Nineteen pathogenic and 15 likely pathogenic variants resided in the primary electrical disorder genes, mainly RYR2, KCNQ1, KCNH2, and SCN5A. In the cardiomyopathy genes, we found 1 pathogenic variant in PLN and 5 likely pathogenic variants in TTN (n = 3), PKP2 (n = 1), and MYH7 (n = 1). The gene discussed is MYH7; the disease is cardiomyopathy.
