Müllerian duct anomalies-limb anomalies syndrome

Müllerian duct anomalies-limb anomalies syndrome (also known as Al-Awadi/Raas-Rothschild syndrome or limb/pelvis-hypoplasia/aplasia syndrome) is an extremely rare genetic disorder characterized by the combination of malformations of the Müllerian duct derivatives (uterus, fallopian tubes, and upper vagina) with limb abnormalities. The condition primarily affects the reproductive system and the skeletal/limb system. Key clinical features include absence or severe underdevelopment of the uterus and other Müllerian structures in affected females, along with limb defects that can range from split hand/foot malformations to severe limb reduction defects including absence of long bones (phocomelia or amelia). Pelvic abnormalities, including hypoplasia or aplasia of the pelvis, may also be present. Some cases have been reported with additional features such as renal anomalies and craniofacial findings. The syndrome has been described in a small number of families in the medical literature, and cases have been associated with mutations in the WNT7A gene or the LRP4 gene in some reports, though genetic heterogeneity exists. The condition follows an autosomal recessive inheritance pattern, meaning both parents must carry a copy of the altered gene for a child to be affected. Diagnosis is typically made at birth or prenatally based on the characteristic combination of limb and genital anomalies, often confirmed through imaging studies and genetic testing. There is currently no cure for this syndrome. Treatment is supportive and symptomatic, focusing on orthopedic management of limb defects (including prosthetics and surgical interventions as needed), management of reproductive anomalies, and addressing any associated renal or other organ involvement. A multidisciplinary team including orthopedic surgeons, gynecologists, geneticists, and rehabilitation specialists is typically involved in the care of affected individuals.
