A large number of genetic polymorphisms in immune-related genes have been extensively examined for their roles in the susceptibility of gastric cancer (GC) and colorectal cancer (CRC), including <i>IL4</i> gene rs2070874, <i>IL4RA</i> gene rs1801275, <i>IL18</i> gene rs187238, <i>IL18RAP</i> gene rs917997, <i>IL17A</i> gene rs8193036, <i>IL23R</i> gene rs1884444 and <i>IL23R</i> gene rs10889677. However, there is no consistent conclusion, which calls for further research. In this case–control study, these 7 genetic polymorphisms were genotyped by Sanger sequencing in a total of 1247 patients with cancer (GC/CRC: 460/787) and 800 healthy individuals. A total of 31 previous studies and our present study were included in this meta-analysis. The case–control study revealed that in Hubei Chinese population, rs2070874, rs187238 and rs10889677 were significantly associated with CRC risk, whereas only rs917997 was significantly associated with GC risk.

We aimed to study the prevalence of C4A and C4B null alleles in a cohort of SLE patients with persistently low C4 levels compared to healthy controls (HC). Patients with SLE and HC were recruited for this prospective observational study. C4 (C4AQ and C4BQ) polymorphisms were tested using a touch-down polymerase chain reaction protocol. One hundred and three SLE patients and 103 HC were included in the study. Persistently low C4 levels were observed in 25 (23.6%) of SLE. The frequency of C4A and C4B null alleles was similarly distributed across SLE and HC (4% and 3.8%, respectively). Univariate analysis showed a low age, higher proportion of elevated dsDNA, and higher positive anti-SSA (Sjogren's syndrome-related antigen A) antibodies at presentation were associated in SLE patients with the null allele group on comparison without the null allele group. However, these associations did not persist in the multivariate analysis. In conclusion, C4 null allele frequency was similar in SLE and HC.

{"title":"Association between a single-nucleotide polymorphism of the angiotensin-converting enzyme gene and susceptibility to systemic lupus erythematosus in the Hainanese population of China","authors":"Qi Zhang,&nbsp;Yanping Zhuang,&nbsp;Xuan Zhang,&nbsp;Guiling Lin,&nbsp;Huitao Wu,&nbsp;Ziman He,&nbsp;Zhe Wang,&nbsp;Wenlu Xu,&nbsp;Xiyu Yin,&nbsp;Linglan Su,&nbsp;Xiaokang Jia,&nbsp;Aimin Gong","doi":"10.1111/iji.12690","DOIUrl":"10.1111/iji.12690","url":null,"abstract":"<p>The angiotensin-converting enzyme (ACE) gene plays a significant role in regulating immune responses and inflammatory processes, thus impacting the susceptibility to systemic lupus erythematosus (SLE). Understanding how single-nucleotide polymorphisms (SNPs) within the ACE gene contribute to the genetic susceptibility to SLE is essential for comprehending the disease's aetiology. Therefore, exploring this relationship in the Hainan region of China is crucial for gaining insights into the pathogenesis of SLE. This study comprised 428 participants, including 214 SLE patients and 214 healthy controls. Clinical data were gathered, and blood samples were collected. Genotyping of three SNPs (<i>rs4459609</i>, <i>rs4309</i>, <i>rs1987692</i>) within the ACE gene was performed using SNaPshot technology. The frequencies of alleles and genotypes of these three SNPs were compared between the SLE and control groups. Combining different genetic models and haplotype analysis, the correlation between ACE gene polymorphisms and SLE was investigated. Both study groups exhibited conformity with the Hardy–Weinberg genetic equilibrium (<i>p</i> &gt; .05). Significant differences were observed in the genotype frequency distributions of ACE genes <i>rs4459609</i>, <i>rs4309</i> and <i>rs1987692</i> between the SLE and control groups (<i>p</i> = .009, .008, .032, respectively). The frequency of allele T at <i>rs4309</i> was significantly higher in the SLE group than in the control group, correlating significantly with increased SLE risk (odds ratio [OR] = 1.527, 95% confidence interval [CI] = 1.147–2.035). Associations among ACE <i>rs4459609</i>, <i>rs4309</i> and <i>rs1987692</i> polymorphisms and increased susceptibility to SLE were found under co-dominant and dominant models (<i>p</i> &lt; .05, with OR values and 95% CI greater than 1). Linkage disequilibrium was observed among <i>rs4459609</i>, <i>rs4309</i> and <i>rs1987692</i>, and haplotype analysis revealed a significantly higher frequency of the CCA haplotype in the control group compared to the SLE group (<i>p</i> &lt; .001). The ACA and ATA haplotypes showed significantly higher frequencies in the SLE group than in the control group (<i>p</i> = .014, <i>p</i> = .013, respectively). ACE gene polymorphisms are associated with the genetic susceptibility to SLE. The AC and AA genotypes at the <i>rs4459609</i> locus, the TT genotype and T allele at the <i>rs4309</i> locus and the AC and CC genotypes at the <i>rs1987692</i> locus may serve as risk factors for the development of SLE.</p>","PeriodicalId":14003,"journal":{"name":"International Journal of Immunogenetics","volume":"51 5","pages":"319-329"},"PeriodicalIF":2.3,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/iji.12690","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141751654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
