O Negative.
But I always read/understood autitistics (regardless of level of functioning) have a statistically significant propensity to Rh negative blood (like mine). Were you aware of this? I don't know why..I had never heard of the type A. I think it's the Rh factor that is significant, if any. Interesting though!
Most everyone is my family is O negative and there is a high genetic component to autism in my family.
