Clinical summary

Help

Imported from GeneReviews

Androgen insensitivity syndrome (AIS) is typically characterized by evidence of feminization (i.e., undermasculinization) of the external genitalia at birth, abnormal secondary sexual development in puberty, and infertility in individuals with a 46,XY karyotype. AIS represents a spectrum of defects in androgen action and can be subdivided into three broad phenotypes: Complete androgen insensitivity syndrome (CAIS), with typical female external genitalia. Partial androgen insensitivity syndrome (PAIS) with predominantly female, predominantly male, or ambiguous external genitalia. Mild androgen insensitivity syndrome (MAIS) with typical male external genitalia.
