[TOMT] [book/movie] "Gene-ass"

It was the story of a guy with autism, or something, who became the subject of an experiment to increase his IQ... then he became a certifiable genius for a couple months before the experiments wore off, but he didn't like it, because it changed who he was and he couldn't relate to his friends anymore.

Also I remember him saying that he was a 'gene-ass' at one point, i think that was a memorable line...
