Previous studies indicated that single-nucleotide polymorphisms (SNPs) of interferon gamma (IFNG) and IFNG receptor 1 (IFNGR1) may be involved in the pathogenesis of pulmonary tuberculosis (PTB) in different populations. In order to further explore the results in a Chinese Han population, this study was designed to investigate potential associations between the polymorphisms in IFNG and IFNGR1 and susceptibility to latent tuberculosis infection (LTBI) and/or PTB in a Chinese Han population. A total of 209 PTB, 173 LTBI, and 183 healthy control subjects (HCS) were enrolled in our study. Genotyping was conducted using an improved multiplex ligase detection reaction (iMLDR). We performed a logistic regression including sex and age as covariates to test the effect of alleles/genotypes on LTBI and/or TB. All six markers studied in IFNG and IFNGR1 conformed to the Hardy–Weinberg equilibrium (HWE). The IFNG rs1861494 was significantly associated with LTBI in recessive model, and the CC+CT genotype decreased risk of LTBI by 50% (P=0.046, OR=0.50, 95%CI: 0.25-0.99). The IFNGR1 rs2234711 was significantly associated with LTBI, and allele A increased the risk of LTBI by 55% (P=0.047, OR=1.55, 95%CI: 1.00-2.40). In the present study, we found that IFNG and IFNGR1 polymorphisms were associated with LTBI.

Background/Aims: The association between ACYP2(Acylphosphatase 2) polymorphisms and immunoglobulin A nephropathy (IgAN) risk in the Chinese Han population remains unclear. We aimed to evaluate the association between ACYP2 polymorphisms and IgAN risk by performing a case-control study. Methods: Eleven ACYP2 single nucleotide polymorphisms (SNPs) from 416 IgAN patients and 495 healthy controls were genotyped using the Sequenom MassARRAY platform. Odds ratio (OR) and 95% confidence interval (CI) were calculated to evaluate the association of ACYP2 polymorphisms with IgAN risk. Results: We observed that rs843720 was significantly associated with an increased risk of IgAN (allele G: OR = 1.23, 95% CI: 1.01–1.49, p = 0.036; dominant model: OR = 1.55, 95% CI: 1.01–2.37, p =0.044; log-additive model: OR = 1.43, 95% CI: 1.04–1.95, p = 0.026) before Bonferroni correction. The SNP rs12615793 was also significantly associated with an increased IgAN risk in the recessive model (OR = 3.33, 95% CI: 1.05–10.51, p = 0.042) before Bonferroni correction. Conclusion: These findings suggested that polymorphisms (rs843720 and rs12615793) of ACYP2 may be pivotal in the development of IgAN. However, more functional and association studies with larger sample sizes should be performed to further validate our results in the future.

Objective. Osteoarthritis (OA) is a complex arthritic condition in which the genetic factor plays a major role. One of the candidate genes of is the ADAM12 gene, but no consistency has been reached till now. This study aims to investigate the potential role of four single nucleotide polymorphisms (SNPs) of the ADAM12 gene in susceptibility to knee OA and its progression in Chinese Han population.Methods. The rs1278279, rs3740199, rs1044122, and rs1871054 polymorphisms were genotyped and compared in a population based cohort consisting of 164 OA subjects and 200 age- and gender-matched controls.Results. The SNP rs1871054 was found with increased risk of OA susceptibility in comparing the genotype frequencies between the case and control groups no matter for which model of comparison (allele level, dominant model, recessive model, and extreme genotype model). Additionally, the SNP rs1871054 was found associated with increased OA severity according to the K/L grade.Conclusion. In summary, we have identified that the rs1871054 variant within the ADAM12 gene is a risk factor for increased osteoarthritis susceptibility and severity.

ObjectivesSystemic sclerosis (SSc) is an uncommon autoimmune disease that varies with ethnicity. Single nucleotide polymorphisms (SNPs) in the GTFSI, NFKB1, and TYK2 genes have been reported to be associated with SSc in other populations and in individuals with various autoimmune diseases. This study aimed to investigate the association between these SNPs and susceptibility to SSc in a Chinese Han population.MethodA case-control study was performed in 343 patients with SSc and 694 ethnically matched healthy controls. SNPs in GTF2I, NFKB1, and TYK2 were genotyped using a Sequenom MassArray iPLEX system. Association analyses were performed using PLINK v1.90 software.ResultOur study demonstrated that the GTF2I rs117026326 T allele and the GTF2I rs73366469 C allele were strongly associated with patients with SSc (P = 6.97E-10 and P = 1.33E-08, respectively). Patients carrying the GTF2I rs117026326 TT genotype and the GTF2I rs73366469 CC genotype had a strongly increased risk of SSc (P = 6.25E-09 and P = 1.67E-08, respectively), and those carrying the NFKB1 rs1599961 AA genotype had a suggestively significantly increased risk of SSc (P = 0.014). Moreover, rs117026326 and rs73366469 were associated with SSc in different genetic models (additive model, dominant model, and recessive model) (P < 0.05) whereas rs1599961 was associated with SSc in the dominant genetic model but not in the addictive and recessive models (P = 0.0026). TYK2 rs2304256 was not significantly associated with SSc in this study.ConclusionGTF2I rs117026326 and rs73366469 SNPs were strongly associated with SSc in this Chinese Han population. NFKB1 rs1599961 showed a suggestive association with SSc, and no significant association was found between TYK2 rs2304256 and SSc in this Chinese Han population.

Aim. To clarify the association between the single nucleotide polymorphisms (SNPs) in the NLRP1 and NLRP3 and Psoriasis Vulgaris (PsV) in the Chinese Han population. Methods. We genotyped eight SNPs, four from NLRP1 (rs8079034, rs11651270, rs11657747, and rs878329) and NLRP3 (rs7512998, rs3806265, rs10754557, and rs10733113) each in 540 patients with PsV and 612 healthy controls in the Chinese Han population using an improved multiplexed ligation detection reaction (iMLDR) method. The genotype and haplotype frequencies were analyzed using a case-control study design. Results. We identified two SNPs, rs3806265 and rs10754557, in NLRP3 that were significantly associated with PsV. The genotype distribution of the rs3806265 SNP was significantly different between cases and controls (p=0.0451; OR = 0.791; 95% CI = 0.627–0.998). In the recessive model, the genotype distribution of the rs10754557 SNP was significantly different between cases and controls (p=0.0344; OR = 1.277; 95% CI = 0.987–1.652). The haplotype analysis of rs3806265 and rs10754557 also presented a significant association of TA haplotype with PsV (χ2=4.529; p=0.033). Conclusion. NLRP3 may play a role in PsV susceptibility in the Chinese Han population.

Objective To investigate the association between three single nucleotide polymorphisms (SNPs) of the ATP-binding cassette (ABC) gene family and susceptibility to type 2 diabetes mellitus in a Chinese Han population. Methods A total of 1086 type 2 diabetes patients and 1122 healthy controls were included in this retrospective study. Three genetic variants, rs1800977 and rs4149313 in ABCA1, and rs1128503 in ABCB1 were included in the study. Susceptibility to type 2 diabetes was evaluated under three genetic models. Results A significant association between rs1800977 and type 2 diabetes was identified in three different genetic models (TT vs CC, odds ratio [OR] = 0.611 [95% confidence interval (CI), 0.469–0.798]; T vs C, OR = 0.841 [95% CI, 0.745–0.950]; and the recessive model, OR = 0.606 [95% CI, 0.474–0.774]). Additionally, a significant association between rs4149313 and type 2 diabetes was identified in three different genetic models (AA vs GG, OR = 0.467 [95% CI, 0.326–0.670]; A vs G, OR = 0.819 [95% CI, 0.717–0.935]; and the recessive model, OR = 0.478 [95% CI, 0.336–0.680]). Conclusion We found that SNPs rs1800977 and rs4149313 in ABCA1 are significantly associated with susceptibility to type 2 diabetes in a Chinese population, although this should be confirmed in a larger study.

Abstract Objective: Genetic factors are involved in the occurrence, development, and progression of essential hypertension (EH). To study the association between single nucleotide polymorphisms (SNPs) of the rs6435156 and rs1048829 loci of the bone morphogenetic protein receptor type 2 (BMPR2) gene, the rs121909287 and rs121909284 loci of the activin receptor-like kinase 1 (ACVRL1) gene, and the rs397514716 and rs121918359 loci of the mothers against decapentaplegic homolog 9 (SMAD9) gene with the risk of EH in the Chinese Han population. Materials and methods: A total of 460 EH patients and 460 healthy controls were recruited for the study. Genomic DNA of white blood cells was extracted, and the genotypes were analyzed by Sanger sequencing after polymerase chain reaction amplification. Multi-factor dimensionality reduction (MDR) was used to analyze the effect of gene–environment interactions on EH risk. Results: The risk of EH increased in the BMPR2 gene rs6435156 locus dominant model (adjusted odds ratio [OR] = 1.572, 95% confidence interval [CI]: 1.385–1.765, P<0.001) and recessive model (adjusted OR = 1.926, 95% CI: 1.693–2.067, P<0.001). The risk of EH increased in the rs1048829 recessive model (adjusted OR = 1.444, 95% CI: 1.142–1.696, P=0.003). The risk of EH increased in the recessive model of the ACVRL1 gene rs121909287 locus (adjusted OR = 1.403, 95% CI: 1.101–1.660, P=0.008). The risk of EH increased in the SMAD9 gene rs397514716 locus dominant model (adjusted OR = 1.370, 95% CI: 1.183–1.559, P<0.001) and recessive model (adjusted OR = 1.803, 95% CI: 1.470–1.983, P<0.001). The CG haplotype of the rs6435156 and rs1048829 loci of the BMPR2 gene, the CC haplotype of the ACVRL1 gene rs121909287 and rs121909284 loci, and the CC haplotype of the rs397514716 and rs121918359 loci of the SMAD9 gene were factors that protect against EH, whereas the TT haplotype of the rs6435156 and rs1048829 loci in the BMPR2 gene was a risk factor for EH. MDR analysis showed that the BMPR2 gene rs6435156 locus TT genotype carriers, the SMAD9 gene rs397514716 locus TT genotype carriers, and alcohol drinkers had the highest EH risk (OR = 4.523, 95% CI: 2.235–6.871, P<0.001). Conclusion: The SNPs of the rs6435156 and rs1048829 locus in the BMPR2 gene, the rs121909287 loci in the ACVRL1 gene, and the rs397514716 locus in the SMAD9 gene were associated with a risk of EH in Han Chinese.

Objective This study was performed to investigate the association between genetic variation in SMAD3 and hip osteoarthritis (OA) in a Chinese Han population. Methods The frequency of two single nucleotide polymorphisms of SMAD3, rs1470002 and rs12901499, was examined in 500 patients with hip OA and 1080 healthy controls in a Chinese Han population. Further analysis was performed according to sex and age. Results We detected statistically significant differences in the allele frequency and genotype between the hip OA and healthy control groups. The frequency of the GA+GG and GA genotypes of rs12901499 and the G variant were much higher in patients with hip OA than in healthy controls. This association was also present when the participants were stratified by sex and age. However, there was no significant association between the risk of hip OA and the presence of rs1470002 GA, AA, or GA+AA genotypes, even after sex- and age-stratified analysis. Conclusions The SMAD3 SNP rs12901499 GA genotype and G variant may increase the risk of hip OA in Chinese Han patients.

Background: MicroRNA (miRNA) is a pivotal regulator of the occurrence and development of various cancers. And gastric cancer (GC) is one of the most common and deadly cancers in the world. The aim of this study is to explore whether the microRNA-143 host gene (miR-143HG) polymorphisms are correlated with the risk of GC. Methods: 5 single-nucleotide polymorphisms (SNPs) were genotyped among 506 patients and 500 healthy controls in Han Chinese population. Multiple genetic models, stratification analysis and haplotype analysis were used to evaluate the association between miR-143HG polymorphisms and GC risk by calculating odds ratios (ORs), 95% confidence intervals (CIs). Results: Our results indicated that rs11168100 was associated with decreased risk of GC under the Codominant model (OR = 0.67, 95%CI = 0.52-0.88, p = 0.003), and under the Dominant model (OR = 0.72, 95%CI = 0.56-0.92, p = 0.009). Rs353300 was associated with increased risk of GC under the Recessive model (OR = 1.41, 95%CI = 1.06-1.87, p = 0.017). Further, rs11168100 and rs353300 were correlated with the susceptibility of GC (age > 60 years), and three SNPs (rs12654195, rs353303, and rs353300) were related with the risk of GC (age ≤ 60 years). In addition, two SNPs (rs12654195 and rs11168100) were found to be associated with decrease in the susceptibility of GC in the female subgroup. Rs353300 represented two-sided roles in the occurrence and development of GC in female. Finally, rs3533003 was associated with decreased risk of GC in stratified analysis of lymph node metastasis. Conclusion: For the first time, our results provide some evidence on the polymorphisms of miR-143HG associated with GC risk in the Chinese Han population.

Abstract A limited number of genome-wide association studies (GWAS) have shown that CACNA1C is a potential candidate gene for insomnia. The present study sought to investigate the association of CACNA1C gene polymorphisms and insomnia in a Chinese Han population. Twenty-one single nucleotide polymorphisms (SNPs) in the CACNA1C were genotyped by using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) with a Sequenom MassARRAY system in 205 patients with insomnia and 154 healthy controls. Data from all participants were systematically collected. Association of the polymorphisms with insomnia was evaluated by statistical analysis. Linkage disequilibrium (LD) and haplotype analysis were performed with Haploview v4.2 software. After adjustment for multiple comparisons and gender, age, body mass index (BMI), hypertension and glycated hemoglobin (HbA1c), only the rs2302729 in the recessive model (adjusted odds ratio [AOR]= 0.414, 95%CI= 0.220-0.771, P= 0.004) related to insomnia achieved significance by the false discovery rate (FDR) Benjamini and Hochberg (BH) criterion. The haplotypes rs2302729-rs1051375, CA and TG were significantly associated with insomnia (P<0.05). Our findings contributed important evidence for the confirming of CACNA1C as a susceptibility gene for insomnia in the samples of Chinese Han population.

Abstract Background The study aimed to evaluate the relationship of IL-1B/IL-1RN polymorphisms to the predisposition of head and neck cancer (HNC) in a Chinese Han population. Methods Nine single-nucleotide polymorphisms (SNPs) in IL-1B/IL-1RN were genotyped based on Agena MassARRAY platform. Logistic regression models were used to analyze the genetic association between these SNPs and HNC risk by calculating odds ratios (ORs) and 95% confidence intervals (CI). Haplotype analysis were performed using Haploview program and logistic regression model. Results The genetic association between rs1143643 in IL-1B and the higher risk of HNC was found (OR = 1.23, 95% CI 1.04–1.46) in the overall. IL-1RN rs17042888 was related to a reduced risk of HNC in the subjects aged > 46 years (OR = 0.70, 95% CI: 0.50–0.98) and in females (OR = 0.71, 95% CI 0.52–0.98), while rs1143643 increased the predisposition of HNC among females (OR = 1.76, 95% CI 1.13–2.74). Furthermore, rs1143643 had an increased susceptibility to thyroid carcinoma (OR = 1.61, 95% CI 1.10–2.34). Moreover, compared with stage I–II, the frequency of IL-1RN rs452204-AG genotype was lower in patients with stage III–IV. Conclusions IL-1B (rs1143643) and IL-1RN (rs17042888 and rs452204) polymorphisms might be related to the individual susceptibility of HNC in the Chinese Han population. These results might help to improve the understanding of IL-1B and IL-1RN genes in the occurrence of HNC.
