Description : Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH) is characterized by utero-vaginal atresia
in an otherwise phenotypically normal female with a normal 46,XX karyotype. Anomalies
of the genital tract range from upper vaginal atresia to total mullerian agenesis
with urinary tract abnormalities. It has an incidence of approximately 1 in 5,000
newborn girls (Cheroki et al., 2006). The abnormality of sexual development in MRKH
syndrome is the same as that in the MURCS association (601076), in which cervicothoracic
somite anomalies, unilateral renal agenesis, and conductive deafness are also seen.
Mullerian aplasia and hyperandrogenism (158330) is caused by mutation in the WNT4
gene (603490). Familial cases of unilateral or bilateral renal agenesis in combination
with mullerian anomalies have also been reported (see urogenital adysplasia, 191830).;
