We present the case of a young survivor of SCA, carrier of double heterozygosity for mutations in the SNC5A and MYBPC3 genes, illustrating the complexity of genotype-phenotype associations and the difficulties of decisions regarding therapeutic interventions in inherited cardiac diseases.engDeath, sudden cardiacCardiomyopathy, hypertrophic, familialAdolescentBrugada syndromejournal article10.5935/abc.20170016
