A female monozygotic twin pair discordant for transsexualism. Some theoretical implications

Br J Psychiatry. 1992 Dec:161:852-4. doi: 10.1192/bjp.161.6.852.

Abstract

A 13-year-old girl was referred because of sexual identity problems. There was no mental illness or neurological abnormalities. As her twin sister had no sexual identity problems, it appears that transsexualism is not transmitted by a simple genetic mechanism.
