Foramen of Morgagni hernia in identical twins: is this an inheritable defect?

Abstract

Twins with Down's syndrome, foramen of Morgagni hernias, and similar cardiac anomalies are described. While diaphragmatic hernias are not uncommon, the occurrence of this congenital defect in twins with very similar congenital anomalies raises the possibility that diaphragmatic hernias may result from an inheritable defect.
