概括

亚马逊土著居民的遗传变异可能会影响2019年新冠病毒病 (COVID-19) 严重程度. 研究人员在关键基因中发现了新的变异,提供了对影响SARS-CoV-2感染结果的人口特异性遗传因素的见解.

科学领域:

遗传学是一个遗传学.
基因组学就是基因组学.
传染性疾病传染性疾病

背景情况:

全基因组关联研究 (GWAS) 表明遗传因素影响COVID-19的严重程度.
大多数GWAS专注于欧洲人口,限制了对土著群体遗传变异性的理解.
巴西亚马逊地区的土著人口可能具有独特的遗传因素,影响SARS-CoV-2感染.

研究的目的:

为了调查与COVID-19严重程度相关的七个选定基因 (AQP3,ARHGAP27,ELF5L,IFNAR2,LIMD1,OAS1,UPK1A) 的遗传变异.
识别和描述这些基因中的已知和潜在的新型变体,来自巴西亚马逊的土著人民.
为了比较这个群体中的等位基因频率与其他大陆群体.

主要方法:

来自巴西亚马逊地区的64名健康土著个体的整个外基因组测序.
在目标基因中的遗传变异的识别和表征.
与全球人口数据对等基因频率的比较分析.

主要成果:

在七个研究的基因中,共发现了66种变异.
在ARHGAP27基因中检测到一种高影响变异 (rs201721078).
在亚马逊土著人口中,在AQP3,IFNAR2和LIMD1基因中发现了三种新型变异,影响程度不同 (低,中等,修饰).

结论:

这项研究强调了亚马逊土著人口中与COVID-19相关的独特遗传变异的存在.
已识别的变种,包括新型变种,有助于了解对SARS-CoV-2感染的特定种群遗传影响.
需要进一步的研究来阐明这些变体对COVID-19易感性和严重性的功能影响.

关键词:

在 COVID-19 疫情中,这就是SARS-CoV-2病毒.在SNP中,SNP是SNP.冠状病毒冠状病毒的新冠病毒.土著居民是土著居民.

Comparing Copy Number Variations and SNPs

Comparing Copy Number Variations and SNPs

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
