The action of testosterone and 5 alpha-dihydrotestosterone are essential to the development of the male phenotype. Patients with karyotype 46,XY, resistant to these hormones, exhibit a wide spectrum of phenotypes: from phenotypic female, through a range of incomplete masculinization, to under-virilized, infertile man. These disturbances are caused by mutations in the androgen receptor gene (AR). We studied a 46,XY fenotypic female with typical symptoms of Complete Androgen Insensitivity Syndrome (CAIS). Multiple temperature single-stranded conformation polymorphism (MSSCP) and sequence analysis of exon 6 of the AR gene in a patient revealed a C2718T transition causing R786X mutation in the loop between helices VII and VIII of the LBD of the androgen receptor. The R786X mutation has been described in a patient with CAIS only once and no such mutations have been described in Eastern Europe.
