OBJECTIVES: The study investigated the potential role of eight candidate genes in the susceptibility to idiopathic dilated cardiomyopathy (IDC). BACKGROUND: Idiopathic dilated cardiomyopathy has a familial origin in 20% to 25% of cases, and several genetic loci have been identified in rare monogenic forms of the disease. These findings led to the hypothesis that genetic factors might also be involved in sporadic forms of the disease. In complex diseases that do not exhibit a clear pattern of familial aggregation, the candidate gene approach is a strategy widely used to identify susceptibility genes. All genes coding for proteins involved in biochemical or physiological abnormalities of cardiac function are potential candidates for IDC. METHODS: We studied 433 patients with IDC and 401 gender- and age-matched controls. Polymorphisms investigated were the I/D polymorphism of the angiotensin I-converting enzyme (ACE) gene, the T174M and M235T polymorphisms of the angiotensinogen (AGT) gene, the A-153G and A+39C polymorphisms of the angiotensin-II type 1 receptor (AGTR1) gene, the T-344C polymorphism of the aldosterone synthase (CYP11B2) gene, the G-308A polymorphism of the tumor necrosis factor-alpha (TNF) gene, the R25P polymorphism of the transforming growth factor beta1 (TGFB1) gene, the G+11/in23T polymorphism of the endothelial nitric oxide synthase (NOS3) gene and the C-1563T polymorphism of the brain natriuretic peptide (BNP) gene. RESULTS: None of the polymorphisms were significantly associated with the risk or the severity of the disease. CONCLUSIONS: We did not find evidence for an involvement of any of the 10 investigated polymorphisms in the susceptibility to IDC.
