Evidence of variations in genetic prevalence for loss-of-function PKP2 variants between individuals with European and African ancestry

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited condition associated with increased risk for ventricular arrhythmias and sudden cardiac death. Prior ARVC studies contained majority European-ancestry individuals; however, limited data have shown an increase in disease-associated variants in individuals of African ancestry. This study aimed to assess genotype/phenotype differences by ancestry across several cohorts.
