ABSTRACT
The present study was performed to identify the genetic abnormalities in a family with familial hypertrophic cardiomyopathy.Peripheral blood samples were collected from 22 members of a Chinese family with hypertrophic cardiomyopathy and 307 healthy controls. A total of 26 candidate pathogenic genes were analyzed in the proband using targeted capture sequencing. Identified mutations were analyzed using Sanger sequencing in all family members and healthy controls.A missense mutation (c.1172A>C, p. Asn391Thr) in exon 12 of MYH7 was identified in eight family members, among which six of them were hypertrophic cardiomyopathy carriers. Three carriers presented with cardiac dysfunction. Four members of this pedigree died suddenly, three of whom were diagnosed with hypertrophic cardiomyopathy.From the results of this study, we concluded that the Asn391Thr mutation of MYH7 is a malignant mutation for HCM and that mutation carriers should get effective treatment to prevent sudden death.
