Mayer-Rokitansky-Kuster-Hauser Syndrome is a congenital disorder of the female reproductive tract due to impaired Müllerian duct development. There are three known categorical presentations: isolated, atypical, and MURCS association. Several developmentally significant factors including inappropriate AMH/AMHR interaction, and mutations in the WNT gene family and HOXA7-13 cluster have been studied. There has also been investigation into an autosomal dominant pattern of inheritance in families with multiple cases of the syndrome. Due to the presence of multiple subsets of patients with similar genetic abnormalities, it seems unlikely that a single etiology will be discovered.
