We identified an unusual novel nonsense mutation in exon 3 of the androgen receptor (AR) gene in a patient with complete androgen insensitivity that was persistence of Wolffian derivatives. Sequence analysis revealed a substitution (C→T) at position 2211 and a deletion of G at position 2213 in exon 3 of the AR gene, resulting in the conversion of arginine(CGG) to a stop codon (TGA) of the AR. Western blotting demonstrated a truncated AR with around 70 kd was expressed. Histology of patient's testes showed that seminiferous tubules were totally filled with Sertoli cells without germ cells. Immunohistochemistry revealed positive AR localization in the nuclei of Sertoli cells and epithelia of efferent ductule and vas deferens. AR immunoexpression was stronger in the epithelia of efferent ductule and vas deferens than in Sertoli cells. The study extends the spectrum of exon 3 mutations in the AR gene.

D013734 Androgen-Insensitivity Syndrome A disorder of sexual development transmitted as an X-linked recessive trait. These patients have a karyotype of 46,XY with end-organ resistance to androgen due to mutations in the androgen receptor (RECEPTORS, ANDROGEN) gene. Severity of the defect in receptor quantity or quality correlates with their phenotypes. In these genetic males, the phenotypic spectrum ranges from those with normal female external genitalia, through those with genital ambiguity as in Reifenstein Syndrome, to that of a normal male with INFERTILITY.
