ABSTRACT
<p><b>OBJECTIVE</b>To explore the disease-causing gene mutation in Chinese families with hypertrophic cardiomyopathy (HCM) and to analyze the correlation between the genotype and phenotype.</p><p><b>METHODS</b>Samples of peripheral blood were collected from three Chinese families with HCM (at least two HCM patients existed/family). The exons in the functional regions of the beta myosin heavy chain gene (MYH7) were amplified with PCR and the products were sequenced.</p><p><b>RESULTS</b>A Val606Met missen mutation was identified in the exon 16 of MYH7 gene in a Chinese family and this mutation was identified in all HCM patients (n = 4) and there was also a 15-years-old young mutation carrier who was not HCM patient now (penetrance of 80%). This mutation was not identified in other healthy family members in this family, in other 2 Chinese familiar HCM families and in 120 non-HCM control patients.</p><p><b>CONCLUSION</b>The Val606Met missen mutation is closely associated with familiar HCM in a Chinese family which is associated with clinical phenotype with a penetrance of 80%.</p>
