Neurocristopathy syndrome: review of four cases.

Aberrant embryologic development of the neural crest may clinically result in one of several patterns of malformation. Four examples of the neurocristopathy syndrome are described that collectively feature a very broad range of expression in these infants. Because of the many expressions, the syndrome may not be recognized. We believe that greater familiarity with the disorder will aid in the discovery of unsuspected anomalies and provide clues about predisposing etiologies.
