Androgen-Insensitivity Syndromes, Partial

Medical Condition:
Androgen-Insensitivity Syndromes, Partial

A familial form of PSEUDOHERMAPHRODITISM 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; AR) gene. Severity of the defect in AR quantity or quality correlates with their phenotypes. The phenotype spectrum varies from those with normal female external genitalia in ANDROGEN-INSENSITIVITY SYNDROME, through those with genital ambiguity in Reifenstein Syndrome, to that of a normal male with INFERTILITY.
