Abstract
Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by T cells imbalance. Indeed, a correlation between levels of Th17 cells and disease activity has been reported. Our work aimed to study the functional association of subpopulations of Th cells and SLE with (lupus nephritis, LN) or without (lupus erythematosus, LE) renal involvement in Tunisian patients through the detection of intracellular cytokines and surface marker expression. The IL23R and RORC mRNA expression levels were evaluated. The level of Th17 and Th1 cells was higher in LE and LN patients compared to healthy controls (HC) (p = 0.007 and p = 0.018, respectively), while Th1/17 cells were increased only in LN patients compared to HC (p = 0.011). However, no significant difference was described in the mRNA expression levels of RORC and IL-23R between SLE and HC. Our findings suggest that the Th1/Th17 differentiation mechanisms are altered in SLE and that this imbalance should have an important influence on the development and severity of the disease.

Abstract
INTRODUCTION AND OBJECTIVES Considering the possible roles of interleukin-23 receptor (IL-23R) gene in the pathogenesis of juvenile systemic lupus erythematosus (JSLE), the objective of this study was to elucidate whether polymorphisms of the IL23R are associated with susceptibility to JSLE in an Iranian population. MATERIALS AND METHODS A case-control study on 62 patients with JSLE and 78 healthy controls was performed to investigate the associations of four single nucleotide polymorphisms (SNPs) in IL-23R gene, namely, rs7517847, rs10489629, rs11209026, and rs1343151, with susceptibility to JSLE, using real-time polymerase chain reaction Taqman genotyping technique. RESULTS Analysis of allele and genotype frequency of four selected SNPs revealed statistically significant positive association between homozygous variant of rs7517847 (TT) (P, 0.02) and T allele at the same position (P, 0.01) with JSLE vulnerability. There was no significant association between other evaluated SNPs and JSLE susceptibility. CONCLUSION These findings suggest that particular IL-23R gene variants could affect individual susceptibility to JSLE.

Abstract
Background Common variants of multiple genes played a crucial role in osteonecrosis of the femoral head (ONFH) onset which was proved by many previous reports. We hypothesized that polymorphisms in NOS3, ABCB1 and IL23R were related to individual differences in alcohol sensitivity and the development of alcohol-induced ONFH. Methods In this case-control study, we evaluated 8 SNPs in three genes in the Chinese Han population including 355 male cases and 355 healthy male controls. These SNPs were genotyped by Sequenom MassARRAY RS1000. To identify their relationship with alcohol-induced ONFH susceptibility using χ2 test and genetic model analysis. Results We found an association with alcohol-induced ONFH susceptibility for 4 SNPs (rs743506, rs3918184, rs13233308 and rs6693831) in three genes after adjusted by age. The genotype “G/A” of rs743506 in NOS3 gene acts as a risk factor in genotype (P = 0.003), dominant (P = 0.048), recessive (P = 0.005) and additive model(P = 0.006); The genotype “T/C” of rs3918184 in NOS3 gene acts as a risk factor in genotype (P = 0.012) and recessive model (P = 0.009); The genotype “T/C” of rs13233308 in ABCB1 gene acts as a risk factor in genotype (P = 0.038) and additive model(P = 0.041); The genotype “T/C” of rs6693831 in IL23R gene acts as a protective factor in genotype model (P = 0.046). Conclusions This study provides evidence for three alcohol-induced ONFH susceptibility genes (NOS3, ABCB1 and IL23R) in Chinese males and polymorphisms of them may be associated with alcohol-induced ONFH risk.

Abstract
Ankylosing spondylitis (AS) is a chronic inflammatory autoimmune disease, characterized by typically an axial arthritis. AS is the prototype of a group of disorders called spondyloarthropathies, which is believed to have common clinical manifestations and genetic predisposition. To date, the exact etiology of AS remains unclear. Over the past few years, however, the role of genetic susceptibility and epigenetic modifications caused through environmental factors have been extensively surveyed with respect to the pathogenesis of AS, resulted in important advances. This review article focuses on the recent advances in the field of AS research, including HLA and non-HLA susceptibility genes identified in genome-wide association studies (GWAS), and aberrant epigenetic modifications of gene loci associated with AS. HLA genes most significantly linked with AS susceptibility include HLA-B27 and its subtypes. Numerous non-HLA genes such as those in ubiquitination, aminopeptidases and MHC class I presentation molecules like ERAP-1 were also reported. Moreover, epigenetic modifications occurred in AS has been summarized. Taken together, the findings presented in this review attempt to explain the circumstance by which both genetic variations and epigenetic modifications are involved in triggering and development of AS. Nonetheless, several unanswered dark sides continue to clog our exhaustive understanding of AS. Future researches in the field of epigenetics should be carried out to extend our vision of AS etiopathogenesis.

Abstract
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.

Abstract
Expansion of myeloid-derived suppressor cells (MDSCs) has been documented in some murine models and patients with autoimmune diseases, but the exact role of MDSCs in this process remains largely unknown. The current study investigates this question in patients with systemic lupus erythematosus (SLE). Patients with active SLE showed a significant increase in HLA-DR(-)CD11b(+)CD33(+)MDSCs, including both CD14(+)CD66b(-)monocytic and CD14(-)CD66b(+)granulocytic MDSCs, in the peripheral blood compared to healthy controls (HCs). The frequency of MDSCs was positively correlated with the levels of serum arginase-1 (Arg-1) activity, T helper 17 (TH17) responses, and disease severity in SLE patients. Consistently, in comparison with MDSCs from HCs, MDSCs from SLE patients exhibited significantly elevated Arg-1 production and increased potential to promote TH17 differentiation in vitro in an Arg-1-dependent manner. Moreover, in a humanized SLE model, MDSCs were essential for the induction of TH17 responses and the associated renal injuries, and the effect of MDSCs was Arg-1-dependent. Our data provide direct evidence demonstrating a pathogenic role for MDSCs in human SLE. This study also provides a molecular mechanism of the pathogenesis of SLE by demonstrating an Arg-1-dependent effect of MDSCs in the development of TH17 cell-associated autoimmunity, and suggests that targeting MDSCs or Arg-1 may offer potential therapeutic strategies for the treatment of SLE and other TH17 cell-mediated autoimmune diseases.

Abstract
The association between Interleukin-23R gene polymorphism and Crohn's disease (CD) in Caucasians is still controversial. Thus, a meta-analysis was performed to evaluate the correlation between this gene variant and CD risk. We retrieved the available data from EMBASE and PUBMED until May 1, 2014, and evaluated the effect of rs7517847 in Caucasians. The significant associations were confirmed between rs7517847 and CD risk in dominant models (TT/TG versus GG: OR = 1.652, 95% CI 1.277, 2.137), allelic model (T allele versus G allele: OR = 1.327, 95% CI 1.198, 1.469), homozygote comparison (TT versus GG: OR = 1.890, 95% CI 1.465, 2.437), heterozygote comparison (TG versus GG: OR = 1.509, 95% CI 1.161, 1.960), and recessive model (TT versus TG/GG: OR = 1.409, 95% CI 1.279, 1.552). In conclusion, this meta-analysis demonstrates that rs7517847 is associated with the risk of CD in Caucasians. These findings show that IL-23R genes confer susceptibility to CD in the Caucasians.

Abstract
Polymorphisms of the interleukin-23 receptor (IL23R) gene have been found to play an important role in the development of several autoimmune diseases. We examined five susceptible (rs10889677, rs1004819, rs2201841, rs11805303, rs11209032), one protective (rs7517847) and two neutral variants (rs7530511, rs1884444) of the IL23R gene in pooled DNA of healthy Roma (Gipsy) and Hungarian population samples. Our aim was to determine the genetic variability of the major haplotype tagging polymorphisms, and the haplotype profile of IL23R between the two groups. We analyzed 273 healthy Roma and 253 Hungarian DNA samples using PCR/RFLP assay. Comparing the five susceptible conferring alleles, there were significant increase (p<0.05), while in the protective alleles, there were decrease in the allele frequencies in Roma population (p<0.05). One of the neutral alleles showed increase, the another one did not differ between the two groups. The haplotype analysis of the SNPs revealed fundamentally different association types of SNPs in the two groups; moreover, the frequencies of the various haplotypes also exhibited strong differences, as of ht4 and ht5 haplotypes were significantly higher, whereas the frequencies of ht2 and ht3 haplotypes were significantly lower in the Roma population than in Hungarians (p<0.05). The data presented here show profound differences in the IL23R genetic profiles in the Roma population, that likely has also clinical implications in respect their possible role in the development of certain immunological diseases.

Lack of association between IL-23R gene polymorphisms and systemic lupus erythematosus in a Chinese population. Inflamm Res 2013; 62:791-5. [PMID: 23754344 DOI: 10.1007/s00011-013-0636-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2013] [Accepted: 05/13/2013] [Indexed: 11/25/2022] Open
Abstract
OBJECTIVE The aim to this study was to investigate the association between the single-nucleotide polymorphisms (SNPs) of interleukin (IL)-23 receptor gene and systemic lupus erythematosus (SLE) in a Chinese population. METHODS A case-control study was performed to investigate the associations of SNPs in IL-23R gene (rs10889677 and rs1884444) with susceptibility to SLE in 521 Chinese SLE patients and 527 normal controls. The chi-square test and unconditional Logistic regression were used to analysis by SPSS 10.1 software. RESULTS No significant differences were detected for the distribution of allele and genotype frequencies of these two SNPs between patients and controls as well as SLE patients with nephritis (LN) and those without nephritis. CONCLUSION The findings suggest that the polymorphisms of IL-23R gene might not contribute to the susceptibility of SLE in the Chinese population.

Abstract
OBJECTIVE Polymorphisms of the interleukin-23 receptor (IL23R) gene have been found to play a role in the development of several autoimmune diseases. Our aim was to examine the possible effect of not only simple individual variants, but of haplotypes composed of them. SUBJECTS We analysed 263 patients with psoriasis, 199 patients with Crohn's disease (CD), 282 patients with ulcerative colitis (UC), and 253 controls for rs1884444, rs11805303, rs7517847, rs2201841, rs10889677 and rs11209032 variants. METHODS The genotypes were determined by using PCR/RFLP assay. Logistic regression analysis was used to compare the genotype distribution of the polymorphisms and haplotypes between the examined autoimmune diseases and healthy controls. RESULTS Rs1884444 was found to confer risk for UC and psoriasis, rs10889677 for CD and psoriasis, while rs2201841 and rs7517847 had effect only in CD. Using these SNPs we could study the susceptibility haplotype profiles in these diseases with special attention to UC. Eight different haplotypes could be differentiated. We found that the SNPs exert their susceptibility character in specific haplotype blocks, and the frequency of one haplotype differed significantly in UC compared with both other diseases and also with healthy controls. This haplotype conferred risk for UC, even while it had a somewhat lower frequency in the other diseases than in controls. CONCLUSIONS The data presented here serve as evidence for the need of haplotype analysis instead of just single standing SNP analysis when susceptibility is interpreted.

Abstract
Haplotype tagging SNPs of interleukin-23 receptor gene rs1004819, rs7517847, rs7530511, rs2201841, rs1343151 and rs10889677 were determined in 396 patients with rheumatoid arthritis, 190 patients with Crohn's disease, 206 patients with ankylosing spondylitis and 182 controls. Using regression analysis models the rs1004819, rs2201841, and rs10889677 SNPs were found to confer risk for Crohn's disease and ankylosing spondylitis, while rs1343151 had a protective effect in both of these diseases, and the rs2201841 and rs10889677 SNPs showed susceptibility nature for rheumatoid arthritis. Using these SNPs we could study the susceptibility haplotype profiles in these diseases with special attention to the rheumatoid arthritis, first in the literature. Seven different haplotypes could be differentiated. We found that the SNPs exert their susceptibility character in specific haplotype blocks: thus, for rheumatoid arthritis the rs1343151 SNP was risk factor only in a specific haplotype surrounding; this can explain the controversial results published so far about this variant. More importantly, we observed, that while a specific haplotype can confer risk for rheumatoid arthritis, the same haplotype tended to protect against the development of the other two diseases. The data presented here serve evidence for the need of haplotype analysis instead of just single standing SNP analysis when susceptibility to or protection against a certain disease are interpreted.

Abstract
Recently, evidence is emerging that inappropriate regulation of type 17 T helper cells (Th17) plays a fundamental role in the development of many autoimmune diseases including systemic lupus erythematosus (SLE). However, the role of Th17-related cytokines in SLE remains elusive. To further investigate the role and imbalance of Th17-related cytokines in the pathogenesis of SLE. A Quantitative RT-PCR Array (Human Th17 for Autoimmunity & Inflammation PCR Array) analyses were performed to study Th17-related genes expression in peripheral white blood cells of 25 new-onset patients with SLE and 15 healthy subjects. When gene expression for SLE patients was compared to the mean of normal controls, among the 84 target genes related to Th17 pathway, 7 (CXCL1, ICAM1, IL10, IL5, IL8, ISG20, JAK2,) were upregulated and 6 (CD28, CD40LG, S1PR1, IL17RE, IL23R, RORC) downregulated. However, comparisons of mRNA expression of Th17 related cytokines between lupus nephritis (LN) patients and SLE patients without nephritis (SLE non LN) showed no significant difference. In conclusion, SLE patients and normal controls showed different expression of a few genes in Th17 pathway, indicating that the pathway may be involved in the pathogenesis of SLE.

Abstract
The objective of this study was to elucidate whether polymorphisms of the interleukin 23 receptor gene (IL23R) are associated with susceptibility to systemic lupus erythematosus (SLE) in a Korean population. We recruited 602 SLE patients and 991 healthy controls. Seven single nucleotide polymorphisms (rs1004819, rs7517847, rs10489629, rs2201841, rs1343151, rs11209032, and rs1495965) were selected for genotyping among previously reported variants used in a genome-wide association study of inflammatory bowel disease. Polymorphic sites were genotyped using the TaqMan assay. The genotype distributions of IL23R polymorphisms and haplotypes were compared between the SLE patients and healthy controls using multiple logistic regression models. None of the IL23R genetic variants differed significantly between SLE patients and healthy controls, which suggests that IL23R polymorphisms play no role in the susceptibility to SLE in the Korean population.

Abstract
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by the production of antinuclear autoantibodies and the inflammatory infiltration of many organ systems. SLE is a complex disorder in which multiple genetic variants, together with environmental and hormonal factors, contribute to disease risk. In this article, we summarize our current understanding of the genetic contribution to SLE in light of recent genome-wide association studies, which have brought the total number of confirmed SLE susceptibility loci to 29. In the second section, we explore the functional implications of these risk loci and, in particular, highlight the role that many of these genes play in the Toll-like receptor and type I interferon signaling pathways. Finally, we discuss the genetic overlap between SLE and other autoimmune and inflammatory conditions as several risk loci are shared among multiple disorders, suggesting common underlying pathogenic mechanisms.

SUBJECTS We analysed 383 SLE patients and 253 controls for rs11805303, rs10889677, rs1004819, rs2201841, rs11209032, 11209026, rs10489629, rs7517847 and rs7530511 variants. METHODS The analysis was carried out using PCR-RFLP methods. Logistic regression analysis was used to compare the genotype distributions of the polymorphisms and haplotypes between the SLE patients and healthy controls. RESULTS We observed no significant difference of the examined variants between the patient and control groups. CONCLUSIONS Our results suggest that neither single nucleotide variants nor haplotypes of IL23R indicate susceptibility to developing SLE in the Hungarian population.

Abstract
Acquired aplastic anemia (AA) is a rare disease with a complex pathogenesis. In most cases, T cell-mediated immune destruction of hematopoietic cells results in peripheral blood pancytopenia and bone marrow hypoplasia. A subset of the heterodimeric interleukin-23 receptor gene (IL-23R) is significantly associated with autoimmune-mediated diseases. To examine whether IL-23R single nucleotide polymorphisms (SNPs) might contribute to AA, we selected three IL-23R SNPs with amino acid changes (rs11209026: p.Arg381Gln; rs41313262: p.Val362Ile; and rs11465797: p.Thr175Asn) and compared their frequencies in 279 AA patients and 184 ethnically matched healthy controls. The three SNP prevalences were similar between the AA patients and controls. The Arg381Gln variant, which has a strong protective effect against inflammatory bowel disease, showed no association with AA. Furthermore, IL-23 levels in sera were measured in the AA patients and in controls, and there were no significant differences among them. Our results indicate that these three IL-23R SNPs and serum IL-23 level have no apparent impact on susceptibility to AA.

Abstract
The aim of this study was to determine the potential role of three IRF3 gene polymorphisms (rs2304204, rs7251 and rs2304207) with systemic lupus erythematosus (SLE). Our study population consisted of 610 patients with SLE and 730 healthy controls. All individual were of Spanish Caucasian origin. The IRF3 polymorphisms were genotyped using a PCR system with pre-developed TaqMan allelic discrimination assay. No statistically significant differences were found when allele and genotype distribution of rs2304204, rs7251 and rs2304207 polymorphisms were compared between patients with SLE and controls [overall P values: rs7251, P = 0.06; rs2304204, P = 0.26 and rs2304207, P = 0.36, by chi-squared test on a 3 x 2 contingency table. Overall allelic P values: rs7251, P = 0.8, OR (95%CI) = 1.03 (0.87-1.22); rs2304204, P = 0.2, OR (95%CI) = 1.12 (0.93-1.34) and rs2304207, P = 0.8, OR (95%CI) = 1.02 (0.82-1.26)]. In addition, no evidence of association with haplotypes and clinical features of SLE was found. Our data suggest that the IRF3 polymorphisms do not appear to play a major role in the susceptibility or severity of SLE in a Spanish population.

Abstract
Background Association of the interleukin-23 receptor (IL23R) with inflammatory bowel disease (IBD) has been confirmed in several populations. IL23R also associates with psoriasis, suggesting that the gene may be an important candidate for many chronic inflammatory diseases. Methods We studied association of single-nucleotide variants in IL23R with IBD in Swedish patients, in both Crohn's disease (CD) and ulcerative colitis (UC) subsets. The same genetic variants were also studied in Finnish patients with psoriasis or celiac disease, and in Hungarian and Italian patients with celiac disease. Results Association of IL23R with IBD was replicated in our Swedish patients, and linkage and association of the IL23R region with psoriasis was found in the Finnish population. The IL23R region was also linked to celiac disease in Finnish families, but no association of IL23R variants with celiac disease was found in the Finnish, Hungarian or Italian samples. Conclusion Our study is the first to demonstrate association of IL23R with CD and UC in Swedish patients with IBD. It is also the first study to report linkage and association of the IL23R region with psoriasis in the Finnish population. Importantly, this is the first report of linkage of the IL23R region to celiac disease, a chronic inflammatory condition in which IL23R has not been previously implicated.

Abstract
The recent discovery of interleukin 23 (IL-23), its receptor, and the underlying signal transduction pathway has improved our understanding of cellular immunity. Several studies suggest that IL-23 is an essential promoter of chronic joint inflammation. In this report, we assess the possible association of interleukin 23 receptor (IL23R) polymorphisms and haplotypes with rheumatoid arthritis (RA). The study was conducted on 1,204 RA patients and 979 healthy controls. Seven polymorphisms were selected from previous IBD reports. The seven SNPs (rs1004819, rs7517847, rs10489629, rs2201841, rs1343151, rs11209032 and rs1495965) were genotyped using the TaqMan assay. Comparison of RA and control subjects revealed no statistically significant differences in the distribution of the IL23R genotypes and haplotypes. Our results clearly indicate that IL23R gene polymorphisms do not play a significant role in susceptibility to RA in the Korean population. Accordingly, we conclude that IL23R gene polymorphisms cannot be applied as an effective genetic marker for RA susceptibility.

Abstract
Osteonecrosis of the femoral head (ONFH) is known as death of the cellular portion of the femoral head due to an interruption in the vascular supply. The underlying pathophysiology regarding bone cell death remains uncertain. Recently, several studies have shown that autoimmune disorders were related to the development of osteonecrosis. This study investigated the genetic effects of Interleukin 23 receptor (IL23R) polymorphisms regarding the risk of ONFH. Ten SNPs were selected and genotyped in 443 ONFH patients and 273 control subjects in order to perform the genetic association analysis. It was found that polymorphisms of the IL23R gene (rs4655686, rs1569922 and rs7539625) were significantly associated with an increased risk of ONFH (P values; 0.0198-0.0447, OR; 1.30-1.49). Particularly, a stratified analysis based on etiology (alcohol, steroid or idiopathic) showed that the associations between these polymorphisms and ONFH were most significant in idiopathic ONFH patients (P values; 0.0001-0.0150, OR; 1.45-2.17). These results suggest that IL23R polymorphisms may play an important role in the development of ONFH.

Abstract
BACKGROUND Recent genomic surveys have identified IL23R and IL12B as susceptibility loci for inflammatory bowel disease (IBD). Our aim in the present study was to ascertain whether the IL23R and IL12B associations with IBD are also observed in our population, and to analyze possible genetic interactions between polymorphisms at IL12B and IL23R, ligand and receptor, respectively. METHODS In all, 707 IBD patients (344 with Crohn's disease and 363 with ulcerative colitis) and 547 healthy controls from the same ethnic origin (Caucasian Spaniards) were included in the present study. Two single nucleotide polymorphisms (SNPs) in IL23R (rs7517847 and rs11209026) and 2 in IL12B (rs3212227 and rs6887695) genes were analyzed by TaqMan technology. Genetic frequencies were compared with a chi-square test. Interaction between genes was analyzed by case-only comparisons. RESULTS The data show an association of both IL23R SNPs with overall IBD (statistically stronger, rs7517847; odds ratio [OR] = 0.79, 95% confidence interval [CI]: 0.67-0.94, minor allele frequencies: 0.355 in IBD patients versus 0.410 in controls; P = 0.005), somewhat stronger in Crohn's disease (OR = 0.74, 95% CI: 0.61-0.91) than in ulcerative colitis (OR = 0.84, 95% CI: 0.69-1.03). IL12B rs6887695 showed a weak association with IBD (OR = 1.24, 95% CI: 1.04-1.47, minor allele frequencies: 0.375 in IBD patients versus 0.326 in controls, P = 0.012), stronger in UC (OR = 1.31, 95% CI: 1.07-1.60, P = 0.007). No statistically significant differences were apparent when patients were stratified according to clinical characteristics. No interaction was observed between any of the polymorphisms studied at IL12B and IL23R. CONCLUSIONS Our study confirms the association of IL23R and IL12B with IBD in the Spanish population, but no interaction between either loci could be detected.

Abstract
Recently, a genome-wide association study identified the interleukin-23 receptor gene (IL23R) as an inflammatory bowel disease (IBD) associated gene. Given the involvement of IL23R in T-cell regulation, we decided to test whether this gene is associated with rheumatoid arthritis (RA). Eight IL23R gene polymorphisms (rs1,004,819, rs7,517,847, rs10,489,629, rs11,209,026, rs1,343,151, rs10,889,677, rs11,209,032, and rs1,495,965) were selected among the 10 most associated SNPs from the IBD study. A total of 322 RA patients and 342 healthy controls were genotyped for the selected SNPs using a Taqman 5' allelic discrimination assay. We did not find statistically significant differences when we compared allele and genotype frequencies between RA patients and controls for none of the IL23R gene polymorphisms under study. We did not observe significant differences when RA patients were stratified according to their clinical and demographic features. We conclude that the IL23R gene does not seem to be associated with RA predisposition in a Spanish population.
