Aspies For Freedom

I seem to recall reading somewhere that quite a few number of NT relatives of autistics had the same genetic markers for autism as the autistic themself, even though they weren't on the spectrum. Is that true or not? Wondering because of the prenatal testing thing.

I think it could be true.

Yep. Highly possible.

If that's the case, then wouldn't that be enough to pretty much entirely discredit pre natal testing?
