I could swear I'd read some papers somewhere about paternal age being significant in autism. Something about how men produce a lot of sperm during their lifetimes, and by their 40s you're getting more genetic glitches than before.
I haven't heard of this, but if age of the parent matters at all, it would probably be the mother. If I remember correctly, in women all of the gametes (eggs) are created when they are concieved, then sort of go into stasis until they are needed, at which point they finish meiosis and go wait to be fertilized. Becauae of the long delay before they are used, genetic degradation can occur, resulting in many genetic issues. Mothers over (I think) 40 have an extremely increased riak of a child with down syndrome because of this.
