Numerous linkage and association studies have been performed to identify genetic predispositions to schizophrenic (SCZ) in
different populations, but its genetic basis remains unclear. Some findings may provide a clue in understanding the association
between abnormal immunity and SCZ. MicroRNA (miRNA) involves in regulating both schizophrenic and immunity as previous reported.
And single nucleotide polymorphisms (SNPs) within miRNAs can change their characteristics, resulting in functional and/or
phenotypic changes. So two SNPs (hsa-pre-mir-146a rs2910164 G>C and hsa-mir-499 rs3746444 T>C) at two miRNAs, were genotyped
to demonstrate their association with susceptibility to SCZ. Polymorphisms were analyzed among 268 Chinese schizophrenic patients
and 232 healthy controls by PCR-RFLP and validated by sequencing. No association was found between the two polymorphisms and
SCZ either in cases or in controls. SCZ patients with family history showed significant increase of the G allele frequency
of rs2910164 in comparison to those without (P = 0.018). The CC genotype frequency of rs3746444 was also higher in the patients having hallucinations than those without
hallucinations (P = 0.012). In addition, patients carrying CC genotype of rs3746444 were more likely to be lack of motivation in comparison
to normal controls (P = 0.042). Allele and genotype frequency of rs2910164 showed no significant difference between patients and normal subjects
or between patients with and without clinical variables. Although patients carrying CC genotype of rs3746444 were found to
be more likely to develop hallucination and individuals carrying C allele to lack motivation, there is lacking association
between SCZ and the two SNPs at miRNAs, which may regulate immune response. 相似文献

The aim of this study was to perform an association study between two single nucleotide polymorphisms (SNPs) rs2910164 G>C and rs3746444 T>C in pre-miRNA (hsa-mir-146a and hsa-mir-499) and rheumatoid arthritis (RA) in the Han Chinese population. 208 Han Chinese patients with RA and 240 healthy controls were recruited in this study. The SNPs was genotyped by polymerase chain reaction-restriction fragment length polymorphism. Anti-cyclic citrullinated peptide (anti-CCP) antibody was measured by enzyme linked immunosorbent assay and rheumatoid factor (RF) was measured by rate nephelometry. The genotype frequencies between cases and controls were compared by χ(2) analysis. No significant association between the SNPs (rs2910164 and rs3746444) and RA was observed (P = 0.631 and 0.775, respectively), and the SNPs did not show any association with the RF-positive (P = 0.631 and 0.775, respectively). However, there was a significant difference on the level of anti-CCP antibody between different genotypes in rs3746444 (P = 0.007). The heterozygote CT had significantly higher level of anti-CCP antibody compared with homozygote CC and TT (P = 0.054 and 0.003, respectively). We first investigated the association between the SNPs (rs2910164 G>C and rs3746444 T>C) in the pre-miRNA (hsa-mir-146a and hsa-mir-499) and RA in a Han Chinese population. We did not find a significant association between the SNPs and the susceptibility to RA, while the SNP rs3746444 may affect anti-CCP antibody production. 相似文献

ObjectiveTo analyze the relationship of genetic polymorphisms in IL1β, IL6, TNF-α genes and their receptors genes with rheumatoid arthritis (RA) for northwest Han Chinese. This study also explores whether there are gene–gene interactions among these genetic polymorphisms.MethodsA total of 452 patients with RA and 373 matched healthy controls were enrolled to carry out a case-control study for 16 SNPs of IL1B-511 C > T, IL1B-31 T > C, IL1B+3954 C > T, IL1RN T > C, IL6-597 G > A, IL6-572 G > C, IL6-174 G > C, IL6R-183 G > A, IL6R exon2 T > A, IL6R exon1 A > C, TNFA-863 C > A, TNFA-857 C > T, TNFA-308 G > A, TNFA-238 G > A, TNFR1-383 A > C and TNFR2 T676G T > G from seven genes. Genotyping for the SNPs was conducted on the RotorGene 6000 PCR platform using in-house high resolution melting (HRM) approaches. Detection correctness was validated through direct sequencing. Generalized multifactor dimensionality reduction (GMDR) analysis was applied to discover likely gene–gene interaction model among the SNPs.ResultsThe results showed that the genotype distributions of TNFA-308, TNFA-857 and TNFA-863 are significantly different between case and control groups (P = 0.016, P = 0.048 and P = 0.016, respectively). Carriers of TNFA-857 mutant allele conferred risk to RA (OR = 1.525, 95% CI = 1.157–2.009) while those of TNFA-308 and TNFA-863 mutant alleles conferred protection to RA (OR = 0.459, 95% CI = 0.286–0.739; OR = 0.490, 95% CI = 0.329–0.732). GMDR analysis for the SNPs indicated that gene–gene interaction existed among IL1B-31, IL1RN, IL6-572, IL6R-183, IL6R-exon1 and TNFA-857. Thirteen of all genotypes of the six SNPs combination were discovered to have significant distribution difference between RA group and the control.ConclusionsThis study demonstrated that PCR-HRM assay is a highly efficient SNP genotyping method especially for the detection of large-scale samples. The SNPs of TNFA-308 and TNFA-863 are closely associated with RA susceptibility and that gene–gene interactions may occur among the six SNPs of IL1B-31, IL1RN, IL6-572, IL6R-183, IL6R-exon1 and TNFA-857 in RA patients from northwest Chinese Han population, especially these SNPs’ combination genotypes CT/TT/CC/GG/AC/CC, CT/TT/GC/AA/AC/CT and CT/CT/CC/GA/AC/CC to show high risk of RA susceptibility in our study. 相似文献

IntroductionSystemic lupus erythematosus (SLE) is a multisystem autoimmune disease. Currently, numerous genetic loci of SLE have been confirmed. Here we try to further explore additional genes contributing to SLE susceptibility in this study.MethodsForty nine single nucleotide polymorphisms (SNPs) with moderate-risk for SLE in previous study were genotyped in a large-scale replication study with a total of 3,522 cases and 8,252 controls using the Sequenom Massarray system. Association analyses were performed using logistic regression with gender or sample cohorts as a covariate through PLINK 1.07 software.ResultsThis replication effort confirmed five reported SLE susceptibility loci reaching genome-wide levels of significance (Pmeta <5.00 × 10−08): TNFSF4 (rs1418190, odds ratio (OR) = 0.81, Pmeta = 1.08 × 10−08; rs4916219, OR = 0.80, Pmeta = 7.77 × 10−09), IRF8 (rs2934498, OR = 1.25, Pmeta = 4.97 × 10−09), miR-146a (rs2431697, OR = 0.69, Pmeta = 1.15 × 10−22), CD44 (rs2732547, OR = 0.82, Pmeta = 1.55 × 10−11), and TMEM39A (rs12494314, OR = 0.84, Pmeta = 1.01 × 10−09). Further logistic regression analysis indicated that the genetic effects within TNFSF4 detected in this study are independent from our previously reported signals.ConclusionsThis study increases the number of established susceptibility loci for SLE in Han Chinese population and highlights the contribution of multiple variants of modest effect. Although further studies will be required to identify the causal alleles within these loci, the findings make a significant step forward in our understanding of the genetic contribution to SLE in Chinese population.

Although growing numbers of single nucleotide polymorphisms (SNPs) and microsatellites (short tandem repeat polymorphisms or STRPs) are used to infer population structure, their relative properties in this context remain poorly understood. SNPs and STRPs mutate differently, suggesting multi-locus genotypes at these loci might differ in ability to detect population structure. Here, we use coalescent simulations to measure the power of sets of SNPs and STRPs to identify population structure. To maximize the applicability of our results to empirical studies, we focus on the popular STRUCTURE analysis and evaluate the role of several biological and practical factors in the detection of population structure. We find that: (1) fewer unlinked STRPs than SNPs are needed to detect structure at recent divergence times <0.3 Ne generations; (2) accurate estimation of the number of populations requires many fewer STRPs than SNPs; (3) for both marker types, declines in power due to modest gene flow (Nem=1.0) are largely negated by increasing marker number; (4) variation in the STRP mutational model affects power modestly; (5) SNP haplotypes (θ=1, no recombination) provide power comparable with STRP loci (θ=10); (6) ascertainment schemes that select highly variable STRP or SNP loci increase power to detect structure, though ascertained data may not be suitable to other inference; and (7) when samples are drawn from an admixed population and one of its parent populations, the reduction in power to detect two populations is greater for STRPs than SNPs. These results should assist the design of multi-locus studies to detect population structure in nature. 相似文献

We found that cluster determinant 36 (CD36) gene is up-regulated in essential hypertension (EH) patients in our former research, but the association between CD36 gene variations and EH has not yet been clearly demonstrated. The relationship between CD36 gene single nucleotide polymorphisms (SNPs) and EH in the northeastern Han Chinese was examined in the present study through direct sequencing and genotype-detection. A total of 589 unrelated northeastern Han Chinese including 276 with EH and 313 controls were studied. SNPs in exon 7, exon 13 and intron 4 were detected using PCR-sequencing. The genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) or polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP). + 216T/C, + 273A/G, + 132C/T, + 217T/C, + 212T/G and + 233T/C polymorphisms were identified. Distributions of genotypes AA, GA and GG of + 273A/G polymorphism were significantly different between EH group and the control group (χ2: 9.056, p = 0.011) and G allelic frequency was higher in EH (p = 0.006, OR = 1.629, 95% CI [1.224–2.168]). Logistic regression analysis showed that + 273A/G polymorphism was closely associated with blood pressure (BP) after adjusting for ages. When subclassified by sex, the genotype distribution of + 273A/G (p = 0.011) and allelic frequency of G allele (p = 0.006) were significantly different between EH participants and controls in males, but not in females. Subgroup analysis performed by body mass index (BMI) suggested that the genotype distribution of + 273A/G and allelic frequency were significantly different in non-obese group and non-obese men, but the associations were not significant (non-obese group: p = 0.016, OR = 1.664, 95% CI [1.459–2.409]; non-obese men: p = 0.073, OR = 1.898, 95% CI [1.033–3.487]). + 273A/G polymorphism in CD36 gene was associated with EH, and + 273G could be an independent predictor. 相似文献

Background
To investigate whether the candidate genes that confer susceptibility to type 2 diabetes mellitus are also correlated with gestational diabetes mellitus (GDM) in pregnant Chinese women.Methodology/Principal Findings
In this study, 1764 unrelated pregnant women were recruited, of which 725 women had GDM and 1039 served as controls. Six single nucleotide polymorphisms (rs7754840 in CDKAL1, rs391300 in SRR, rs2383208 in CDKN2A/2B, rs4402960 in IGF2BP2, rs10830963 in MTNR1B, rs4607517 in GCK) were genotyped using TaqMan allelic discrimination assays. The genotype and allele distributions of each SNP between the GDM cases and controls and the combined effects of alleles for the risk of developing GDM were analyzed. We found that the rs4402960, rs2383208 and rs391300 were statistically associated with GDM (OR = 1.207, 95%CI = 1.029–1.417, p = 0.021; OR = 1.242, 95%CI = 1.077–1.432, p = 0.003; OR = 1.202, 95%CI = 1.020–1.416, P = 0.028, respectively). In addition, the effect was greater under a recessive model in rs391300 (OR = 1.820, 95%CI = 1.226–2.701, p = 0.003). Meanwhile, the joint effect of these three loci indicated an additive effect of multiple alleles on the risk of developing GDM with an OR of 1.196 per allele (p = 1.08×10−4). We also found that the risk alleles of rs2383208 (b = −0.085, p = 0.003), rs4402960 (b = −0.057, p = 0.046) and rs10830963 (b = −0.096, p = 0.001) were associated with HOMA-B, while rs7754840 was associated with decrease in insulin AUC during a 100 g OGTT given at the time of GDM diagnosis (b = −0.080, p = 0.007).Conclusions/Significance
Several risk alleles of type 2 diabetes were associated with GDM in pregnant Chinese women. The effects of these SNPs on GDM might be through the impairment of beta cell function and these risk loci contributed additively to the disease. 相似文献8.

Single-nucleotide polymorphisms (SNPs) of ADIPOQ, ADIPOR1, and ADIPOR2 have been associated with type 2 diabetes mellitus (T2DM), but there are many conflicting results especially in Chinese populations. To investigate the contribution of the adiponectin genes and their receptors to T2DM, a case-control study was performed and 11 SNPs ofADIPOQ, ADIPOR1, and ADIPOR2 were genotyped in 985 T2DM and 1,050 control subjects, rs 16861194 (-11426 A〉G) in the putative promoter of ADIPOQ was associated with T2DM (P = 0.007; OR = 1.29, 95% CI 1.08-1.55). None of the other 10 SNPs were associated with T2DM in this study, although rs2241766 and rs1501299 were reported to be associated with T2DM in previous Chinese studies. There was also no significant difference found from the ADIPOQ haplotype analysis, which contains rs 16861194. In addition, we also assessed potential gene-gene interactions in three genes and no interactions were found. In conclusion, our results supported the ADIPOQ gene as a possible risk factor for type 2 diabetes in Han Chinese population. 相似文献

Single-nucleotide polymorphisms (SNPs) in pre-miRNAs may alter microRNA (miRNA) expression levels or processing and contribute to susceptibility to a wide range of diseases. We investigated the correlation between four SNPs (rs11614913, rs3746444, rs2910164, and rs229283) in pre-miRNAs and the risk of asthma in 220 asthma patients and 540 controls using polymerase chain reaction-restriction fragment length polymorphism methodology and DNA-sequencing. There were significant differences in the genotype and allelic distribution of rs2910164G/C and rs2292832C/T polymorphisms among cases and controls. The CC genotype and C allele of rs2910164G/C were significantly associated with a decreased risk of asthma (CC vs. GG, odds ratio [OR]?= 0.51, 95% confidence interval [CI]: 0.31-0.82; C vs. G, OR = 0.74, 95% CI: 0.59-0.93). Similarly, the TT genotype and T allele of rs2292832C/T were significantly associated with a decreased risk of asthma (TT vs. CC, OR = 0.56, 95% CI: 0.33-0.95; T vs. C, OR = 0.71, 95% CI: 0.53-0.95). However, no significant association between the other two polymorphisms (i.e., rs11614913C/T and rs3746444C/T) and the risk of asthma was observed. Our data indicate that rs2910164G/C and rs2292832C/T may play a role in the development of asthma. 相似文献

Allergic Rhinitis (AR) and allergic asthma (AS) are very common diseases involving genetic and environmental factors. Most
patients with asthma also have rhinitis, which suggests the concept of ‘one airway, one disease’. A disintegrin and metalloproteinase
33 (ADAM33) was discovered as the first asthma-susceptible gene by positional cloning. To evaluate the potential influences
of ADAM33 gene polymorphisms on concomitant allergic rhinitis and asthma (ARA), a case-control study was conducted in Han
population of Northeast China. Six polymorphic sites (V4, T + 1, T2, T1, S1 and Q − 1) were genotyped in 135 ARA patients
and 151 controls (CTR). Genotypes were determined by the polymerase chain restriction fragment length polymorphism (PCR-RFLP)
method. Data was analyzed using the Chisquaretest and Haploview software. The SNPs (V4 G/C, T2 A/G, T1 G/A, and Q − 1A/G)
of the ADAM33 gene may be the causal variants in ARA disease.

This study investigated the genetic association of three single nucleotide polymorphisms(SNPs; rs10483727, rs33912345, and rs146737847) at the SIX1-SIX6 locus with primary open angle glaucoma(POAG) in the Chinese population. A total of 866 subjects with POAG(685 high-tension glaucoma(HTG) and 181 normal-tension glaucoma(NTG)) and 266 control individuals were included. Significant genetic association was identified for rs10483727 in HTG(P=0.02; odds ratio(OR)=1.31), NTG(P=7.41×10~(-6); OR=2.71), and POAG(i.e., HTG and NTG combined; P=0.001; OR=1.44). rs33912345 was also significantly associated with HTG(P=0.008; OR=1.36), NTG(P=2.72×10~(-6); OR=2.27), and POAG(P=3.84×10~(-4); OR=1.49). The rare SIX6 mutation, rs146737847, was not found in the subjects enrolled in this study. Stratification by patient age identified that both rs10483727 and rs33912345 were significantly associated with NTG in patients aged above 40 years(P=2.08×10~(-5); OR=2.28), whereas in patients aged between 20–40 years, rs33912345 was significantly associated with NTG(P=0.017; OR=2.06). In HTG, the genetic associations for both rs10483727 and rs33912345 were significant in patients aged between 20–40 years(P=0.006; OR=1.56) but not in those aged above 40 years(P=0.118, OR=1.21 and P=0.042, OR=1.29, respectively). This study replicated the association of POAG with two SNPs at the SIX1-SIX6 locus and demonstrated that SNPs, rs10483727 and rs33912345, are significantly associated with POAG, especially with NTG in patients aged above 40 years. 相似文献

Our previous studies showed elevated tumor necrosis factor-like ligand 1 aberrance (TL1A) expression in systemic lupus erythematosus (SLE). However, TL1A polymorphisms with SLE susceptibility remain to be elucidated. In addition, we made meta-analysis to evaluate the relationship of TL1A polymorphisms and autoimmune diseases owing to inconsistent results. The present research was carried out by 404 SLE, 150 primary Sjogren's syndrome (pSS) patients, and 574 healthy individuals. Three TL1A polymorphisms (rs3810936, rs6478109, rs7848647) were genotyped using TaqMan genotyping assay. Then, the meta-analysis was performed by collecting the present case-control study and previously published research. Results showed that genotypes of rs3810936, rs7848647 were different between SLE patients and healthy controls, whereas no significant association was observed in the three polymorphisms and pSS patients. Genotypes distribution of rs6478109, rs7848647 were strongly related to lupus nephritis within SLE (p = 0.004, p = 0.011), respectively. Moreover, combined meta-analysis consisted of ten comparative research involving 4,305 patients and 5,600 controls. An association between autoimmune diseases and rs6478109 polymorphism was found. Our findings indicate that gene polymorphisms (rs3810936, rs7848647) of TL1A might correlate with lupus. 相似文献

Interleukin-18 (IL-18) is a multi-functional cytokine capable of inducing either Th1 or Th2 polarization depending on the immunologic milieu. IL-18 may influence the host response to Mycobacterium tuberculosis (M.tb) infection. To investigate the relationship between single nucleotide polymorphisms of the IL-18 and susceptibility to pulmonary tuberculosis in the Chinese Han population, the IL-18 gene was sequenced to detect polymorphisms and to examine the genotype frequencies in 300 patients and 702 healthy controls. DNA sequencing revealed three IL-18 variants: rs1946518, rs5744247, and rs549908. It also revealed that allele A of rs1946518 confers a 1.47-fold increased risk of developing tuberculosis (TB) (P = 0.0001, OR [95%CI] = 1.47 [1.21-1.78]), and that the C allele of rs5744247 confers a 0.77-fold decreased risk of disease (P = 0.01, R [95%CI] = 0.77 [0.632-0.937]). The genotypes rs1946518, rs5744247 and rs549908 were found to be significantly associated with TB. Estimation of the frequencies of haplotypes revealed a potential risk haplotype AGA (P = 0.01, OR [95%CI] = 1.41 [1.15-1.72]) and a protective haplotype CCA (P = 0.01, OR [95%CI] = 0.70 [0.57-0.85]) for TB. The present findings suggest that polymorphisms in the IL-18 gene may affect susceptibility to TB and increase the risk of developing the disease in the Chinese Han population. 相似文献

Several genome-wide association studies (GWASs) have reported associations between single nucleotide polymorphisms (SNPs) and uric acid concentrations or gout in a number of different ethnic populations. To clarify the global relevance of the previously identified SNPs in the development of the qualitative trait gout, in the present study, the associations between two SNPs in the glucokinase (hexokinase 4) regulator (GCKR) gene and gout were assessed in a male Chinese Han population. The study population comprised 476 male gout patients and 465 male controls. Multiple PCR was performed using time-of-flight mass spectrometry (MALDI-TOF MS) to identify genotypes. Two SNPs, rs780093 and rs780094, located in intronic regions of the GCKR gene were found to be significantly associated with the development of gout. Thus, the association between the two GCKR SNPs and gout was replicated in the male Han Chinese population investigated in the present study. Furthermore, GCKR was identified as a novel candidate gene associated with gout. 相似文献
