General Discussion

Seckel syndrome is an extremely rare inherited disorder characterized by growth delays prior to birth (intrauterine growth retardation) resulting in low birth weight. Growth delays continue after birth (postnatal), resulting in short stature (dwarfism). Other symptoms and physical features associated with Seckel syndrome include an abnormally small head (microcephaly); varying degrees of mental retardation; and/or unusual characteristic facial features including "beak-like" protrusion of the nose. Other facial features may include abnormally large eyes, a narrow face, malformed ears, and/or an unusually small jaw (micrognathia). In addition, some affected infants may exhibit permanent fixation of the fifth fingers in a bent position (clinodactyly), malformation (dysplasia) of the hips, dislocation of a bone in the forearm (radial dislocation), and/or other physical abnormalities.
