Complete androgen insensitivity syndrome: A novel mutation in a Tunisian family

Introduction.-Complete androgen insensitivity is a rare syndrome. It is caused by a mutation in the androgen receptor gene. We describe a novel mutation in exon 1. Materials and methods.-We report the case of a 29 year-old girl with complete androgen insensitivity syndrome discovered during the exploration of a primary amenorrhoea. The family investigation revealed two other cases. Results.-The diagnosis was oriented by the clinical and the biological features and confirmed by the molecular study. A new mutation of the androgen receptor gene, as a deletion in exon 1 not described previously, was identified. Conclusion.-Through these cases, clinical, hormonal and histological particularities were analysed. (C) 2008 Elsevier Masson SAS.
