I don't think anyone else in my family, of the ones i know, have AS, at least not in any kind of way that's serious at all... And by that i mean that i don't think any of them have enough, or severe enough, traits to warrant a diagnosis. But i definitely still see some mild autistic-y traits traits scattered here and there in some of my immediate family, enough to see how they could have come together to make me. My mom is very gossipy and NT-ish mostly, but she has some "stim"-like motor mannerisms at times that are kind of unusual for NTs, like rocking and moving her legs(but she has Restless Leg Syndrome). My grandfather is the same way, i often see him rubbing his fingers together repetitively, and he'll sometimes get really focused on one particular thing, but other than that seems very NT. My dad is probably the closest to being an aspie... And depending on how loosely you take the diagnostic criteria he could *possibly* fall somewhere in the "mild AS" area... His nonverbal communication probably isn't great, but he still makes eye contact at normal levels and has a fairly normal range of facial expression from what i can tell.. he doesn't have many friends outside of our family.. he goes on and on about what HE wants to talk about(lately, it's usually politics and how much he hates liberals. LOL) without acknowledging others' contributions to the conversation or attempts to change the subject.. He gets a little bit obsessive about things sometimes, likes to pace back and forth, concentrates too much on details sometimes, yeah. Actually, from what i just wrote he sounds very aspie, lol, but his level of functioning is actually normal-ish(aside from not having many friends, but it's not like he's trying to these days) and these things cause little to no impairment in his life from what i can tell. He does like to talk to people and will sometimes start talking to a stranger like he's known them forever and start going on about this or that, even i can often tell he's being kind of "odd" in his approach sometimes.. But it's still not bad enough for people to think he's really weird. From what he tells me of his childhood and teen years he was perhaps a little introverted, but still well within the range of normal interaction, doing normal teenage boy things. His aspie-ish traits never seemed to affect his job, either. So, yeah.. While i can relate to him in a lot of ways, he still seems to generally understand how to be part of a group of people and everything better than i do when he actually wants to. His obsessions also aren't nearly as prominent as mine tend to be, despite his tendency to go on and on and on talking about a certain thing for longer than i usually will. And even with his tendency to do that, as long as someone doesn't get him started on one of those topics he usually does know what to say and when to say something to keep a conversation going much better than i do. In fact, if you asked him if he had any difficulty in social interaction, i'm pretty sure he would say no, despite some of his behaviors following a very classic aspie type of pattern. So, subclinical AS traits, i suppose. Or maybe just obsessive... Or maybe it has something to do with the head injuries he got when he was run over by a car as a kid... Whatever. But he goes along with the rest of the world and understands it all too well for me to see him as an aspie. And there are plenty of AS-related issues i've had where he was completely non-undertstanding and unable to relate to me. Getting overloaded or going into a meltdown, for instance. I don't think there has ever been once instance of me getting overloaded or having a meltdown where he did anything except make things worse by yelling at me or getting angry. In any case, i'm inclined to beleive that most of my autistic traits probably come from his side of the family.
