Check out this URL from Slashdot regarding nerd genes that may be "Shadow Syndromes", i.e. mental disorders where the genetic mutations may cause milder symptoms or incomplete penetrance.
There is also a book: Shadow Syndromes, by Harvard psychiatrist John Ratey (co-authored with Catherine Johnson). Unfortunately Amazon.com is *CLOSED* right now (can you believe it...) so I can't give the URL.
I don't fit the whole collection they describe, but some of traits strike pretty close to home. Something they don't seem to mention is the possibility of offseting variants of other genes. This plot is going to get very thick before we find out who all the culprits and accessories are.
This is great, it means I'm "disadvantaged", I bet I can sue someone so I get to park in the handicapped parking spaces...
Give us about 4 years and I'll be pricking peoples fingers at Extro9 (informed consentually of course) so we can find them there "libertarian" genes...
