title: Parental genetic contribution to mode of presentation in Pompe disease.
abstract: Echocardiograms were performed on parents of five infants with Pompe disease (glycogen storage disease, type II). Three of the infants had presented with congestive cardiomyopathy and two with dynamic muscular subaortic stenosis. No heart murmurs were audible in any of the parents of the five infants. The parents of the three infants without left ventricular outflow tract obstruction had normal echocardiographic results, whereas one parent of each of the infants with left ventricular outflow obstruction had asymmetric septal hypertrophy. The association between left ventricular outflow obstruction and parental asymmetric septal hypertrophy suggests that both septal hypertrophy and glycogen storage disease were inherited by these two infants.
