Background Large artery disease (LAD), cardioembolism (CE), and small vessel disease (SVD) are well-established causes of ischemic stroke. Although a founder variant of RNF213 has been regarded a genetic susceptibility for Moyamoya disease (MMD) and certain types of intracranial atherosclerotic stenosis (ICAS), correlations between RNF213 variants and ischemic stroke with SVD remain largely unknown. Objectives This study aimed to characterize the associations of four RNF213 polymorphisms (4448G>A, 4810G>A, 4863G>A, and 4950G>A) with ischemic stroke subtypes in Koreans. Methods Genetic data from 529 stroke patients were analyzed and compared to 424 age- and sex-matched controls. Genetic variants of RNF213, as obtained from the Human Gene Mutation Database, were analyzed in the study subjects using the polymerase chain reaction restriction fragment length polymorphism assay. We investigated four single-nucleotide polymorphisms of RNF213 to elucidate their association with ischemic stroke [LAD, (n = 192), SVD (n = 145) and CE (n = 51)]. Results The RNF213 4950G>A genotype was observed more frequently in cerebral stroke patients and was more strongly associated with SVD than LAD (P = 0.014). RNF213 4448/4950 in combination with G–A was higher in SVD patients. However, the RNF213 4863/4950 allele combination was associated with increased risk of SVD and LAD. These results confirmed that RNF213 4950GA+AA variants were more frequent in ischemic stroke, especially in SVD, and that RNF213 G–G–G–A and G–G–G–A (4448/4810/4863/4950) haplotype sequences play a role in LAD and CE as well as SVD. Conclusions Our data reported that the RNF213 4950G>A genotypes and several RNF213 (4448/4810/4863/4950) haplotypes were associated with ischemic stroke in Koreans.
