Harvard's George Church told Stat News that he has been in contact with He's team and has seen the experimental data.
Who could argue with such good intentions?
As the old proverb says, "The road to hell is paved with good intentions".
The researcher, He Jiankui of Shenzhen, said he altered embryos for seven couples during fertility treatments, with one pregnancy resulting thus far.
Given the secrecy involved, it is hard to verify Jiankui's claim.
His work has not yet been independently confirmed or reviewed by other scientists, but if proven true, it crosses into a new frontier of medicine and ethics. The mainline, old school version of eugenics assumed that superior traits were found in particular races, ethnicities, and particularly in the United Kingdom, social classes.
Knocking out CCR5 will likely render a person more susceptible to West Nile Virus, he said. This turned out to be hard. Canada has one of the most stringent laws, making it a crime - with punishment up to a $500,000 fine and 10 years in prison - to do any gene editing on germ cells, even if they will not actually be used to create a new life.
"Using these technologies prematurely can really adversely impact the entire scientific field", Caulfield went on. He has claimed that the resulting genomes were assessed at the embryonic stage, during pregnancy, and after birth to confirm that the intended gene alone was changed. It would be a significant step, and it's raised widespread ethical concerns among researchers. The debate was implicitly set up like a slippery slope.
Shenzhen Harmonicare Medical Holdings Limited, reported by media as being involved in He's project, sought to distance itself by stating the hospital never participated in any operations relating to the gene-edited babies and no related delivery had taken place. However, the slope was slippery. He said there appeared to be no harm caused to other genes.
"People are not quite clear about the long-term function of every gene yet". Once the DNA is cut out, naturally occurring fix mechanisms will glue the remaining gene strands together.
In the statement published on weibo.com, they said any attempt to change human embryos with genetic editing and allow the birth of such babies entails a high degree of risk due to inaccuracies in existing editing technologies. The main thrust of human study is addressing disease in "somatic" cells, those that can not be inherited.
Another barrier to the road to hell that turned out to be permeable was the wall between blocking disease and enhancing an individual.
A visual representation of CRISPR-Cas9 gene editing. He's goal was to introduce a rare, natural genetic variation that makes it more hard for HIV to infect its favorite target, white blood cells. He doesn't have a genetics or human health background at all. "We are not tinkering with plants and animals, as considerable as that might be, but with human beings". Immediately after the 2016 experiment, the scientists destroyed the embryos, saying more research will be required before modified embryos can be implanted in a mother's womb.
Many scientists have stated that Dr. Moreover, is deafness a disease? "These are all kinds of. rumors at this point. but in terms of scientific and medical rationale, I don't think there is one".
A recent report by the National Academy of Sciences concluded that the distinction between disease and enhancement is hopelessly muddled. "Society will decide what to do next" with the technology's ethical ramifications.
"I am. deeply concerned about the lack of transparency surrounding this trial", Zhang says in a statement published by MIT Technology Review. Organizers of the conference told reporters at a pre-event briefing they were awaiting further details.
