First genetically edited human babies reportedly born

In summary: I don't know, information??.In summary, the researcher claims he helped make the first genetically edited babies, which he says were twins whose DNA he altered with a powerful new tool. There is no independent confirmation of his claim, and it has not been published in a journal, where it would be vetted by other experts. The babies and pregnant women involved are unknown at this point.

HONG KONG (AP) — A Chinese researcher claims that he helped make the world’s first genetically edited babies — twin girls whose DNA he said he altered with a powerful new tool capable of rewriting the very blueprint of life.

[...]

The researcher, He Jiankui of Shenzhen, said he altered embryos for seven couples during fertility treatments, with one pregnancy resulting thus far. 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.

He said the parents involved declined to be identified or interviewed, and he would not say where they live or where the work was done.

There is no independent confirmation of He’s claim, and it has not been published in a journal, where it would be vetted by other experts. He revealed it Monday in Hong Kong to one of the organizers of an international conference on gene editing that is set to begin Tuesday, and earlier in exclusive interviews with The Associated Press.

As detailed in the AP news story, most scientists believe the work to be unethical as the safety of the CRISPR gene editing technique used has not yet been fully established.

No responses in 4 days; this at least deserves an emphatic "Wow!"
Nothing about this surprises me.

This results in a fertilized zygote with three parents genetically speaking: the mother's nuclear genome, the father's nuclear genome, and the mitochondrial genome derived from a third party.

Apparently, people from these origins, have been born and Walk Among Us!

There's so little to be gained by doing what the Chinese team did, I wonder if those embryos were planted in the womb of an HIV+ woman. That, fundamentally, makes sense beyond a "proof of concept" or benign genomic alteration.

On the contary, human experimentation is the highest form of demonstration available in bio-medicine.

Given 20 years followup or more of such a cohort without any huge side-effects, would probably highly accelerate the process from in vitro to in vivo studies, eventually even leading to similar cohorts and or even larger studies such as GWAS and/or RCT.

It goes without saying that for the time being, ethically the cons clearly outweigh the pros to create such a cohort, which is why a techniquesuch as CRISPR/Cas has to go through all the regular hoops before reaching the stage of clinical research; once such a cohort exists however, close followup is practically a necessity.

The Chinese government has looked into this and says:
deliberately sidestepped regulations, dodged oversight, and used fake ethical review documents in hopes of gaining "personal fame" for a worldwide first
He (proper noun, not pronoun) is losing his job at a university and losing his opportunities to do teaching and research.

Another update this time from the https://www.nytimes.com/2019/01/23/health/gene-editing-babies-https://www.physicsforums.com/insights/dont-fear-crispr-new-gene-editing-technologies-wont-lead-designer-babies/.html?emc=edit_th_190124&nl=todaysheadlines&nlid=388106970124.
Turns out the He had discussed his research with several other researchers (mostly in the US).
Most tried to dissuade him, several thought they had.
None seemed to have known how what further they could do about it, if they were so inclined.
The article also discusses issues about what to do going forward; research moratoriums, blocking publication, who/where to notify about potential upcoming problems, etc.
Its a good article with a fair amount of details.
 

1. What are genetically edited human babies?

Genetically edited human babies are babies whose genetic information has been intentionally altered through the use of advanced biotechnology, specifically gene editing techniques, to modify certain characteristics or traits.

2. How are these babies genetically edited?

The babies are genetically edited using a technique called CRISPR-Cas9, which allows scientists to precisely modify specific sections of DNA by cutting, removing, or replacing targeted genes.

3. Why were these babies genetically edited?

The parents of the babies reportedly wanted to protect them from inheriting a genetic disease called HIV, which is caused by a virus that attacks the immune system.

4. What are the potential risks and benefits of genetically edited human babies?

The risks include potential unintended consequences and ethical concerns surrounding the alteration of human DNA. The benefits may include the prevention of genetic diseases and the potential for improving human health and lifespan.

5. What are the ethical considerations surrounding the birth of genetically edited human babies?

There are many ethical considerations surrounding the birth of genetically edited human babies, including questions about safety, consent, equality, and potential unintended consequences. There is also a debate about whether or not this technology should be used for cosmetic or non-medical purposes.
