BACKGROUND: Case-control studies have reported multiple genetic loci to be associated with sporadic brain arteriovenous malformations (AVMs) but most of these have not been replicated in independent populations. The aim of this study was to find additional evidence for these reported associations and perform a meta-analysis including all previously published results. METHODS: We included 167 Dutch patients and 1038 Dutch controls. Case genotyping was performed by KASPar assays. Controls had been previously genotyped with a genome wide single nucleotide polymorphisms (SNP) array. Differences in genotype frequencies between cases and controls were estimated by chi(2) testing in Plink V.1.07. Meta-analysis was performed in RevMan V.5.3. RESULTS: In our case-control study we found no significant association with brain AVM (BAVM) for previously discovered SNPs near ANGPTL4, IL-1beta, GPR124, VEGFA and MMP-3. The meta-analysis revealed a statistically significant association with BAVMs for the polymorphism rs11672433 near ANGPTL4 (OR 1.39; 95% CI 1.10 to 1.75, p value 0.005). CONCLUSIONS: The results of this study support a role for the previously identified SNP near ANGPTL4 in the pathogenesis of AVMs. Previously found associations with SNPs near IL-1beta, GPR124, VEGFA and MMP-3 genes could not be substantiated in our replication cohort or in the meta-analysis.
