February 9, 2018 at 10:55 am #367 kath 6 Posts Yes, I am sure that I’ve inherited my autism (Asperger’s), because when I was diagnosed, it became evident that e.g. there probably is some older relatives on my mother’s side, who most likely would have been diagnosed with autism, if they had been born today. But I’m thinking that it can be more than one recessive gene involved. My mother have some autistic traits, but not close to being classed as autistic, and by the way, my sister isn’t autistic. Whereas I also happen to have inherited narcolepsy from my father, genetic lottery, you’re either lucky, or not.
