title: Advances in molecular genetics of dilated cardiomyopathy. The Heart Muscle Disease Study Group.
abstract: In clinical surveys, familial dilated cardiomyopathy (FDC) has been demonstrated in 20% to 30% of patients. In these patients, the cause of the disease lies at the DNA level. Molecular genetic studies represent the tools for the understanding of the etiology of FDC and are currently producing relevant advances: 6 different loci have been mapped so far. The only known disease gene is the dystrophin gene causing X-linked dilated cardiomyopathy, but other cytoskeletal proteins, such as adhalin, could be involved. In familial right ventricular cardiomyopathy (or arrhythmogenic right ventricular dysplasia) characterized by isolated or prevalent right ventricular involvement, three further disease loci have been identified.
