Cytokines and their receptors are involved in the development of intracerebral hemorrhage (ICH). Interleukin 23 receptor (IL23R) has been implicated in numerous inflammatory and immune diseases. In this study, we investigated whether single nucleotide polymorphisms (SNPs) of IL23R were associated with the susceptibility of ICH in Korean population. Two coding region SNPs (cSNPs) [rs1884444 (Gln3His), and rs7530511 (Leu310Pro)] were selected, and genotyped in 167 ICH patients and 377 control subjects using direct sequencing. Of two cSNPs, only rs7530511 showed a significant association with ICH in codominant model (C/T vs. C/C, P  = 0.017, odds ratio (OR) 4.15, 95 % confidential interval (CI) 1.27–13.58). Allele frequency analysis also revealed that rs7530511 was associated with ICH ( P  = 0.023, OR 3.68, 95 % CI 1.19–11.32). The frequency of the T allele was increased in the ICH patients, compared to the control subjects. These results suggest that IL23R may contribute to the development of ICH.
