P218: Inflammatory and arrhythmogenic cardiac phenotype associated with the DES c.832C>T (p.R278W) variant
Abstract
Pathogenic variants in DES, encoding the intermediate filament protein desmin, are linked to a spectrum of cardiomyopathies, including dilated (DCM) and arrhythmogenic right ventricular cardiomyopathy (ARVC). The DES c.832C>T (p.R278W) variant has been reported in DCM and hypertrophic cardiomyopathy (HCM) cohorts, though its ACMG/AMP pathogenicity classification remains disputed among commercial genetic laboratories (ClinVar Variation ID: 201703). We describe five individuals carrying this variant, their associated cardiac phenotypes, and complementary cellular studies assessing the biological effect of this variant on DES structure.
