Male transsexualism. Confirmation of a hypothesis?

Persistent confusion and the grouping together of similar disorders of differing origins confuse the question of genetic influences of male transsexualism. A 27-year-old adopted biological male transsexual was seen for psychiatric referral. At the time of the initial interview, events of her early development were unknown to her, and were elucidated by her adoptive mother. Her history seems to sever the genetic link between parent and child, while maintaining the psychoenvironmental continuity seen in patients who have been diagnosed as having transsexualism.
