概括
这次元分析发现,甲基基叶酸减少酶 (MTHFR) 基因多态体C677T和A1298C与心肌梗塞 (MI) 的风险增加有关. 这些发现突出了心血管疾病易感性的遗传成分.
科学领域:
- 遗传学和心血管疾病
- 分子流行病学分子流行病学
- 心血管风险的生物标志物
背景情况:
- 基因多态基因甲基酸缩酶 (MTHFR) 基因多态基因,特别是C677T和A1298C,正在研究它们在心血管健康中的作用.
- 了解MTHFR基因变异与心肌梗塞 (MI) 易感性之间的关联对于个性化风险评估至关重要.
研究的目的:
- 综合评估MTHFR基因多态 (C677T和A1298C) 与心肌梗塞 (MI) 风险之间的关联.
- 综合来自多项研究的证据,以确定这些MTHFR变异对MI易感性的整体影响.
主要方法:
- 在主要数据库 (MEDLINE,科学网,Scopus) 进行了系统的文献搜索,直到2023年4月.
- 分析包括66项针对C677T (16,860例,20,403对照) 的研究和18项针对A1298C (3162例,3632对照) 的研究.
- 用各种遗传模型 (主导性,衰退性,等位基因) 来评估这些关联.
主要成果:
- 在多个遗传模型 (例如,衰退:OR=1.20,P<0.001) 中,在MTHFR C677T多态和心脏病风险之间发现了显著的关联.
- MTHFR A1298C多态性在衰退和等位基模型 (例如,衰退:OR=1.27,P=0.008) 中显示出与MI风险的边际显著关联.
- 超回归分析表明,潜在因素对观察到的异质性没有显著的贡献.
结论:
- 这一元分析证实了MTHFR基因C677T和A1298C多态性之间存在关联,以及心肌梗塞风险增加.
- 这些遗传变异可能成为潜在的MI易感性生物标志物,需要在不同人群中进行进一步的研究.

Genome-wide Association Studies-GWAS
13.5K
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.

Translation

Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
