概括
CD209 rs4804803 G等位基因与埃及人的风湿性关节炎 (RA) 易感性增加有关. 这种遗传因素也与更严重的RA症状相关,如早晨硬和CRP水平升高.
科学领域:
- 遗传学 是一个遗传学.
- 免疫学 免疫学 免疫学
- 类风湿病学 类风湿病学
背景情况:
- 类风湿性关节炎 (RA) 有遗传成分,但CD209基因多态的作用尚不清楚.
- 调查CD209单核酸多态 (SNP) 可能会澄清RA易感性.
研究的目的:
- 为了检查CD209SNP (rs4804803和rs735239) 与埃及人口中的类风湿性关节炎 (RA) 风险之间的关联.
- 为了确定特定的CD209基因型是否影响RA易感性和临床表现.
主要方法:
- 进行了一项病例控制研究,涉及108名参与者 (54名RA患者和54名对照).
- 用多重PCR和dARMS进行了CD209促销者SNPs rs4804803和rs735239的基因型鉴定.
- 根据2010年ACR/EULAR分类标准,对RA进行诊断.
主要成果:
- CD209 rs4804803 SNP,特别是AG和GG基因型,与对照组相比,RA患者的频率显著更高 (P=0.036和P=0.006,分别).
- rs4804803 G等位基因增加了RA风险 (P=0.001),观察到AG+GG基因型 (P=0.003) 和GG多态 (P=0.017) 的风险增加.
- 对于rs735239.没有发现显著的关联. 具有rs4804803 AG/GG基因型的RA患者报告了更多的早晨硬 (P=0.001) 和更高的CRP水平 (P=0.009).
结论:
- CD209 rs4804803的多态性,特别是G等位基因,与埃及人的风湿性关节炎易感性增加有显著的关联.
- 这种遗传变异也可能导致RA更严重的临床特征,包括早晨硬和C-反应性蛋白水平升高.

Genome-wide Association Studies-GWAS
15.2K
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.

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
439
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Single Nucleotide Polymorphisms-SNPs
17.8K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

The JAK-STAT Signaling Pathway
11.8K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
