Abstract
Purpose: Accumulating evidence has shown that allergic diseases are caused by a complex interaction of genetic and environmental factors, some single nucleotide polymorphisms (SNPs) existing in high-affinity IgE receptor β chain (FcεRIβ) are potential risk factors for allergic diseases. However, the results have been inconsistent and inconclusive due to the limited statistical power in individual study. Thus, we conducted a meta-analysis to systematically evaluate the association between FcεRIβ SNPs and allergic diseases risk. Methods: Eligible studies were collected from PubMed, Embase, Web of Science, CNKI, and WanFang databases. Pooled odd ratios (ORs) and corresponding 95% confidence intervals (95%CIs) were calculated to assess the strength of the relationships between five polymorphisms (E237G, -109 C/T, RsaI_in2, RsaI_ex7 and I181L) and the risk of allergic diseases by using five genetic models. In addition, the stability of our analysis was evaluated by publication bias, sensitivity and heterogeneity analysis. Results: Overall, a total of 29 case-control studies were included in this meta-analysis. We found that E237G (B vs. A: OR = 1.28, 95%CI = 1.06-1.53, P < 0.001, I2 = 63.1%) and -109 C/T (BB vs. AA+AB: OR = 1.58, 95%CI = 1.26-1.98, P < 0.001, I2 = 66.4%) were risk factors for allergic diseases. Conclusion : Our meta-analysis suggests that polymorphisms in FcεRIβ, may be associated with the development of allergic diseases.
