Polymorphisms of STAT4 and the risk of inflammatory bowel disease: A case-control study in Chinese Han population.

ABSTRACT: Signal transducer and activator of transcription 4 (STAT4) is a transcription factor involved in the signaling pathways of several cytokines, playing an essential role in the development of inflammation in various immune-mediated diseases. Genetic association studies have shown that the STAT4 gene was significantly associated with inflammatory bowel disease (IBD) in Spanish and Caucasian populations. However, these associations in other ethnic populations remain unknown. In the present study, we evaluated the role of the STAT4 rs7574865 and rs7582694 polymorphisms on IBD in 562 unrelated Chinese Han subjects by assessing distributions of genotypes and allele frequencies. Results showed that neither rs7574865 [Crohn's disease (CD): P=0.66, odds ratio (OR) = 0.95, 95% confidence interval (CI) 0.74-1.21; ulcerative colitis (UC): P=0.43, OR=0.85, 95% CI 0.56-1.28; IBD: P=0.52, OR=0.93, 95% CI 0.73-1.17] nor rs7582694 (CD: P=0.40, OR=1.12, 95% CI 0.86-1.44; UC: P=0.50, OR=0.86, 95% CI 0.56-1.33; IBD: P=0.62, OR=1.06, 95% CI 0.83-1.36) was significantly associated with IBD, although the genotype frequency of rs7574865 varied in patients and the controls. In conclusion, our data did not support that STAT4 variants contribute to IBD susceptibility in the Chinese Han population.

Project description:BackgroundLumbar disc herniation (LDH) is a complex spinal disease, with multiple genetic polymorphisms being related to its risk. Nevertheless, the role of LINC-PINT polymorphisms in LDH risk has remained unknown. Therefore, this study aimed to investigate the association between LINC-PINT polymorphisms and LDH risk.MethodsDNA was extracted from 504 LDH patients and 500 healthy controls. Three single nucleotide polymorphisms (SNPs) in LINC-PINT were selected and genotyped using Agena MassARRAY. We used logistic regression analysis to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs) under multiple genetic models to evaluate the association between LINC-PINT polymorphisms and LDH risk. Haploview 4.2 and SNPStats software were used to evaluate the linkage strength of SNPs and the correlation between haplotypes and LDH risk. The impact of SNP-SNP interactions on LDH risk was analyzed using multi-factor dimensionality reduction (MDR).ResultsResults showed that rs157916 (G vs. A: OR = 1.23, FDR-p = 0.029) and rs7801029 (G vs. C: OR = 1.39, FDR-p = 0.006; GG vs. CC: OR = 2.34, FDR-p = 0.038; recessive: OR = 2.13, FDR-p = 0.045; additive: OR = 1.39, FDR-p = 0.030) were associated with an increased risk of LDH. Furthermore, LINC-PINT rs157916 and rs780129 were found to be significantly associated with LDH risk in males. The "GGG" haplotype was associated with increased LDH risk (OR = 1.41, FDR-p = 0.006). MDR analysis indicated that the interaction between rs7801029 and rs16873842 was associated with an increased risk of LDH (OR = 1.47, p = 0.004). Additionally, there were significant differences in C-reactive protein levels among different genotypes of rs157916 and rs780129 (p < 0.05).ConclusionThis study suggests that LINC-PINT gene polymorphisms (rs157916 and rs7801029) are considered risk factors for LDH in the Chinese Han population and provide a scientific basis for early screening, prevention, and diagnosis of LDH.
