I agree with OliveOilMom. It would kind of be like coming out as an introvert, in a way, though AS and introversion are obviously not the same. You would be opening yourself up to abuse for not a whole lot of upside. Now if you think your parents would react supportively, and you are close, that is another thing. Of course I suspect if that were the case you would not necessarily be asking. I am probably wording this all wrong, but if you are an adult and independent and not needed parental understanding of your traits for a real concrete reason, I would let it go.
(Disclaimer --I tried discussing this with my mom, when my son was diagnosed---and she was in denial about me having it, my dad having it, my brother having traits, etc.. It did not go well. Luckily she "forgot" all about it, so I stopped bringing it up.)
