The edited gene is for CCR5, which currently doesn’t have known function, but is the entry point for HIV. So editing for prophylaxis. This was probably done because if there aren’t a ton of loss of function beneficial traits, and probably with the main desire to be first. Except, if the reports are true, this is not just an experiment but a person (or people). I guess the main desire is to normalize editing. Brave new world I guess, whether we like it or not.

This is quite interesting. There is a certain very small percentage of the world's population that is immune to the HIV virus. These people's T-cells have the CD4 receptor, but not the CCR5 receptor. The HIV virus needs both these receptors to successfully affect the host's cells. The absence of the CCR5 receptor still allows the person's T cells to function normally, so if this works, it can pave the way to creating offspring who are immune to HIV

I guess time will tell if it leads to any adverse effects. I'm not a biologist which is probably why I'm more wary of this, but if there is some unforeseen circumstances then we'll find out I suppose.

> It's "unconscionable ... an experiment on human beings that is not morally or ethically defensible," said Dr. Kiran Musunuru, a University of Pennsylvania gene editing expert and editor of a genetics journal.

This is 100% correct.

(COI: Kiran was my postdoc while I was a student in the lab a decade ago.)

the edit was also confirmed and voluntarily implanted in-vitro in willing participants.

It's ethically black as far as I am concerned but it has already happened so we must see where this takes us. IVF born edited zygotes might have serious complications but ideally its a healthy human being. (for everyone's sake)

in vitro sex selection (mostly for male children) has been going on for a long time, seems the next logical step: https://www.google.com/search?&q=in+vitro+sex+selection+chin...

Gender selection, will have adverse effect without a doubt, nature has a healthy balance between the number of men and women in the world, and certain culture preferring boys / girls will lead to us having too much of one and not enough of the other. There is already evidence of this in China and India.
