Interesting development on autism

Surrounded as I am with autistic spectrum disorders (Hubby is Aspergers, nephew is severe autistic, godson is mild/moderate autistic), any developments in the field catches my attention. This study indicates that every case of autism has a highly individual genetic cause, making a universal genetic test hard, to say the least.

This actually jives with what I've observed - that autism is a catch all diagnosis for a bunch of disparate disorders with common symptoms. Why else would one kid respond to therapy but another doesn't, when both have similar symptoms?

Interesting thoughts, to say the least.
