Dilated cardiomyopathy (CMD) is characterized by cardiac dilatation and reduced systolic function. CMD is the most frequent form of cardiomyopathy and accounts for more than half of all cardiac transplantations performed in patients between 1 and 10 years of age. A heritable pattern is present in 20 to 30% of cases. Most familial CMD pedigrees show an autosomal dominant pattern of inheritance, usually presenting in the second or third decade of life (summary by Levitas et al., 2010).
