Abstract

To determine the mode of inheritance and degree of penetrance of hypertrophic cardiomyopathy (HC) in Chinese, 132 family members of 28 probands with HC were assessed by M-mode and two-dimensional echocardiography. Of these 132, 103 cases were first-degree relatives of the probands. Twenty-seven (20.4%) family members, including 19 cases of first-degree relatives of the probands, had HC. Familial occurrence of HC was noted in 13 (46.4%) families. In 10 families, the affected relatives were identified in successive generations, and the mode of inheritance was most consistent with an autosomal dominant trait. The frequency with which HC was identified in relatives increased significantly with the number of subjects studied and a positive family history of sudden death. Subgroup analysis, using multivariate logistic regression analysis, revealed that increasing age was independently associated with a higher frequency of definite cases in first-degree relatives of the probands. In contrast, by multivariate analysis, there were no significant differences between frequency of definite cases in female and male relatives or in different familial relationships (parent, sibling, offspring) to the probands.
