Clinical and genetic issues in familial dilated cardiomyopathy.

Idiopathic dilated cardiomyopathy (IDC) is characterized by left ventricular dilatation and systolic dysfunction after known causes have been excluded. Idiopathic dilated cardiomyopathy occurring in families, or familial dilated cardiomyopathy (FDC), may occur in 20% to 50% of IDC cases. Sixteen genes have been shown to cause autosomal dominant FDC, but collectively may account for only a fract...

Update 2011: clinical and genetic issues in familial dilated cardiomyopathy.

A great deal of progress has recently been made in the discovery and understanding of the genetics of familial dilated cardiomyopathy (FDC). A consensus has emerged that with a new diagnosis of idiopathic dilated cardiomyopathy (IDC), the clinical screening of first-degree family members will reveal FDC in at least 20% to 35% of those family members. Point mutations in 31 autosomal and 2 X-link...

Role of Genetic Factors in Dilated Cardiomyopathy

Role of Genetic Factors in Dilated Cardiomyopathy

Dilated cardiomyopathy (DCM) is a heart muscle disease characterized by cardiac chamber enlargement and impaired systolic (and almost always diastolic) function. It is usually associated with heart failure, arrhythmias and/or conduction system disease and thromboembolic disease but may also be asymptomatic. DCM is diagnosed in the presence of left ventricular enlargement and systolic dysfunctio...
