Abstract

A recent genome wide associated study in European descent population identified the association of Atrial fibrillation (AF) risk with a single nucleotide polymorphism (SNP) in SCN10A. The aim of this study was to evaluate whether SCN10A polymorphisms are associated with AF risk in the Chinese Han population. A total of 2,300 individuals of Chinese Han origin were recruited and three potentially functional SNPs were genotyped. Logistic regression models were utilized to calculate odds ratios (ORs) at a 95% confidence intervals (CIs). Logistic regression analysis in an additive genetic model revealed that one SNP in SCN10A (rs6771157) was associated with an increased risk of AF (adjusted OR = 1.20, 95% CI: 1.06-1.36, P = 0.003). Stratification analysis of several main AF risk factors indicated that the risk associations with rs6771157 were not statistically different among different subgroups. In summary, our study suggests the possible involvement of the SCN10A variant in AF development in Chinese Han populations. Further biological function analyses are required to confirm our finding.
