title: Autosomal dominant secundum atrial septal defect with various cardiac and noncardiac defects: a new midline disorder.
abstract: We report on a Lebanese family in which 12 persons had an atrial septal defect and various cardiac and noncardiac anomalies. Cardiac anomalies are left axis deviation of QRS, right bundle branch block, atrial fibrillation, Wolff-Parkinson-White syndrome, nodal atrioventricular rhythm, aortic stenosis, pulmonic valve stenosis, mitral stenosis (Lutembacher syndrome), and low implantation of the tricuspid valve (Ebstein disease). Noncardiac abnormalities consisted specially of the presence of hypertelorism, cleft lip, and pectus excavatum. This combination appears to constitute a hitherto undescribed autosomal dominant midline disorder of the heart and upper half of the body with almost full penetrance and variable expressivity. The mutation does not map to any known locus involved in atrial septal defect or conduction block.
