One possible explanation is that (typical) females will tend to have less severe symptoms, since they have a second X chromosomes that essentially provides a "backup" of many genes, I know that's true for fragile X syndrome which can cause autism.

Saying that one cause of autism exclusive to males is Klinefelter syndrome, which is XXY.

Would that not imply that the incident count be lower in women? If they are getting fewer diagnosis than men makes me think that they socially adept better to not qualify, which on the other hand does not diminish their possible suffering.

I would think it would be less severe.

Girls still have Fragile X, just the way it affects them is far less severe than boys, as in there's no obvious external effects from what I recall. It specifically affects math and spatial skills.

(But it's been a while since I read about it).
