Yes I was trying to speak for a general audience.  Let me try again:  now that the protein has been *identified* (although I read a bit more since last night and it seems this protein was discovered in 2009 at U of T....they just hadn't uncovered the autism connection until now).   Anyway, now that researchers know it exists, they can develop pharmacological interventions based on that knowledge, including what you propose and possibly a variety of other things.  The point is, it's a real breakthrough IMHO.
