Abstract
Objective
To perform a meta-analysis to evaluate studies investigating the association
between ATG16L1 gene polymorphism and Crohn’s disease.
Methods
PubMed, Embase and Web of Science databases were searched for all studies
focusing on the association of ATG16L1 and Crohn’s disease.
Combined odds ratios with 95% confidence intervals were calculated for four
genetic models (allelic model: G allele versus A allele; additive model: GG
versus AA; dominant model: GA + GG versus AA; recessive model: GG versus
GA + AA) using either a random effects or fixed effects model.
Results
A total of 47 case–control studies involving 18 638 cases and 30 181 controls
were included in the final meta-analysis. There was a significant
association between ATG16L1 and Crohn’s disease for all
four genetic models. Significant associations were also shown in subgroup
analyses when stratified by study design (population- or
hospital-based).
Conclusion
In this meta-analysis, the ATG16L1 genotype was
significantly associated with the risk of developing Crohn’s disease.
