Overview

Androgen insensitivity syndrome is due to hormone resistance which may be due to defective androgen receptor (AR) function by either abnormal androgen receptor (AR) binding, decreased receptor binding, or impaired androgen receptor (AR) binding. AIS is an X linked disorder. The development of androgen insensitivity syndrome is a result of genetic mutations of the androgen receptor (AR) gene located on the chromosome Xq11-12. Associated conditions include primary amenorrhea, infertility and dyspareunia.
