Abstract
Myocardial fibrosis is a common finding in victims of sudden cardiac death (SCD). Whole exome sequencing was performed in 127 victims of SCD with primary myocardial fibrosis as the only pathological finding. These cases are derived from the Fingesture study which has collected data from autopsy-verified SCD victims in Northern Finland. A computational approach was used to identify protein interactions in cardiomyocytes. Associations of the identified variants with cardiac disease endpoints were investigated in the Finnish national genetic study (FinnGen) dataset. We identified 21 missense and one nonsense variant. Four variants were estimated to affect protein function, significantly associated with SCD/primary myocardial fibrosis (Fingesture) and associated with cardiac diseases in Finnish population (FinnGen). These variants locate in cartilage acidic protein 1 (CRATC1), calpain 1 (CAPN1), unc-45 myosin chaperone A (UNC45A) and unc-45 myosin chaperone B (UNC45B). The variants identified contribute to function of extracellular matrix and cardiomyocytes.
