Well, I can name a few just off the top of my head:
Various personality disorders, such as Antisocial Personality Disorder, Narcissistic PD, Asexual, Social phobias etc... I'm not saying these conditions are inevitable or even directly linked to high IQ, but I do know a couple of people who are very intelligent but otherwise lead secluded lives which indicate at least one of the mentioned disorders. The IQ is definitively a factor, very likely a contributing factor. Would need larger sample to be sure.
