A targeted cardiomyopathy gene panel (Table 1) was performed, revealing 2 heterozygous disease-causing variants, MYH7 (NM_000257.3) c.2770G>A p.Glu924Lys and PKP2 (NM_004572.3) c.1295_1323dup p.Leu442Argfs∗5, associated with HCM and ARVC, respectively. Here, MYH7 is linked to Arrhythmogenic right ventricular dysplasia.
