Interleukin-23R rs7517847 TG Polymorphism Contributes to the Risk of Crohn’s Disease in Caucasians: A Meta-Analysis

الملخص EN

The association between Interleukin-23R gene polymorphism and Crohn’s disease (CD) in Caucasians is still controversial.

Thus, a meta-analysis was performed to evaluate the correlation between this gene variant and CD risk.

We retrieved the available data from EMBASE and PUBMED until May 1, 2014, and evaluated the effect of rs7517847 in Caucasians.

The significant associations were confirmed between rs7517847 and CD risk in dominant models (TT/TG versus GG: OR = 1.652, 95% CI 1.277, 2.137), allelic model (T allele versus G allele: OR = 1.327, 95% CI 1.198, 1.469), homozygote comparison (TT versus GG: OR = 1.890, 95% CI 1.465, 2.437), heterozygote comparison (TG versus GG: OR = 1.509, 95% CI 1.161, 1.960), and recessive model (TT versus TG/GG: OR = 1.409, 95% CI 1.279, 1.552).

In conclusion, this meta-analysis demonstrates that rs7517847 is associated with the risk of CD in Caucasians.

These findings show that IL-23R genes confer susceptibility to CD in the Caucasians.
