How many people have been officially diagnosed with ASD and have at least 1 parent who is either suspected to be Autistic or is confirmed as such

I've only really thought about this post-diagnosis but my father was absolutely on the spectrum. He was never diagnosed but looking back a lot of his traits/quirks would be explained by autism. Beyond that - I have no idea.

There's also a strong genetic component to it too. They say that is the dominating factor over environment but there are no official Autism genes that directly allow it to be inherited. Instead I think there are >= 60 odd that are involved with 20 that are the most connected with it but that still don't quality as the gold Autistic genes. I'd liken it to the mutants in the marvel comics. Some people are naturally born mutants from mutant parents, and others acquire it instead. Metaphorically speaking of course
