Abstract excerpt

OBJECTIVE: To assess the association between transsexualism and allele and genotype frequencies of the common cytochrome P450 (CYP) 17 -34 T>C single nucleotide polymorphism (SNP). DESIGN: Case-control study. SETTING: Academic research institution. PATIENT(S): 102 male-to-female (MtF) and 49 female-to-male (FtM) transsexuals, 756 male controls, and 915 female controls. INTERVENTION(S): Buccal swabs and multiplex...
