ABSTRACT
<p><b>OBJECTIVE</b>To screen the MYBPC3 gene mutations in Han Chinese patients with hypertrophic cardiomyopathy (HCM).</p><p><b>METHODS</b>Sixty-six patients with HCM were enrolled for the study. The exons in the functional regions of MYBPC3 were amplified with PCR and the products were sequenced.</p><p><b>RESULTS</b>Four novel mutations and four common polymorphisms were identified in this patient cohort. A Lys301fs mutation in exon10 was evidenced in a H30, and when he was 47 years old, he had the chest tightness, shortness of breath with septal hypertrophy of 18.7mm; a Asp463stop mutation in exon17 was detected in a H48, he was 24 years old 24-year-old when a medical examination showed ventricular septal hypertrophy of 15.4 mm; both Gly523Arg mutation in exon18 and Tyr847His mutation in exon26 were found in a H53 with onset age 36 years old, feeling chest tightness after excise and his ventricular septal hypertrophy was 27 mm that time. MYBPC3 mutations occurred in 4.5% patients in this cohort. These mutations were not found in 100 non-HCM control patients.</p><p><b>CONCLUSION</b>MYBPC3 mutation is presented in a small portion of Han Chinese patients with HCM.</p>
