Only a systematic review was conducted for rs12119179, rs11209032, and rs12141431, owing to the lack of sufficient data.<b>Conclusion</b>: This meta-analysis indicated that rs17375018 (G/A) and rs924080 (T/C) were associated with BD susceptibility.
The results also suggested that both rs11209032 AA and rs17375018 GG of IL-23R are predisposing genotypes for BD and that the AGCG haplotype may provide protection against BD.
