Trans gene theory; Health In association with the NHS.

A 'transsexual gene' has been discovered in women who would rather be one of the lads. The gene variant is linked to female-to-male transsexuality, and affects an enzyme which is involved in the processing of sex hormones. People with the variant have higher levels of male and female sex hormones, which may in turn influence early brain development.

Austrian scientists spotted the association after analysing DNA samples from 49 female-to-male and 102 male-to-female transsexuals. Among women, around 44% of FtM transsexuals carried the gene variant compared with 31% of non-transsexual women.

New Scientist magazine said: "This raises the possibility that the variant makes women more likely to feel that their bodies are the wrong sex"
