Status

A rare genetic syndrome with limb reduction defects characterized by skeletal malformations comprising absent or hypoplastic pelvic bones (including sacral agenesis or hypoplasia), intercalary limb deficiencies (phocomelia potentially combined with polydactyly, oligodactyly or ectrodactyly), and skull defects (frequently a defect of the occipital bone with or without meningocele). Additional features may include thoracic dystrophy, dysmorphic facial features (dysplastic and large ears, and a high and narrow palate), and genital malformations (Mullerian aplasia, agenesis of the uterus and vagina, micropenis with cryptorchidism). Growth and mental development are not affected.
