I'm so glad that someone finally said it! My guess is that the fact that teens can get it just made it easy fodder for the Nogitsune to use against Stiles... Given that it is an autosomal dominant gene mutation, it is, indeed, possible that he actually did inherit it from Claudia with the odds ration actually being 50/50.

That said, the Nogitsune would know that Stiles knows this (he strikes me as the type of kid who would do a ton of research on something like that, given the prologned amount of time he had to watch his mother suffer from it) and is using that information against him.
