I don't think so. He doesn't have most of the other features of P-W except the ones that involve speech and intellectual delay. He never had hypotonia, he does not have the facial characteristics, short stature (in fact this is the first year he was below the 50th percentile in height, and in the past he has been as high as the 80th percentile), and so on. Also, because he is autistic we had him genetically tested. I'm not sure but there are enough genes involved in P-W that I would think it would have shown up.

In any event, none of the doctors, geneticists, neurologists, and so on have ever suggested P-W.
