• Genome-wide association studies found genetic variations with modulatory effects for intracranial aneurysm (IA) formations in European and Japanese populations. We aimed to identify the susceptibility of single nucleotide polymorphisms (SNPs) to IA in a Korean population consisting of 250 patients, and 294 controls using the Asian-specific Axiom Precision Medicine Research Array. Twenty-nine SNPs reached a genome-wide significance threshold (5 × 10 ). The rs371331393 SNP, with a stop-gain function of (11q24.3), showed the most significant association with the risk of IA (OR = 43.57, 95% CI: 21.84⁻86.95; = 9.3 × 10 ). Eight out of 29 SNPs- (rs75822236), (rs112859779), (rs79134766), (rs371331393), (rs138525217), (rs74115822), (rs75861150), and (rs116969723)-demonstrated sufficient statistical power greater than or equal to 0.8. Two previously reported SNPs, rs700651 ( , 2q33.1) and rs6841581 ( , 4q31.22), were validated in our GWAS (Genome-wide association study). In a subsequent analysis, three SNPs showed a significant difference in expressions: the rs6741819 ( , 2p25.1) was down-regulated in the adrenal gland tissue ( = 1.5 × 10 ), the rs1052270 ( . 9q22.33) was up-regulated in the testis tissue ( = 8.6 × 10 ), and rs6841581 ( , 4q31.22) was up-regulated in both the esophagus ( = 5.2 × 10 ) and skin tissues (1.2 × 10 ). Our GWAS showed novel candidate genes with Korean-specific variations in IA formations. Large population based studies are thus warranted.
