    Abstract:
    Androgen insensitivity syndrome (AIS) is a rare X-linked recessive condition in which patients with 46,XY karyotype have a complete (CAIS) or partial (PAIS) impairment of pre- and postnatal virilization due to mutations in the androgen receptor (AR). We present a concise revision of AIS and the AR and report the clinical, hormonal and molecular study of 33 subjects with AIS. The coding region of the AR was analyzed in 33 subjects with clinical and hormonal characteristics that suggested AIS. Eleven patients (9 families) had CAIS and 22 patients (12 families) had PAIS. Mutations in the AR were identified and the molecular diagnosis of AIS established in 100% of families with CAIS and 75% with PAIS. Nine mutations had been previously described (N705S, W741C, M742V, R752X, Y763C, R779W, M807V, R855C e R855H) and 7 mutations were first described in these cohort of patients (S119X, T602P, L768V, R840S, I898F, P904R e IVS3 - 60 G>A).
