Objective To confirm the clinical diagnosis of complete androgen insensitivity syndrome (CAIS) by molecular genetic analysis and to determine the prevalence of exon 1 mutations in the androgen receptor (AR) transactivation defects of a large series of CAIS patients. Design International retrospective study. Setting University Hospital of Montpellier, Department of Hormonology. Patient(s) 105 patients with normal female external genitalia, bilateral intra-abdominal or inguinal testis, normal breast development, absent or sparse pubic hair, normal or high endogenous testosterone production, hypoplastic or absent wolffian structures, and 46,XY karyotype. Intervention(s) Sequencing of the AR gene. Main Outcome Measure(s) Prevalence of AR exon 1 mutations. Result(s) Over a 10-year period (1997 to 2007), we identified 78 AR gene mutations in 105 patients with CAIS; 21 of them were located in exon 1, and 13 of these were new mutations. We report 13 new mutations in the AR gene. All but one were stop codons, and the last was a splicing abnormality. Conclusion(s) The finding that 27% of the mutations in our cohort were localized in exon 1 versus 15% in previous works justifies the sequencing of this exon in patients with CAIS.
