Abstract
We describe five patients with Fryns syndrome. Four presented with diaphragmatic hernia and died in the neonatal period. One did not have diaphragmatic involvement and survived but is severely mentally retarded. All patients had “coarse” faces, microretrognathia, macrostomia, and distal digital hypoplasia. In addition to previously reported traits, our patients had clinical manifestations that have not previously been described, including omphalocele, broad claviles, Hirschsprung “disease,” and anal anomalies. The condition was detected antenatally in three of the cases. The patients include two sib pairs, further supporting autosomal recessive inheritance.
