Zusammenfassung: Summary Family investigations have been carried out on 32 propositi with functional obstructive subvalvular aortic stenosis. In the families of 15 propositors members were further-more affected. According to our own observations as well as to the literature this heart disease shows an autosomal dominant mode of inheritance with a reduced penetrance and variable manifestations. Using the maximum-likelihood-method, the risk of the brothers or sisters to be affected is calculated as being between $$\hat p = 0.287 \pm 0.0215$$ (k=0, rmin=1) and $$\hat p = 0.320 \pm 0.0748$$ (k=1, rmin=1). The probability of parents in the “familial” observations to be affected is between 32.9±8.1 and 33.3±8.1. Only one half of the cases observed are “familial”, the others are “sporadic”. It is not impossible, that a part of the sporadic cases could be dominant mutants, because the mean age of the fathers at the birth is higher than expected. 1432-1203
