    Abstract

    The prevalence of Werdnig-Hoffmann disease was found to be 0.66 per 10,000 livebirths in Hungary from 1973 to 1980. However, the true prevalence is estimated to be 1 per 10,000 livebirths, which exceeds the level of a previously published English study. There was no higher fetal death rate in previous and subsequent pregnancies of index patients' mothers. The occurrence in sibs was 32%, probably because of greater ascertainment in families with more than one affected child.
