In the first-ever study combing the entire human genome for genetic determinants of male sexual orientation, a University of Illinois at Chicago researcher has identified several areas that appear to influence whether a man is straight or gay.

UIC's Brian Mustanski, working with colleagues at the National Institutes of Health, found stretches of DNA that appeared to be linked to sexual orientation on three different chromosomes in the nucleus of cells of the human male.

"There is no one 'gay' gene," said Mustanski, a psychologist in the UIC department of psychiatry and lead author of the study. "Sexual orientation is a complex trait, so it's not surprising that we found several DNA regions involved in its expression."
