        Association of Single Nucleotide Polymorphisms in Toll-like Receptor Genes With Asthma Risk: A Systematic Review and Meta-analysis

        Kalthoum Tizaoui,Wajih Kaabachi,Kamel Hamzaoui,Agnès Hamzaoui 대한천식알레르기학회 2015 Allergy, Asthma & Immunology Research Vol.7 No.2

        Purpose: Asthma is a complex disease, with contributions from multiple genes, various genetic backgrounds, and environmental factors. Many humanepidemiological studies have demonstrated that single nucleotide polymorphisms (SNPs) in Toll-like receptor (TLR) genes are inconsistently associatedwith asthma risk. Some have demonstrated differences concerning the study design and effect size, and conflicting results have been reported. A meta-analysis is necessary to determine the magnitude of this association. Methods: Following the Preferred Reporting Items for SystematicReviews and Meta-analyses guidelines, a systematic search and meta-analysis of the literature was conducted to estimate the associationof SNPs in TLR genes with asthma risk. We screened the medical literature based on the following keyword searches in MEDLINE and EMBASE databases:‘TLR’, ‘polymorphism’, ‘asthma’, and their combinations. Results: Meta-analysis of eight studies on TLR4 Asp299Gly showed a marginalassociation of TLR4 with asthma risk (odds ratio [OR]=0.814 [95% confidence interval [CI], 0.652-1.016; P=0.069]) in the recessive model. TLR4Thr399Ile was not associated with asthma risk under any genetic model. Meta-analysis of four studies on TLR2 Arg753Gln indicated that TLR2might be significantly associated with asthma in the dominant and codominant models (P=0.029, P=0.030, and P=0.009, respectively). TLR9 -1237was marginally associated with asthma risk (OR=0.408 [95% CI, 0.163-1.021; P=0.065]) in the codominant model. Analysis using the allele contrastmodel showed that the major TLR9 -1237 T allele tended to be a significant protective factor with OR=0.689 (95% CI, 0.471-1.007; P=0.055). Conclusions: The results showed that TLR4 Asp299Gly, TLR2 Arg753Gln, and TLR9-1237 might contribute significantly to asthma susceptibility. Futuregenetic association studies would consolidate these findings.
