A gay gene? How about 54 of them?

Are gay and transgendered people born that way? A new study from the University of California, Los Angeles, supports the argument that sexual identity--and perhaps sexual orientation--may be "hardwired." In a study of mice, researchers identified 54 genes that functioned differently in male and female brains before the appearance of sex hormones.

The study's lead author, Eric Vilain, MD, said his finding "paves the way to find out which genetic factors cause gender identity issues." While the study has not identified a "gay gene," he said, it may aid in determining sexual identity's genetic origins, particularly in future studies. The study may also aid physicians in identifying the sex of infants born with ambiguous genitalia.
