Autism and genetics

If both parents are autistic, what are the chances of it having some form of autism versus it being non-autistic? Does this change at all with different parts of the spectrum? I know that autism isn’t always directly genetic, but I’m curious.

This maybe more of GD, but some people I know of some to think that high functioning autistics are the next step in evolution, and that we’re ‘better’ than neurotypicals(non-autistics). It sounded like bullshit, but I’m curious if there’s anything factual to back up such a opinion.

There is research into this being conducted at the moment. You might want to contact these organisations: Tufts New England Medical Center and Stanford University.

Here’s an interesting article on autism/aspergers, including the point that it does seem to run in families.

Thanks for the links.

I’m gonna’ call BS on:

My reason being that while some persons on the autistic spectrum do in fact evidence a high degree of performance in several fields, in general one cannot call a phenotype “more evolved” if it reduces your number of off-spring.
Autism, asperger’s and associated symptom sets don’t generally result in particularly gregarious people who have lots of life partners and lots of children.
If you can find evidence asserting the opposite of my last assertion, please post it.
I have Asperger’s, and I’ll be darned if it has made me more likely to reproduce… in fact, it has da**ed near gotten me killed a half dozen times.
