More information: that “CORD7” variant is actually in an IQ GWAS, but showed ~0 effect. Note that I couldn’t rule out the PROM1 variant in the same way since it’s much rarer and not in the GWAS.
I’m not sure what to make of it. Regardless of whether the variant does much in humans, I’m surprised that they found it had a big effect on one of the things they decided to measure (in fruitflies, and it isn’t exactly the same variant, but still). I think it’s only very weak evidence of the IQ thing being real, but it’s still surprising to me, so there might be something to be learned here.
