Hirschsprung disease, postaxial polydactyly, and atrial septal defect

We report on an infant girl with Hirschsprung disease, postaxial polydactyly, and atrial septal defect who was born to a consanguineous Iraqi couple. A similar condition of aganglionic megacolon, postaxial polydactyly, and ventricular septal defect with a presumed autosomal recessive (AR) inheritance was reported by Laurence in two sibs [Laurence et al.; J Med Genet 12: 334-338, 1975].
