Mayer-Rokitansky-Kuster-Hauser syndrome
Spectrum of Mullerian duct anomalies characterized by congenital aplasia of the uterus and upper 2/3 of the vagina in otherwise phenotypically normal females. It can be classified as either MRKH syndrome type 1 (corresponding to isolated utero-vaginal aplasia) or MRKH syndrome type 2 (utero-vaginal aplasia associated with other malformations).
