Interleukin-17A gene polymorphism is associated with susceptibility to gastric cancer

We conducted a study to investigate the role of three common SNPs in the IL-17A and IL-17F genes (rs2275913G>A, rs3748067C>T and rs763780T>C) in the development of gastric cancer, and their interaction with H.pylori infection. A total of 326 patients with gastric cancer and 326 control subjects were consecutively recruited between May 2012 and May 2014. Genotyping of IL-17A rs2275913G>A and rs3748067C>T and IL-17F rs763780T>C was performed in a 384-well plate format on the Sequenom MassARRAY platform. By logistic regression analysis, individuals carrying the GA and AA genotypes of IL-17 rs2275913G>A were significantly associated with an increased risk of gastric cancer when compared with GG genotype, and the adjusted Ors (95% CI) were 1.46 (1.03-2.06) for GA genotype and 2.57 (1.51-4.43) for AA genotype. We observed that the GA+AA genotype of rs2275913 was associated with an increased risk of gastric cancer among H.pylori infection subjects (OR=2.21, 95% CI=1.29-3.79). In conclusion, we found that there was a significant association between L-17A rs2275913G>A polymorphism and increased gastric cancer risk, especially in H.pylori infection subjects.     

Association between interluekin-17 gene polymorphisms and the risk of cervical cancer in a Chinese population

We conducted a study to analyze the association of three common SNPs of IL-17A rs2275913 and rs3748067 and IL-17F rs763780 gene polymorphisms with the risk of cervical cancer in a Chinese population. Our study included 352 cervical cancer patients and 352 controls between January 2013 and December 2014. Genotyping of IL-17A rs2275913 and rs3748067 and IL-17F rs763780 genes was performed by multiplex PCR assays using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). By χ² test, there was significantly difference in the genotype distribution of IL-17A rs2275913 between cervical cancer patients and control subjects (χ²=11.45, P=0.003). By conditional logistic regression analysis, we found that individuals with the GA and AA genotypes were associated with an increased risk of cervical cancer when compared with the GG genotype in codominant model, and the adjusted Ors (95% CI) were 1.57 (1.13-2.18) and 2.01 (1.15-3.49), respectively. In dominant model, we found that the GA+AA genotype of rs2275913 was correlated with a moderate increased risk of cervical cancer compared with the GG genotype (OR=1.64, 95% CI=1.20-2.24). We only found significant interaction between rs2275913 polymorphism and HPV-16 or 18 infection in the risk of cervical cancer (P for interaction <0.05). In conclusion, our study suggests that IL-17A rs2275913 polymorphism may affect the development of cervical cancer in codominant and dominant models, and this gene polymorphism has interaction with HPV-16 or 18 infection.     

StIL-17 gene polymorphisms in the development of pulmonary tuberculosis

We conduct a case-control study to explore the possible association between IL-17 gene polymorphisms and development of TB. Methods: The study population comprised 428 TB subjects and 428 control subjects between January 2013 and June 2014. Genotyping analyses of IL-17A rs2275913 and rs3748067 and IL-17F rs763780 and rs9382084 were analyzed using polymerase chain reaction-restriction fragment length of polymorphism (PCR-RFLP). Results: The TB cases were more likely to have a habit of smoking when comparing with controls. By conditional logistic regression analysis, individuals carrying CC genotype of rs763780 were more likely to have a significantly increased risk of TB when compared with TT genotype. The OR (95% CI) for CC genotype of rs763780 was 2.98 (1.58-5.92). Conclusion: In conclusion, we suggest that rs763780 play a critical role in the etiology of TB. These findings could be helpful in identifying individuals at increased risk for developing TB.     

Association between interleukin-17 gene polymorphisms and risk of coronary artery disease

We conducted a case-control study to estimate the association between IL-17A rs2275913, rs3819025 and rs3748067 polymorphisms and development of coronary artery disease. A total of 415 patients with coronary artery disease and 448 health controls were recruited during the period of March 2013 and October 2014. Genotyping of IL-17A rs2275913, rs3819025 and rs3748067 were analyzed by polymerase chain reaction coupled with restriction fragment length polymorphism. By logistic regression analysis, we found that individuals with the AA genotype (OR, 2.18; 95% CI, 1.35-3.56) and the GA+AA genotype (OR, 1.39, 95% CI, 1.06-1.84) of rs2275913 were associated with an increased risk of coronary artery disease when compared with the GG genotype. Individuals carrying the GA+AA genotype of rs2275913 were more likely to have a higher risk of coronary artery disease in those with hypertension and smoking habit, and the adjusted ORs (95% CI) were 3.92 (2.13-6.82) and 2.74 (1.71-4.40). In conclusion, we suggest that individuals with the AA genotype and the GA+AA genotype of rs2275913 are associated with an increased risk of coronary artery disease, especially in those with hypertension and smoking habit.     

Interleukin-17A rs2275913, Interleukin-17F rs763780 and rs2397084 gene polymorphisms as possible risk factors in Juvenile lupus and lupus related nephritis

There are no reports about the association of interleukin (IL)-17A and IL-17F gene polymorphism and susceptibility to pediatric systemic lupus erythematosus (pSLE). Objective: To examine the possible role of IL-17A rs2275913, IL-17F rs763780 and rs2397084 polymorphisms as risk factors for pSLE in a cohort of Egyptian children and to investigate their association with the clinico-pathological features including lupus nephritis (LN). Methods: Typing of IL-17A and IL-17F polymorphisms was done using restriction fragment length polymorphism for 115 children with SLE and 259 age- and sex-matched healthy controls. Results: No significant differences were found between pSLE patients and healthy controls for the allele and genotype frequencies of IL-17A rs2275913, IL-17F rs763780 and rs2397084 (p?>?0.05). However, the combined genotype GGAGAA and the haplotype GGA had significant association with pSLE (p_c?=?0.042 and <0.001, respectively). The AA genotype of IL-17F rs763780 is more frequent in female patients (p?=?0.002) and the AA genotype of IL-17F rs2397084 is more associated with positivity of ds-DNA (p?=?0.007). No more associations were found for the demographic and clinical data of pSLE patients including risk of LN development, risk of non-remission, overall survival, activity and chronicity indices. Conclusion: The GGAGAA combined genotype and the GGA haplotype of IL-17A rs2275913, IL-17F rs763780 and rs2397084 can be considered risk factors for the development of SLE in Egyptian children. IL-17A rs2275913, IL-17F rs763780 and rs2397084 are not related to the LN development, SLE disease activity or overall survival.     

Association of interleukin-17A and -17F gene single-nucleotide polymorphisms with autoimmune thyroid diseases

Th17 lymphocyte and its relative cytokines have been shown to play an important role in autoimmune thyroid diseases (AITD). The aim of this study was to investigate the association between IL-17A and IL-17F gene polymorphisms and two main types of AITD, Graves' disease (GD) and Hashimoto's thyroiditis (HT). Whole blood specimens and clinical data were collected from 508 AITD patients (326 with GD and 182 with HT) and 224 age- and gender-matched healthy controls, respectively. IL-17A (rs2275913, rs8193037, rs3819025) polymorphism was determined using DNA sequencing method and IL-17F/rs763780 polymorphism was assayed by polymerase chain reaction-restriction fragment length polymorphism (PCR -RFLP). The results indicated that the frequencies of IL-17F/rs763780 genotypes in patients with GD and HT differed significantly from their controls (P = 0.013 and P = 0.005, respectively); the G allele frequencies were also significantly higher in the patient groups than the control groups (P = 0.002 and 0.001, respectively). For IL-17A/rs2275913 and rs8193037 SNP, no significant difference was observed in patients with either GD or HT compared to the control groups (P>0.05). Interestingly, for rs3819025, the frequency of A allele was lower in patients with GD than controls (P = 0.011). The frequencies of haplotype AGGG and GGGG in patients with GD and HT were significantly higher than in controls (P = 0.012, P = 0.019, P = 0.017 and P = 0.029, respectively). In conclusion, the results indicate that IL-17F/rs763780 polymorphisms may affect the susceptibility to AITD, and IL-17A/rs3819025 SNP is likely a protective factor to GD in the Chinese population.     

Associations between interleukin 17A and 17F polymorphisms and asthma susceptibility: A meta-analysis

Owing to their role in inflammatory reactions and immunological responses as well as their chromosomal location, interleukin (IL) 17A and 17F are regarded as candidate causal genes associated with asthma. The aim of this study was to determine whether IL17 polymorphisms are associated with susceptibility to asthma. We used the PubMed/Medline and Embase databases to search for studies reporting IL17 polymorphisms in patients with asthma and healthy controls. Meta-analyses were conducted to determine the associations between IL17A rs8193036 (−737C/T), rs2275913 (−197G/A), rs3819024 (A/G), rs3748067 (C/T), and rs4711998 (A/G) and IL17F rs763780 (7488A/G), rs2397084 (T/C), rs1889570 (C/T), rs11465553 (G/A), and rs1266828 (T/C) polymorphisms and asthma susceptibility. A total of 20 studies were included in this meta-analysis. Our results revealed the IL17A rs8193036 CC genotype was associated with asthma susceptibility (odds ratio [OR] = 1.490, 95% confidence interval [CI] = 1.027–2.161, p = .036). However, stratification by ethnicity indicated no association between this polymorphism and asthma in European and Asian subjects. Furthermore, no association was found between this polymorphism and asthma using the allele contrast, dominant or homozygous contrast models. No evidence of an association was found between any of the other IL17A and IL17F polymorphisms and asthma susceptibility in this meta-analysis. This meta-analysis showed that, among the studied polymorphisms, only the CC genotype of IL17A rs8193036 is associated with asthma susceptibility.

Role of gene polymorphisms/haplotypes and serum levels of interleukin-17A in susceptibility to viral myocarditis

Interleukin-17A (IL-17A) has been implicated in the pathogenesis of viral myocarditis (VMC). However, the role of IL-17A polymorphisms in susceptibility to VMC has not been reported to date. The aim of this study was to explore the association between IL-17A variants as well as serum IL-17 levels with VMC. Three single-nucleotide polymorphisms (SNPs) (rs2275913, rs3819025, and rs3748067) were analyzed by the polymerase chain reaction-restriction fragment length polymorphism method in 236 VMC patients and 259 controls from China. Serum IL-17A levels were measured by enzyme-linked immunosorbent assay kits. Multivariable logistic regression analysis that the rs2275913 AA genotype and the haplotype -197A/+45G/+1249G (AGG) were associated with an increased risk of VMC (all P?<?0.05). Consistent with these findings, the rs2275913 AA genotype was linked to higher serum IL-17A compared to GG/AG genotype (all P?<?0.001). We observed no associations between the other two SNPs and risk of VMC. Serum IL-17A levels were significantly higher in the VMC group than controls (P?<?0.001) and gradually increased with the increase of New York Heart Association grade in VMC patients (P?<?0.05). Spearman correlation test revealed that the serum IL-17A level was correlated with the cardiac damage and left ventricular systolic functions among VMC patients (all P?<?0.05). Our study reveals that IL-17A expression may contribute to the development and severity of VMC. The SNP rs2275913 in the IL-17A gene might exert influence on susceptibility to VMC via linking with the serum IL-17A level.     

Association of single nucleotide polymorphisms in interleukin 12 (IL-12A and -B) with asthma in a Chinese population

Increasing evidence has indicated that genetic variants may contribute to immune dysregulation and susceptibility to noninfectious inflammatory diseases. Cytokines, including interleukin 12 (IL-12), play a key role in the regulation of the immune system. The aim of this study was to investigate whether single nucleotide polymorphisms (SNP) in IL-12A and IL-12B were associated with asthma in a Chinese population. Genotype characteristics were determined in 197 asthma patients and 369 controls by the polymerase chain reaction-restriction fragment length polymorphism method and DNA sequencing assay. The genotype and allele frequencies of IL-12A rs568408 demonstrated significant differences between cases and controls (p < 0.001). The AC genotype of rs3212227 was associated with a significantly decreased risk of asthma compared with the AA genotype (p = 0.036). The subjects carrying combined genotypes (rs568408 AG and rs3212227 AC/CC) at both loci had a 2.05-fold increased asthma risk compared with those carrying all other genotypes (p = 0.001). In contrast, individuals carrying combined genotypes of rs568408 GG and rs3212227 AC/CC were associated with a significantly decreased risk of asthma compared with those carrying the combined genotypes of rs568408GG and rs3212227AA (p = 0.009). No significant difference was reported for rs2243115 between cases and controls. These results suggest that the SNPs in IL-12A rs568404 and IL-12B rs3212227 may individually and jointly contribute to the risk of asthma in a Chinese population.     

The Influence of Polymorphisms of Interleukin-17A and Interleukin-17F Genes on the Susceptibility to Ulcerative Colitis

We investigated the association between ulcerative colitis (UC) and polymorphisms of IL-17A (rs2275913, G-197A) and IL-17F (rs763780, 7488T/C) genes. We employed the multiplex PCR-SSCP method to detect gene polymorphisms. Both the numbers of -197A (IL-17A) and 7488T (IL-17F) alleles were significantly correlated to the development of UC. The frequencies of -197A/A and 7488T/T genotypes in the UC group were significantly higher than those in the non-UC group. An adjusted analysis revealed that -197A and 7488T alleles were independent risk factors for the developing UC. In addition, both polymorphisms were significantly associated with the pancolitis phenotype. Furthermore, -197A allele was significantly correlated to the chronic relapsing phenotype and -197A/A homozygote was more frequent in steroid-dependent cases, whereas 7488T allele was correlated with the chronic continuous phenotype. Our results provided the first evidence that -197A (IL-17A) and 7488T (IL-17F) alleles may influence the susceptibility to and pathophysiological features of UC independently.     

Polymorphisms in Th17-related genes and the pathogenesis of autoimmune thyroid disease

Abstract

The prognosis of autoimmune thyroid disease (AITD) including Graves’ disease (GD) and Hashimoto’s disease (HD) is difficult to predict. We previously suggested that Th17 cells may be associated with the pathogenesis of AITD. However, the association between gene polymorphisms in Th17-related genes and the prognosis of AITD was not clarified. To clarify this association, we genotyped 12 polymorphisms in 11 Th17-related genes (IL1Ra, IL6R, IL17R, IL21R, IL23R, CCR6, SOCS3, RORC, IL17A, IL17F and IL21) in 142?HD patients including 58 patients with severe HD and 48 patients with mild HD, 170 patients with GD including 81 patients with intractable GD and 49 patients with GD in remission, and 84 healthy volunteers. The frequency of the IL17F rs763780 T allele was higher in patients with severe HD than in patients with mild HD (p?=?.008). The frequency of the IL17R rs9606615 T allele was higher in patients with HD than in normal subjects (p?=?.011). The frequencies of the SOCS3 rs4969170 AA genotype, CCR6 rs3093024 AA genotype, and IL21 rs907715 AA genotype were higher in patients with intractable GD than in patients with GD in remission (p?=?.035, p?=?.002 and p?=?.030, respectively). In conclusion, IL17R rs9607715 and IL17F rs763780 polymorphisms are associated with the susceptibility and severity of HD, respectively. IL21 rs907715, SOCS3 rs4969170 and CCR6 rs3093024 polymorphisms are associated with the intractability of GD.

Asthma and atopy are associated with chromosome 17q21 markers in Chinese children

Background:  Single-nucleotide polymorphism (SNP)-based genome-wide association study revealed that markers on chromosome 17q21 were linked to childhood asthma but not atopy in Caucasians, with the strongest signal being detected for the SNP rs7216389 in the ORMDL3 gene. Such association was unknown in Chinese. This study delineated the allele and genotype frequencies of 10 SNPs at chromosome 17q21, and investigated the relationship between these SNPs and asthma and plasma IgE in southern Chinese children.
Methods:  Asthmatic children and non-allergic controls were recruited from pediatric clinics. Their plasma total and aeroallergen-specific IgE concentrations were measured by immunoassay. Ten SNPs on 17q21 region were genotyped by multiplex SNaPshot™, and their genotype associations with asthma traits analyzed using multivariate regression.
Results:  315 patients and 192 controls were enrolled. The allele frequency for C allele of rs7216389 varied significantly from 0.232 in our controls, 0.389 in Han Chinese to 0.536 in Caucasians. Asthma diagnosis was associated with rs11650680 and five other SNPs including rs7216389 ( P  =   0.019–0.034), whereas atopy was associated only with rs11650680 ( P  =   0.0004). Linear regression revealed the covariates for plasma total IgE to be significant for rs11650680 ( P  =   0.008–0.0002). Haplotypic associations were found with atopy and increased plasma total IgE, with the respective odds ratios and 95% confidence intervals for TTTCCGTT haplotype to be 0.21 and 0.09–0.52 ( P  =   0.0002) and 0.41 and 0.18–0.90 ( P  =   0.025).
Conclusion:  Childhood asthma and atopy are associated with chromosome 17q21 in Chinese, but such association may involve genes other than ORMDL3 in this region.     

Influence of IL17A polymorphisms (rs2275913 and rs3748067) on the susceptibility to ulcerative colitis

Interleukin-17A plays a role in tissue inflammation by inducing release of proinflammatory and neutrophil-mobilizing cytokines. We investigated the association between ulcerative colitis (UC) and polymorphisms of IL17A, rs2275913 (?197 G > A), and rs3748067 (*1249 C > T). The study was performed in 475 healthy subjects (controls) and 202 with UC (UC cases), including 113 controls and 64 UC cases from previous study. We employed the multiplex PCR-SSCP method to detect gene polymorphisms. The minor allele frequency of rs2275913 was significantly higher but that of rs3748067 was significantly lower in UC cases than controls. The rs2275913 minor homozygote (AA) had an increased risk of the development of UC, whereas rs3748067 minor carrier (CT + TT) had decreased risks for the development of UC. When compared with LR group (rs2275913 GG + GA with rs3748067 CT + TT), HR group (rs2275913 AA with rs3748067 CC) had a more increased risk of the development of UC (OR, 3.38; p = 0.0007). The polymorphisms of IL17A were associated with the noncontinuous and pancolitis phenotypes of UC. Our results suggest that IL17A polymorphisms (both rs2275913 and rs3748067) influence the susceptibility to and pathophysiological features of UC, coordinately.     

Investigation of the relationship between IL17A,IL17F and ILR1N polymorphisms and COVID-19 severity: The predictive role of IL17A rs2275913 polymorphism in the clinical course of COVID-19

Coronavirus disease 2019 (COVID-19) is an infectious respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although the mortality rate of the disease has been relatively under control as of 2022, more than 15 million confirmed COVID-19 cases have been detected in Turkey to date, causing more than 100,000 deaths. The clinical manifestation of the disease varies widely, ranging from asymptomatic to acute respiratory distress syndrome causing death. The immune response mechanisms have an important impact on the fine adjustment between healing and enhanced tissue damage. This study aims to investigate the relationship between the variants of the interleukin 1 receptor antagonist (IL1RN), interleukin 17A (IL17A), and interleukin 17F (IL17F) genes and COVID-19 severity. The study population comprised 202 confirmed COVID-19 cases divided into three groups according to severity. The IL1RN variable number of a tandem repeat (VNTR) polymorphism was genotyped by polymerase chain reaction (PCR), and IL17A rs2275913, IL17F rs763780 and rs2397084 polymorphisms were genotyped by the PCR-based restriction fragment length polymorphism method. Statistical analysis revealed a significant association between IL17A rs2275913 variant and COVID-19 severity. The AA genotype and the A allele of IL17A rs2275913 were found significant in the severe group. Additionally, we found a significant relationship between haplotype frequency distributions and severity of COVID-19 for the IL17F rs763780/rs2397084 (p = 0.044) and a combination of IL17F rs763780/rs2397084/ IL17A rs2275913 (p = 0.04). The CG and CGA haplotype frequencies were significantly higher in the severe group. IL17A rs2275913, IL17F rs763780 and rs2397084 variants appear to have important effects on the immune response in COVID-19. In conclusion, variants of IL17A rs2275913, IL17F rs763780 and rs2397084 may be the predictive markers for the clinical course and potential immunomodulatory treatment options in COVID-19, a disease that has placed a significant burden on our country.     

The polymorphisms of interleukin 17A (IL17A) gene and its association with pediatric asthma in Taiwanese population

Background:  The interleukin 17A ( IL17A ) gene, located on chromosome 6p and linked to asthma phenotype, is a highly potential candidate gene conferring asthma susceptibility. The purpose of this study was to investigate the genetic association between single nucleotide polymorphisms (SNPs) of IL17A and asthma in Taiwanese children.
Methods:  We selected and performed genotyping on nine SNPs that encompass the genomic region of IL17A in Taiwanese children with or without asthma. A total of 1939 subjects containing 1027 subjects in testing group and 931 subjects in validation group were recruited in this study.
Results:  After Bonferroni correction, SNP rs8193036 was found to have a weak association ( P  = 0.0074 × 9 = 0.066) in genotype frequency test. This association was confirmed by validation group. Logistic regression adjusted allergy comorbidity and gender showed a slightly weaker association.
Conclusions:  The results indicated an independent role of IL17A promoter polymorphism rs8193036 in the association with pediatric asthma in Taiwanese population.     

Maternal Genetic Variants of IL4/IL13 Pathway Genes on IgE With "Western or Eastern Environments/Lifestyles"

Purpose

We investigated maternal genetic effects of four IL-4/IL-13 pathway genes as well as their interactions with the "Western or Eastern lifestyles/environments" on IgE in Karelian children.

Methods

This study included 609 children and their mothers. Total IgE levels in children and mothers were measured and 10 single nucleotide polymorphisms (SNPs) in IL-4, IL-4Ra, IL-13, and STAT6 were genotyped in mothers and their children.

Results

The maternal G allele of IL-13 130 (rs20541) was significantly (P=0.001) associated with decreased IgE in children in the Karelian population (Pooling Finnish and Russian children), as well as in Finnish (P=0.030) and Russian children (P=0.018). The IgE levels were significantly (P=0.001) higher in Russian children whose mothers were homozygous for the G allele of the IL-4Ra 50 (rs1805010) SNP than that in Russian children of mothers who were AG heterozygotes or AA homozygotes. After accounting for children''s genotypes, we observed interactive effects on children''s IgE for maternal IL-13 130 genotypes (P=0.014) and maternal IL-4Ra 50 genotypes (P=0.0003) with "Western or Eastern" lifestyles/environments. With the adjustment for multiple comparisons using a false discovery rate (FDR) of 0.05, the interactive effect of the maternal IL-4Ra50 SNP was significant.

Conclusion

Maternal genetic variants in IL-4/IL-13 pathway genes, such as IL-13 130 and IL-4Ra50, influenced IgE levels in school children that were independent of the children''s genetic effects. These effects differ in "Western or Eastern" environments.     

Impact of the IL-17F,IL-23 and IL-23R on susceptibility and phenotype of systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a disease characterized by excessive proinflammatory cytokine production and damage to multiple organ systems. To investigate the potential association between cytokine gene polymorphisms and SLE, we performed a case-control study based on Polish population. SLE patients and controls, were examined for IL-23A rs11171806?G/A and IL-23R (rs1884444?G/T, rs10489629?G/A) by TaqMan SNP genotyping assay, for IL-17F rs763780 A/G and rs2397084A/G using the PCR– RFLP method. An increased frequency of AG genotype as well as G allele of the IL-17F rs763780 was found in patients with SLE, as compared with healthy subjects (OR?=?3.947; p?=?0.001 and OR?=?3.538; p?=?0.002, respectively). Frequencies of the rs1884444 TT genotype (OR?=?138.1) and the rs1884444 T allele (OR?=?2.176) were also higher in SLE patients (both p?0.0001). Overall, weak LD was observed between the IL-17F rs763780 A/G and rs2397084 A/G polymorphisms (D'-0.003, r² – 0.000). From four possible haplotypes, frequencies of AG showed differences between both examined groups (p?0.0001). We also observed a weak LD between the IL-23R rs10489629G/A and rs1884444?G/T (D'-0.199, r² –0.026). The genotype–phenotype analysis showed significant association between the IL-17F rs2397084 and mean value of the hemoglobin (p?=?0.01), the IL-17F rs763780 and age (p?=?0.008) and lupus anticoagulant (p?=?0.09), the IL-23 rs11171806 and urea (p?=?0.08) and C3 complement (p?=?0.03), and the IL-23R rs1884444?G/T and activated partial thromboplastin time (p?=?0.06). Present findings indicated that IL-17F rs763780 A/G and IL-23R rs1884444?G/T polymorphisms may be involved in susceptibility to SLE in the Polish population.
