Dilated cardiomyopathy is inherited in nearly 50% of cases. More than 90 genes have been associated with this disease, which is one of the main causes of heart transplant and has been associated with an increased risk of sudden cardiac death. Risk stratification in these patients continues to be challenging. The identification of the specific etiology of the disease is very useful for the early detection of mutation carriers. Genetic study often provides prognostic information and can determine the therapeutic approach. Wide phenotypic variability is observed depending on the mutated gene, the type of mutation, and the presence of additional genetic and environmental factors.
