcry

A Chinese scientist claims that he has helped make the world's first genome-edited babies — twin girls who were born this month. The announcement has provoked shock, and some outrage, among scientists around the world.

He Jiankui, a genome-editing researcher from the Southern University of Science and Technology of China in Shenzhen, says that he implanted into a woman an embryo that had been edited to disable the genetic pathway that allows a cell to be infected with HIV.

In a video posted to YouTube, He says the girls are healthy and now at home with their parents. Genome sequencing of their DNA has shown that the editing worked, and only altered the gene they targeted, he says.

The scientist's claims have not been verified through independent genome testing or published in a peer-reviewed journal. But, if true, the birth would represent a significant — and controversial — leap in the use of genome-editing. So far these tools have only be used in embryos for research, often to investigate the benefit of using them to eliminate disease-causing mutations from the human germline. But reports of off-target effects in some studies have raised significant safety concerns.

Documents posted on China's clinical trial registry show that He used the ubiquitous CRISPR-Cas9 genome-editing tool to disable a gene called CCR5, which forms a protein that allows HIV to enter a cell. Genome-editing scientist Fyodor Urnov was asked to review documents that described DNA sequence analysis of human embryos and fetuses gene-edited at the CCR5 locus for an article in MIT Technology Review. "The data I reviewed are consistent with the fact that the editing has, in fact, taken place," says Urnov, from the Altius Institute for Biomedical Sciences in Seattle. But he says the only way to tell if the children's genomes have been edited is to independently test their DNA.

The Chinese university where He is an associate professor issued a statement saying that it had been unaware of his research project and that He had been on leave without pay since February, Reuters reported. The work is a "serious violation of academic ethics and standards," Southern University of Science and Technology in Shenzhen said in the statement. The university said it would immediately launch an investigation.

Update: Professor He Jiankui has defended his human genome editing project at the Human Genome Editing Summit at the University of Hong Kong. Although the project has been halted, Jiankui claimed that there was potentially a second pregnancy (and a third genome-edited baby) on the way. Jiankui also said that results have been submitted for peer review, although he did not name a journal. Eight couples consisting of an HIV-positive father and HIV-negative mother participated in the study, and all medical treatment was funded by He Jiankui. The parent company of the Shenzhen hospital where the experiment was carried out said that signatures on an application to the hospital's medical ethics committee had been forged. Chinese Deputy Minister of Science and Technology Xu Nanping called the experiment unlawful. Jiankui indicated that he had consulted with ethics experts in recent years:

William Hurlbut, a senior researcher in neurobiology at the Stanford Medical School, said that he was one of the ethicists that He consulted with over the past two years. Hurlbut, who served on the U.S. president's council on bioethics, said that while he knew that He was "heading in this direction," he didn't know the full-scale of the project or that it involved implanted embryos. "I challenged him at every level, and I don't approve of what he did," said Hurlbut.

American scientist under investigation over ties to alleged genetic editing

Rice University has launched an investigation into one of its professors after reports surfaced that he is connected to alleged genetic editing in China that resulted in the birth of two babies with altered DNA. They announced the investigation Monday in the wake of reports that Dr. Michael Deem, a professor of biochemical and genetic engineering, was involved in a case in which genetic editing was performed on human embryos to alter a gene in a way to make them resistant to HIV. The university said that it had "no knowledge of this work" and that to its knowledge, the work was not performed in the U.S., where genetic editing of human embryos is illegal.

[...] Deem said he was in China when the participants agreed to genetic editing, and said they understood the risks, according to the Associated Press. Deem added that comparing the gene editing to a vaccine "might be a layman's way of describing it," according to the AP.

China orders probe into first 'gene-edited babies'

The National Health Commission said on Monday it was "highly concerned" and had ordered provincial health officials "to immediately investigate and clarify the matter". The government's medical ethics committee in Shenzhen said it was investigating the case, as was the Guangdong provincial health commission, according to Southern Metropolis Daily, a state media outlet.

China gene-editing scientist's project rejected for WHO database (original)

A Chinese branch of the World Health Organization has withdrawn an application to register He Jiankui's project in its clinical database. The move comes after China's government halted He's work, saying it would take a "zero tolerance attitude in dealing with dishonorable behavior" in research.

He has faced a global backlash after claiming to have produced the world's first gene-edited babies in a bid to make them HIV-resistant. The project drew international criticism for its lack of transparency, with health officials and other scientists concerned that it raises ethical questions that will taint other work in the field.

The application to enter the database of the Chinese Clinical Trial Registry was rejected because "the original applicants cannot provide the individual participants' data for reviewing," according to the registry's website.

[...] He's whereabouts are still unknown. Hong Kong newspaper Apple Daily cited unnamed sources earlier this month that the researcher was put on house arrest by his university, Southern University of Science and Technology in Shenzhen, but representatives of the university and He's lab both declined to comment.

takyon: Several news organizations reported on Dec. 3 that He Jiankui was missing.

Chinese scientist who allegedly created the first genetically engineered babies is being detained

The Chinese scientist who shocked the world with claims of creating the first genetically engineered babies is being detained in the Chinese city of Shenzhen, according to a report in The New York Times.

[...] The Southern University of Science and Technology, based in Shenzhen, has denied the reporting around Dr. He's whereabouts and fate, telling the Times, "Right now nobody's information is accurate, only the official channels are." Meanwhile, the official channels are staying silent.

Reporters found security personnel blocking access to the residence where Dr. He is reportedly staying and others denying access to the former offices Dr. He used to conduct his research. The scientist's name and biography remains on a board listing staff in the university’s biology department.

Russian biologist plans more CRISPR-edited babies

A Russian scientist says he is planning to produce gene-edited babies, an act that would make him only the second person known to have done this. It would also fly in the face of the scientific consensus that such experiments should be banned until an international ethical framework has agreed on the circumstances and safety measures that would justify them.

Molecular biologist Denis Rebrikov has told Nature he is considering implanting gene-edited embryos into women, possibly before the end of the year if he can get approval by then. Chinese scientist He Jiankui prompted an international outcry when he announced last November that he had made the world's first gene-edited babies — twin girls.

The experiment will target the same gene, called CCR5, that He did, but Rebrikov claims his technique will offer greater benefits, pose fewer risks and be more ethically justifiable and acceptable to the public. Rebrikov plans to disable the gene, which encodes a protein that allows HIV to enter cells, in embryos that will be implanted into HIV-positive mothers, reducing the risk of them passing on the virus to the baby in utero. By contrast, He modified the gene in embryos created from fathers with HIV, which many geneticists said provided little clinical benefit because the risk of a father passing on HIV to his children is minimal.

[...] "The technology is not ready," says Jennifer Doudna, a University of California Berkeley molecular biologist who pioneered the CRISPR-Cas9 genome-editing system that Rebrikov plans to use. "It is not surprising, but it is very disappointing and unsettling."

Alta Charo, a researcher in bioethics and law at the University of Wisconsin-Madison says Rebrikov's plans are not an ethical use of the technology. "It is irresponsible to proceed with this protocol at this time," adds Charo, who sits on a World Health Organization committee that is formulating ethical governance policies for human genome editing.

Third time's the charm? I guess they won't pick a genetic disease to target instead since preimplantation genetic diagnosis can already handle that. Others will have to resort to gene therapy after the child is born.

CRISPR scientist who made gene-edited babies sentenced to 3 years in prison:

The scientist who claimed to have created the first gene-edited human babies was fined around $430,000 and sentenced to three years in prison by a Chinese court on Monday, according to Chinese state media. He Jiankui was reportedly convicted of conducting an "illegal medical practice."

A court in Shenzhen reportedly found He, along with two colleagues, violated Chinese regulations and ethics by editing twin embryos' DNA. Authorities also found his team fabricated regulatory paperwork, according to state news agency Xinhua. He and his colleagues reportedly pleaded guilty to the charges.

He was condemned by the scientific community for using the gene-editing technology CRISPR to alter the gene CCR5, which HIV utilizes when infecting humans.
