No evidence for an association between the rs2824292 variant at chromosome 21q21 and ventricular fibrillation during acute myocardial infarction in a German population

Abstract

Background: In a recently published genome-wide association study (GWAS), three single nucleotide polymorphisms (SNPs) (rs2824292, rs1353342, rs12090554) were significantly associated with increased susceptibility for ventricular fibrillation (VF) during acute myocardial infarction (AMI). The association of rs2824292 could be confirmed in a second cohort. Both cohorts were from the Netherlands. We aimed to replicate this association in a German cohort of AMI patients with or without VF. Methods: We included a German cohort of 90 individuals with AMI and VF (cases) and 167 AMI individuals without VF and used Taqman assays for SNP typing. Results: None of the loci showed evidence for a statistically significant association with VF. The observed genotype frequencies of the three loci were in Hardy-Weinberg equilibrium, which essentially excludes genotyping errors. Conclusions: In contrast to the data from the Netherlands, we could not detect a significant association of the rs2824292 locus and risk of VF during AMI in our German cohort. Differences in recruitment and clinical phenotypes between the Dutch and German cohorts may underlie different genotype associations. © 2011 by Walter de Gruyter Berlin Boston.
