RBM20 and Schnyder corneal dystrophy: Figure 2 illustrates the frequency of diagnoses across genetic variants. Notably, diagnoses of sudden cardiac death (SCD), hypertrophic cardiomyopathy (HCM), and dilated cardiomyopathy (DCM) are strongly associated with variants in genes DSG2, SCN5A, PKP2, and RBM20. Figure 3 effectively illustrates the distribution of gene variants and co-occurrence patterns in the dataset.
