Genome-wide Association Studies-GWAS

12.5K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

  • 免疫学 免疫学 免疫学
  • 整形外科 整形外科 整形外科

背景情况:

  • 冷的肩膀 (FS) 涉及关节囊加厚和纤维化,导致收缩和关节体积减少.
  • 这些FS病理变化的确切原因尚不清楚.

研究的目的:

  • 为了调查病原性基因在冷肩部的潜在参与.
  • 分析这些基因在FS疾病进展中的作用.
  • 确定与FS因果相关的关键基因.

主要方法:

  • 差异基因表达分析和权重基因共同表达网络分析 (WGCNA) 确定了共同表达的基因.
  • 门德尔随机化 (MR) 分析,使用表达定量特征位置 (eQTL) 和GWAS数据,确定了因果基因.
  • 通过RT-qPCR验证了关键基因;通过名图和ROC曲线评估了诊断价值;通过CIBERSORT分析了免疫细胞透.

主要成果:

  • 确定了295个重叠的共同表达的基因.
  • 四个基因 (ADAMTS1,NR4A2,PARD6G,SMKR1) 显示出与FS的积极因果关系,由RT-qPCR证实.
  • 一个名图模型和ROC曲线表明了诊断价值;ADAMTS1与FS.中的免疫细胞透有关.

结论:

  • 较高的ADAMTS1,NR4A2,PARD6G和SMKR1表达水平与冷肩风险的增加有关.
  • 这些发现表明对FS的遗传倾向.
  • 对这些基因功能的进一步研究可能会导致针对性FS治疗.
