概括

IFITM3基因rs12252 G等位基因和AG/GG基因型与埃及人的COVID-19感染易感性增加有关. 患者的血清IFNL3水平也较高,但这两个因素都不能预测疾病的严重程度或死亡率.

科学领域:

遗传学和免疫学遗传学和免疫学
传染性疾病传染性疾病
分子生物学分子生物学

背景情况:

个人对COVID-19的敏感性可能涉及遗传因素.
干扰素诱导的跨膜3 (IFITM3) 和干扰素兰巴达3 (IFNL3) 在抗病毒防御中起作用.
调查与COVID-19相关的IFITM3基因多态和IFNL3血清水平至关重要.

研究的目的:

为了检查IFITM3基因多态性 (rs12252) 与COVID-19的关联.
评估血清IFNL3水平与COVID-19感染,严重程度和死亡率之间的关系.
为了确定这些因素是否预测埃及人口中的COVID-19结果.

主要方法:

一项涉及埃及154名COVID-19患者和100名健康对照者的病例控制研究.
使用TaqMan实时PCR进行IFITM3 rs12252多态的基因定型.
通过ELISA量化血清IFNL3水平.

主要成果:

在COVID-19患者中,IFITM3 rs12252的G等位基因和AG/GG基因型明显更频繁.
在IFITM3 rs12252变体和COVID-19严重程度或结果之间没有发现显著的关联.
血清IFNL3水平在患者中升高,但在轻度和重度病例之间没有显著差异,也没有与结果相关.

结论:

IFITM3 rs12252 AG基因型和G等位基因与埃及人的COVID-19易感性有关,而不是严重程度或结果.
血清IFNL3水平升高与COVID-19易感性相关,但与严重程度无关.
这两个因素都是感染的独立预测因素,但不是严重的疾病进展.

关键词:

根据COVID-19的情况,如果FITM3是IFITM3,那么它是什么?在IFN-λ3中.基因型定制是基因型定制.多形态主义的多态主义.

Single Nucleotide Polymorphisms-SNPs

Single Nucleotide Polymorphisms-SNPs

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,...
