Mullerian agenesis, also known as Mayer Rokitansky Kuster Hauser (MRKH) syndrome, is characterized by utero-vaginal atresia in an otherwise phenotypically normal female with a normal 46,XX karyotype. It has been reported that Mullerian aplasia and hyperandrogenism is caused by mutations in the WNT4 gene. WNT4, a secreted protein that suppresses male sexual differentiation, is thought to repress the biosynthesis of gonadal androgen in female mammals.
