I would say that as an autism researcher whose focus is in finding autism subgroups that I doubt that any specific receptor differences will not apply to the whole spectrum, probably just to one or several subsets

So glad to hear research is being done in that area.

I'm a dad of two autistic boys who I think would be very different categories. I have friends whose child isn't really autistic, they have a much more rare and specific diagnosis but it's so rare it's hard to get supports so they got him diagnosed as autistic because that criteria is so broad almost anyone can qualify.

Thank you for your work!
