Description: (OMIM) 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 ...
Clinical Description OMIM Dilated cardiomyopathy, a disorder characterized by cardiac dilation and reduced systolic function, represents an outcome of a heterogeneous group of inherited and acquired disorders. Olson and Keating (1996) noted that causes include myocarditis, coronary artery disease, systemic diseases, ...
Molecular genetics OMIM In 5 of 11 families with autosomal dominant dilated cardiomyopathy and conduction system defects, Fatkin et al. (1999) identified 5 heterozygous missense mutations in the LMNA gene (150330.0005-150330.0009). Each mutation caused heritable, progressive conduction system disease (sinus bradycardia, ...

Clinical Description GeneReviews LMNA-related dilated cardiomyopathy (DCM) is characterized by left ventricular enlargement and reduced systolic function frequently accompanied by significant conduction system disease. LMNA-related DCM usually presents in adulthood either with conduction system disease commonly accompanied by arrhythmias or with symptomatic DCM, including heart failure or embolus from a left ventricular mural thrombus. However, LMNA-related DCM may be discovered in an asymptomatic person during a medical evaluation conducted for another reason (e.g., a routine preoperative ECG) or clinical screening of at-risk relatives....
Genotype-Phenotype Correlations GeneReviews No generalizable genotype-phenotype correlations have been established for LMNA-related DCM. ...
Differential Diagnosis GeneReviews The differential diagnosis of LMNA-related dilated cardiomyopathy (DCM) relates to the general phenotype of DCM of unknown cause. Current evidence indicates that IDC (i.e., DCM of unknown cause) may be familial (and therefore possibly genetic) in 20%-50% of cases....
Management GeneReviews Following the diagnosis of LMNA-related dilated cardiomyopathy (DCM), if not previously completed, a three- to four-generation family history should be obtained, and the following evaluations performed:...
