Autism (and its entire spectrum of disorders) is actually pretty common1 in 166 people have it. If you have one child with autism, the risk for the next child is only 2-6%. If autism were due to a single gene, we might expect numbers like 25% or 50%.
I have a son diagnosed with Aspergers, very intelligent and high functioning, there are no "answers" per se, he fits into the world in his own way and he is happy with that.
