Does anyone know? To what extent does it run in families? I am considering, right now as a remote possibility, a pregnancy with my current partner. He himself is very well adjusted socially and his kids are all OK without dx; the oldest one has a bf and runs a start-up at 21, so no problem for sure. But his younger brother who is in his 30s has never had a gf, does not come to see his parents at all and does not attend family gatherings on holidays even though the parents live in the SF Bay area and he lives close by - in LA, does not call his parents and in general shuns interactions. The brother is very advanced academically. He has not sought mental health care but the combination of his stellar academic record with social ineptitude makes my partner think that the brother has Asperger's.

So I want to know to what extent it runs in families and what the chance is that the hypothetical baby would have Asperger's. I do not feel ready to deal with an ASD child. I think I have bipolar figured out and am prepared to deal with a child with bipolar if need be (which would be fairly likely because my mother was bipolar as well), but I am afraid that I would be unable to skillfully raise an Asperger's child. So this question is very important to me.
