    The Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome affects at least 1 out of 4500 women and has for a long time been considered as a sporadic anomaly. Congenital absence of upper vagina and uterus is the prime feature of the disease which, in addition, is often found associated with unilateral renal agenesis or adysplasia as well as skeletal malformations (MURCS association). The phenotypic manifestations of MRKH overlap various other syndromes or associations and thus require accurate delineation. Since MRKH manifests itself in males, the term GRES syndrome (Genital, Renal, Ear, Skeletal) might be more appropriate when applied to both sexes. The MRKH syndrome, when described in familial aggregates, seems to be transmitted as an autosomal dominant trait with an incomplete degree of penetrance and variable expressivity. This suggests the involvement of either mutations in a major developmental gene or a limited chromosomal deletion. Until recently progress in understanding the genetics of MRKH syndrome has been slow, however, now HOX genes have been shown to play key roles in body patterning and organogenesis, and in particular during genital tract development. Expression and/or function defects of one or several HOX genes may account for this syndrome

    Item does not contain fulltextMayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is characterized by the congenital absence of uterus and upper part of the vagina as a result of Mullerian duct agenesis. The combination of MRKH syndrome with renal anomalies and cervicothoracic dysplasia is known as MURCS association (Mullerian aplasia, Renal anomalies, and Cervicothoracic Somite dysplasia). The etiology remains poorly understood. We delineate this disease by reporting on a 16-year-old patient showing the cardinal features of MURCS association accompanied by a persistent left superior vena cava and atrial septal defect, orofacial clefting, and mild reduction deformities of the left hand. Fluorescence in situ hybridization did not show major deletions or duplications of the DiGeorge/VCFS (velocardiofacial syndrome) region at chromosome 22q11.1 as well as the TBX5/TBX3 region at 12q24.1. In addition, sequencing of the TP63L (p63) gene, residing at 3q27, remained normal in the presented patient. Thus, we provide further evidence for the genetic heterogeneity of MURCS association
