We report on 10 Japanese individuals from 3 families affected with Aar
skog syndrome. Pulmonary stenosis and ventricular septal defect with s
pontaneous closure were detected respectively, in 2 of them as an unco
mmon finding. A review documented 169 non-Japanese cases (2 with conge
nital heart defects), while of 30 Japanese individuals reported till n
ow, 4 (including ours) had cardiac anomalies. We propose that this com
bination is not coincidental and that in all cases of Aarskog syndrome
a cardiac evaluation is indicated. (C) 1994 Wiley-Liss, Inc.
