i was never diagnosed, but rather suspected. It was later learned that i was dissociating to escape the stress of everyday life into a bubble world filled with legos, tv, computer games, and over-eating. In comorbid, it developed into social anxiety, an intense phobia of rejection and abandonment as I feel rather alienated from social society. I was diagnosed BP II last year after about 6 months of observations and self reported episodes of mania, and depression.

But I have read a lot into it once my parents told me they suspected me autistic, and I have watched a lot of old home movies of me at a young age (like 4 or 5.), and I showed some autistic behaviors. Upon reading into AS, I have identified a lot into the social interaction aspects of AS, but little into the behavior or cognitive aspects of AS as an adult. Maybe AS is in remission; or I grew out of it, and into the world of BP, and Social Anxiety/Phobias.

But in any case, a lot of mental illnesses have been thought of as genetic, as well as other cases of developing them. BP is one of them, and I have been told my grand father was "very moody" on my father's side; it's possible it skipped a generation as my father reported instances of episodic depression, but no mania.

As for commonality of comorbid mental illness connected to AS, i'm not entirely sure to be honest. I have not met many other to have similar backgrounds in real life.
