Familial hypertrophic cardiomyopathy. Genetic characterization.

Genetic factors in familial hypertrophic cardiomyopathy: does molecular cardiology offer new perspectives?

Sporadic hypertrophic cardiomyopathy due to de novo myosin mutations.

Hypertrophic cardiomyopathy occurs as an autosomal dominant familial disorder or as a sporadic disease without familial involvement. While missense mutations in the beta cardiac myosin heavy chain (MHC) gene account for approximately half of all cases of familial hypertrophic cardiomyopathy, the molecular causes of sporadic hypertrophic cardiomyopathy are unknown. To determine whether beta card...

Progress in familial hypertrophic cardiomyopathy: molecular genetic analyses in the original family studied by Teare.

In this journal in 1958 Donald Teare reported the pathological findings in a series of eight unrelated young adults who died suddenly and who at necropsy had manifested gross asymmetrical hypertrophy of the heart.' In a footnote, he noted the recent sudden death of the brother of one of the original cases, thus identifying the familial nature of this condition. The subsequent report2 of two gen...

Mapping a gene for familial hypertrophic cardiomyopathy to chromosome 14q1.

To identify the chromosomal location of a gene responsible for familial hypertrophic cardiomyopathy, we used clinical and molecular genetic techniques to evaluate the members of a large kindred. Twenty surviving and 24 deceased family members had hypertrophic cardiomyopathy; 58 surviving members were unaffected. Genetic-linkage analyses were performed with polymorphic DNA loci dispersed through...

Apical Hypertrophic Cardiomyopathy in a Case with Chest Pain and Family History of Sudden Cardiac Death: A Case Report

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiovascular disease, which is caused by a multitude of mutations in genes encoding proteins of the cardiac sarcomere (1). Apical hypertrophic cardiomyopathy (AHCM) is an uncommon type of HCM. The sudden cardiac death is less likely to occur in the patients inflicted with AHCM (2). Herein, we presented the case of a 29-year-old man ...
