General Discussion

MURCS association is a very rare developmental disorder that affects only females. The acronym MURCS stands for (MU)llerian, (R)enal, (C)ervicothoracic (S)omite abnormalities. This rare disorder is characterized by the absence of the uterus, cervix, and upper part of the vagina (mullerian aplasia); kidney (renal) abnormalities, including absent (agenic) and/or improperly positioned (ectopic) kidneys; and/or malformations of the spinal column, ribs, and/or arms. Some affected females may exhibit additional physical abnormalities, such as malformations of the head and facial (craniofacial) area. In individuals with MURCS association, symptoms vary from case to case.

MURCS association appears to occur randomly, with no apparent cause (sporadic). Some researchers suggest that the malformations associated with this disorder may result from abnormal changes in cellular material (blastema) in portions of the embryo that later develop into the arms, certain bones (vertebrae) in the spinal column, the kidneys, and adjacent structures (e.g., fallopian tubes).
