pregnancy and autism

Hi, New here but not new to autism. I have a son and two girls with autism. All to different degrees from HD to LD. My wife and I split up 10 years ago. However we still work very closely in bringing up our children. But, I have met some one else and we would like to have a baby. I am Very concerned. Neither my family, my ex's family or my existing partner have any members in their family with autism or on the spectrum. or at least so it seems. My question is. . .what is the chances of our baby being on the spectrum?? Thank you for your help

I would agree; this question is more appropriate for the genetics forum. I am personally not aware of definitive literature on the inheritability of autism, but hopefully a professional in genetics can answer your question.

Does your ex have autism in her family?
You also should post this question to the genetics forum. I believe that they have not indentified all the genes that might cause autism. They only have indentified one or two genes that explain about 20% of the cases. Either way, I am not a doctor but you need to tell the expert on this forum if your ex wife (mother of your autistic children) has herself or has family members with autism.  You also can use the genetics forum.
