Smith-Magenis syndrome (interstitial deletion of chromosome 17p) and congenital heart disease

Abstract

SummaryA syndrome with characteristic facial and skeletal features resulting from a specific deletion of material on the short arm of chromosome 17 was first described by Smith et al in 1982.1 The common findings are brachycephaly, hypoplasia of the middle face, and short broad hands associated with mental retardation. More than 50 cases have been reported, and about one third have congenital heart disease. We report here a patient with atrial and ventricular septal defects together with pulmonary valvar stenosis.
