The two androgens responsible for all aspects of male sexual differentiation are testosterone and dihydrotestosterone. The action of both these steroids is mediated by a specific intracellular receptor, the androgen receptor, which is a member of the nuclear receptor superfamily. The androgen receptor gene has been cloned and is located on the X chromosome at Xq11-12. Mutations of this gene have been found in subjects with both complete and partial androgen insensitivity. In a study of 27 subjects with the androgen insensitivity syndrome, we have identified mutations in 14, using a rapid mutation screening assay. The same technique has also been used to determine carrier status in an affected family. We have also identified a mutation in two brothers who show perineal hypospadias as the only evidence of undervirilisation. Familial severe hypospadias should therefore be included as part of the phenotypic spectrum of partial androgen insensitivity. The study of naturally occurring mutations of the androgen receptor gene is providing further information on the function of the androgen receptor and its role in normal male sexual differentiation.
