Association of Interleukin-23 receptor gene polymorphisms with susceptibility to Crohn's disease: A meta-analysis.

ABSTRACT: Studies investigating the association between Interleukin-23 receptor (IL-23R) gene polymorphisms and Crohn's disease (CD) report conflicting results. Thus, a meta-analysis was carried out to assess the association between the IL-23R polymorphisms and CD. A systematic literature search was conducted to identify all relevant studies. Pooled odds ratio (ORs) with 95% confidence interval (CIs) was used to estimate the strength of association. Finally, a total of 60 case-control studies in 56 articles, involving 22,820 CD patients and 27,401 healthy controls, were included in the meta-analysis. Overall, a significant association was found between all CD and the rs7517847 polymorphism (OR?=?0.699, 95% CI?=?0.659?~?0.741, P?

Association of variants of the interleukin-23 receptor gene with susceptibility to pediatric Crohn's disease.

Project description:Recently an association was shown between the single nucleotide polymorphism (SNP), rs11209026, within the interleukin-23 receptor (IL23R) locus and Crohn's disease (CD) as a consequence of a genome-wide association study of this disease in adults. We examined the effects of this and other previously reported SNPs at this locus with respect to CD in children.By using data from our ongoing genome-wide association study in our cohort of 142 pediatric CD patients and 281 matched controls, we investigated the association of the previously reported SNPs at the IL23R locus with the childhood form of this disease.By using the Fisher exact test, the minor allele frequency of rs11209026 in the patients was 1.75%, whereas it was 6.61% in the controls, yielding a protective odds ratio (OR) of 0.25 (95% confidence interval, 0.10-0.65; 1-sided P = 9.2 x 10(-4)). Furthermore, of all the SNPs previously reported, rs11209026 was associated the most strongly. A subsequent family based association test (which is more resistant to population stratification) with 65 sets of trios derived from our initial patient cohort yielded significant association with rs11209026 in a transmission disequilibrium test (1-sided P = .0017). In contrast, no association was detected to the caspase-recruitment domain 15 gene for the inflammatory bowel disease phenotype.The OR of the IL23R variant in our pediatric study is highly comparable with that reported previously in a non-Jewish adult inflammatory bowel disease case-control cohort (OR, 0.26). As such, variants in the IL23R gene confer a similar magnitude of risk of CD to children as for their adult counterparts.

The association between genetic polymorphisms of the interleukin-23 receptor gene and susceptibility to uveitis: a meta-analysis.

Project description:Uveitis is an eye inflammatory disease, which is sometimes associated with underlying systemic disease. Interleukin-23 plays an important role in autoimmune disease. The aim of this meta-analysis was to evaluate the association between the interleukin-23 receptor (IL-23R) and susceptibility to uveitis.Published literature from PUBMED and EMBASE were retrieved. Seven studies were included in this meta-analysis, covering a total of 1309 cases of uveitis and 2400 controls. Meta-analyses were conducted on the associations between uveitisand rs7517847, rs17375018, and rs11209032 polymorphisms in the IL-23R gene.There were no significant associations between IL-23R polymorphisms and uveitis with regard to the following alleles: for G allele vs. T allele of rs7517847, OR 1.01, 95% CI 0.92-1.12, P = 0.83; for A allele vs. G allele of rs17375018, OR 0.68, 95% CI 0.47-0.99, P = 0.05; rs11209032 OR 1.12, 95% CI 0.84-1.51, P = 0.43. In contrast, there were significant associations between the AA + AG gene versus GG gene of rs17375018 and the AA gene versus AG + GG gene of rs11209032 polymorphism with uveitis (OR 0.59, 95% CI 0.35-0.99, P = 0.04; OR 1.32, 95% CI 1.10-1.59, P = 0.003).This meta-analysis suggests that each allele of IL-23R, including rs7519847, rs17375018 and rs11209032 was negatively associated with uveitis. However, homozygote models, including the rs17375018 GG genotype and rs11209032 AA genotype, were significantly associated with uveitis.

Functional polymorphisms in interleukin-23 receptor and susceptibility to coronary artery disease.

Project description:As a key element in the T-helper 17 (Th17) cell-mediated inflammatory process, interleukin-23 receptor (IL-23R) may play a crucial role in the pathogenesis of atherosclerosis. Single nucleotide polymorphisms (SNPs) in IL-23R have been studied in several diseases. However, its association with coronary artery disease (CAD) remains unclear. This study examined whether genetic polymorphisms in IL-23R were associated with susceptibility to CAD. Two IL-23R SNPs, rs1884444 and rs6682925, were genotyped in 462 CAD patients and 486 healthy controls. Data showed that percentages of rs6682925TC and CC genotypes were significantly higher in patients than in controls (odds ratio [OR]=1.23, 95% confidence interval [CI]: 1.04-1.79, p=0.022; OR=2.35, 95% CI: 1.52-3.43, p<0.001, respectively). Frequency of the rs1884444 polymorphism did not reveal any significant differences between patients and healthy donors. Further analyses demonstrated a significantly increased number of rs6682925CC genotype in patients with hypertension. Moreover, we investigated the effect of IL-23R polymorphisms on gene expression by assessing mRNA level of IL-23R in peripheral blood mononucleated cells (PBMCs). Results showed that subjects carrying rs6682925TC and CC genotypes had significantly increased mRNA level of IL-23R in PBMCs than those with TT genotype. These data suggest that IL-23R rs6682925T/C polymorphism may act as a risk factor of CAD.

Interleukin 23 in Crohn's disease.

Project description:: Crohn's disease (CD) is a lifelong inflammatory condition with underlying environmental and genetic components. CD affects multiple parts of the gastrointestinal tract, and it has a growing incidence in Western societies. IL-23 receptor variants have been identified as susceptibility or resistance factors for CD in genome-wide association studies. Accordingly, IL-23 is required for the development of experimental inflammatory bowel disease in many murine models. IL-23 receptor is expressed by both innate and adaptive immune cells, which include Th17, natural killer T, ?? T cells, and ROR?t innate lymphoid cells all of which are capable of secreting IL-17A, IL-17F, IL-22, and interferon-? upon IL-23 stimulation. During the past decade, pathogenic and protective roles have been described for these cytokines in the inflammatory bowel disease pathogenesis. More recently, innate lymphoid cells have been implicated in disease development. In this review, we have summarized and discussed these findings with an emphasis not only on the contribution of Th17 but also on innate lymphoid cells to disease etiology.

Vitamin D receptor gene polymorphism: association with Crohn's disease susceptibility.

Project description:BACKGROUND: The vitamin D receptor (VDR) gene represents a strong positional candidate susceptibility gene for inflammatory bowel disease (IBD). The VDR gene maps to a region on chromosome 12 that has been shown to be linked to IBD by genome screening techniques. It is the cellular receptor for 1,25(OH)(2) vitamin D(3) (calcitriol) which has a wide range of different regulatory effects on the immune system. IBD is characterised by activation of the mucosal immune system. AIM: To determine if polymorphisms in the VDR gene are associated with susceptibility to IBD SUBJECTS: European Caucasoids: 158 patients with ulcerative colitis, 245 with Crohn's disease, and 164 cadaveric renal allograft donor controls. METHOD: Single nucleotide polymorphisms (TaqI, ApaI, and FokI) in VDR were typed in patients with Crohn's disease, ulcerative colitis, and controls by polymerase chain reaction with sequence specific primers. RESULTS: There were significantly more homozygotes for the TaqI polymorphism at codon 352 of exon 8 (genotype "tt") among patients with Crohn's disease (frequency 0.22) than patients with ulcerative colitis (0.12) or controls (0.12) (odds ratio 1.99; 95% confidence interval 1.14-3.47; p=0.017). CONCLUSION: This study provides preliminary evidence for a genetic association between Crohn's disease susceptibility and a gene that lies within one of the candidate regions determined by linkage analysis.

Association between Interleukin-10 Gene Polymorphisms and Behcet's Disease Susceptibility: Evidence from a Meta-Analysis.

Project description:Epidemiological studies have demonstrated that interleukin-10 (IL-10) polymorphisms may be associated with the development of Behcet's disease (BD). However, the published results were inconsistent. Therefore, this meta-analysis was conducted to derive a more precise relationship between IL-10 polymorphisms and BD susceptibility. Online databases (PubMed, Embase, Science Citation Index (SCI), CNKI, and WanFang) were searched to identify eligible studies. Odds ratio (OR) and a 95% confidence interval (CI) were applied to assess the relationship strength between IL-10 -1082A>G (rs1800896), -819T>C (rs1800871), and -592A>C (rs1800872) polymorphisms and BD susceptibility. Publication bias, sensitivity, and cumulative analyses were conducted to measure the robustness of our findings. Finally, fifteen articles (36 independent case-control studies) involving 5,971 patients and 8,913 controls were included. Overall, significant associations between -819T>C polymorphisms and BD risk were observed in the total population (C vs. T: OR = 0.72, 95%CI = 0.67-0.77, P < 0.01, I 2 = 36.6%; TC vs. TT: OR = 0.73, 95%CI = 0.66-0.80, P < 0.01, I 2 = 23.0%; CC vs. TT: OR = 0.52, 95%CI = 0.39-0.70, P < 0.01, I 2 = 53.7%; TC+CC vs. TT: OR = 0.67, 95%CI = 0.61-0.71, P < 0.01, I 2 = 22.1%; and CC vs. TT+TC: OR = 0.66, 95%CI = 0.53-0.82, P < 0.01, I 2 = 57.8%). Moreover, the IL-10 -592 A>C polymorphism and the ACC haplotype exhibited a significant, protective effect against BD susceptibility. In summary, our meta-analysis suggested that IL-10 gene polymorphisms may play a salient role for BD development.

Association of interleukin-33 gene polymorphisms with susceptibility to late onset Alzheimer's disease: a meta-analysis.

Project description:The association between interleukin-33 (IL-33) gene polymorphisms and late onset Alzheimer's disease (LOAD) remains controversial in previous studies. Thus, a meta-analysis was conducted to assess the association between the IL-33 polymorphisms (rs11792633 and rs7044343) and LOAD susceptibility. Crude odds ratio (OR) and 95% confidence interval (CI) were used to investigate the relationship strength. Sensitivity analysis was performed, and publication bias was estimated by the Begg's and Egger's tests. Overall, six independent studies involving 2,589 patients and 8,414 control samples met our inclusion criteria and were included in this meta-analysis. The results showed that IL-33 rs11792633 polymorphism had statistically significant correlation with a decreased risk of LOAD in heterozygous comparison model (OR =0.64, 95% CI =0.48-0.83), homozygote comparison model (OR =0.83, 95% CI =0.74-0.93), dominant model (OR =0.78, 95% CI =0.67-0.91), recessive model (OR =0.70, 95% CI =0.59-0.84), and allelic model (OR =0.79, 95% CI =0.69-0.91), which were also validated by stratified subgroup analysis. Additionally, there was an apparent association between the IL-33 rs7044343 variant and LOAD risk under four genetic models for overall population (heterozygous comparison model: OR =0.75, 95% CI =0.63-0.89; dominant model: OR =0.83, 95% CI =0.70-0.98; recessive model: OR =0.80, 95% CI =0.68-0.94; allelic model: OR =0.86, 95% CI =0.79-0.94) as well as Caucasian subgroup. In summary, our meta-analysis implicated that IL-33 gene polymorphisms rs11792633 and rs7044343 were significantly associated with the susceptibility of LOAD.

Association of rs11209032 and rs1004819 Polymorphisms in Interleukin-23 Receptor Gene With Ankylosing Spondylitis.

Project description:Objectives:This study aims to investigate the distribution of human leukocyte antigen B27 (HLA-B27) alleles (+/-) and interleukin-23 receptor (IL-23R) gene rs11209032 and rs1004819 polymorphisms among ankylosing spondylitis (AS) patients in a Turkish cohort. Patients and methods:The study sample comprised 106 AS patients (89 males, 18 females; mean age 38.9±10 years; range 19 to 65 years) and 82 healthy controls (70 males, 12 females; mean age 32.15±7.07 years; range 19 to 51 years). Distribution of HLA-B27 alleles (+)/(-) in AS patients were observed by reverse hybridization technique. Genotyping of IL-23R rs11209032 and rs1004819 polymorphisms of AS patients and healthy controls were performed by real time polymerase chain reaction. Results:Of the AS patients, 69 (65.1%) were HLA-B27 positive. Distribution of rs11209032 genotype frequencies in AS group were 31.1% for GG, 50.9% for GA, and 17.9% for AA; while in control group, it was 34.1% for GG, 53.7% for GA, and 12.2% for AA. Distribution of rs1004819 genotype frequencies in AS group were 30.2% for CC, 52.8% for CT, and 17.0% for TT; while in control group, it was 42.7% for CC, 46.3% for CT, and 11.0% for TT. There was no significant difference between AS patients and controls in terms of genotype frequencies of IL-23R gene rs11209032 and rs1004819 polymorphisms. Conclusion:No association was found between AS and IL23R rs11209032 and rs1004819 polymorphisms in this Turkish AS cohort.

Association of interleukin-12 gene polymorphisms with cancer susceptibility: a meta-analysis.

Project description:OBJECTIVE:To evaluate the association between interleukin-12 (IL-12) gene polymorphism and cervical cancer susceptibility. METHODS:We comprehensively retrieved the relevant English and Chinese database to collect case-control studies on the association between the IL-12 gene polymorphism and cervical cancer susceptibility. Data were extracted independently by two researchers respectively, the summary data were analyzed using Revman 5.2 software, the association was described using odds ratios (OR) and 95% confidence intervals (95% CI). RESULTS:According to inclusion and exclusion criteria, 5 case-control studies involving 2552 cervical cancer patients and 2232 healthy controls were included. The meta-analysis results showed that 3'UTR+1188 (rs3212227) polymorphism in IL-12 gene was not associated with cervical cancer risk (C vs. A: OR=1.09, 95% CI: 0.88~1.35, P=0.45; AA+AC vs. CC: OR=0.88, 95% CI: 0.67~1.15, P=0.34; AA vs. AC+CC: OR=0.89. 95% CI: 0.56-1.42, P=0.62; CC vs. AA: OR=1.30. 95% CI: 0.79-2.12, P=0.30). CONCLUSION:The available evidence suggested that rs3212227 polymorphism in IL-12 gene may not be the risk factor to cervical cancer.

Association of interleukin 23 receptor gene with sarcoidosis.

Project description:Interleukin 23 receptor (IL23R) gene has been reported as a genetic factor strongly associated with inflammatory bowel disease, psoriasis, and ankylosing spondylitis. We investigated the association between IL23R gene single nucleotide polymorphisms (SNPs) and susceptibility to sarcoidosis, including the clinical manifestation of uveitis. Ninety-one sarcoidosis subjects (58 with and 33 without uveitis) and 104 healthy controls were genotyped for eleven IL23R SNPs. DNA was amplified using specific PCR primers and genotyped by denaturing HPLC and/or direct DNA sequencing. Case-control frequency comparisons were analyzed using Chi square test. Three IL23R SNPs, rs7517847 (intron 6), rs11465804 (intron 8), and rs11209026 (exon 9, c.1142G>A, p.Arg381Gln) were associated with sarcoidosis in our population (p<0.05): rs7517847 showed increased frequencies in sarcoidosis compared to controls, but rs11465804 and rs11209026 were decreased. Two of these SNPs were associated with the uveitis subgroup compared to controls: rs11465804 (0.9% vs. 7.2%, OR=0.11, P=0.013) and rs11209026 (1.8% vs. 7.3%, OR=0.23, P=0.038). This finding indicates the association of IL23R polymorphism with sarcoidosis, especially with sarcoid uveitis. IL23R may be a common susceptibility gene shared by several autoimmune disorders including inflammatory bowel disease, psoriasis, and ankylosing spondylitis and sarcoid uveitis.
