IIRC a CCR5 deletion leads to HIV resistance, but the homozygous allele also leads to immune transcription disruptions. I believe there was a Chinese geneticist that deleted CCR5 from twin embryos and got “disappeared” for it, but it remains to be seen what the consequences of that change are (I don’t remember if those embryos were implanted).

I’m of the opinion that we should approach this topic with caution until we know exactly what’s going on and the consequences of said alleles. Hypothetically speaking, imagine being born and chosen by this IQ method only to realize some horrible consequence later like asthma susceptibility in a world with decreasing air quality.

I’d be extremely pissed lmao. I could still find happiness even if I was less intelligent.

There’s another discussion about genetic homogenization that I don’t care to go into atm too.
