Autosomal recessive intestinal lymphangiectasia and lymphedema, with facial anomalies and mental retardation.

We report on two male and two female relatives with intestinal lymphangiectasia; severe lymphedema of limbs, genitalia, and face; facial anomalies; seizures; mild growth retardation; and moderate mental retardation. Main facial anomalies are a flat face, flat nasal bridge, hypertelorism, small mouth, tooth anomalies, and ear defects. Their parents are consanguineous. This disorder probably is an hitherto undescribed autosomal recessive syndrome.
