Outline of Final Research Achievements

We could register 77 cases of hypertrophic cardiomyopathy (HCM). Whole exome sequencing (WES) was performed on seven relatives from a large HCM family with a clear HCM phenotype (five clinically affected and two unaffected) in our registry study. WES detected 60020 rare variants in the large HCM family. After genotype-phenotype matching, 13 putative variants remained. Using combined annotation dependent depletion (CADD) score and high heart expression (HHE) gene data, the number of candidates was reduced to one, a variant in the myosin essential light chain, p.Arg94His.
