| pubmed-article:16789403 | pubmed:abstractText | It has been estimated that more than 30% of patients with idiopathic dilated cardiomyopathy have a familial form of the disease. The most frequent pattern of inheritance is autosomal dominant and several genes or loci have been implicated, coding for sarcomeric or cytoskeleton proteins. Most of the genotype-phenotype correlations are still under study, but a particular mutation, K210del in the troponin T gene, has been identified in four different families with severe forms of DCM. The pathogenesis of this mutation has been inferred by functional studies but its transmission has not been demonstrated, perhaps due to the high mortality of the affected family members. The aim of this work was to investigate the prevalence of the K210del mutation in Portuguese and Mozambican families with dilated cardiomyopathy. | lld:pubmed |
