Abstract

Objectives: We performed a systematic review and meta-analysis to estimate the polymorphism effects of IL18RAP and CCR3 on celiac disease susceptibility.

Methods: PubMed and Web of Science databases were searched (to June 2015) on IL18RAP rs917997 and CCR3 rs6441961 polymorphisms.

Results: The meta-analysis included 16 and 7 studies for rs917997 and rs6441961, respectively. The minor risk A allele at both rs917997 and rs6441961 carried risks (odds ratios) of 1.24 (95% CI 1.18-1.31) and 1.21 (95% CI 1.12-1.31), respectively. These alleles contributed to increase risks in all celiac disease patients by 5.04 and 6.35%. The estimated lambdas were 0.73 and 0.51, suggesting that an additive model would be the best choice for both gene effects.

Conclusions: This meta-analysis provides robust estimates that IL18RAP rs917997 and CCR3 rs6441961 are potential risk factors for celiac disease in European populations. Studies are needed to confirm these findings in different ethnicities.

Keywords: CCR3; IL18RAP; celiac disease; genetic association studies; meta-analysis.
