概括

在AmpliSeq测试中的SNP条形码为疟疾寄生虫提供了与微卫星面板相似的种群遗传数据. 虽然这两种方法都有优缺点,但AmpliSeq测定更昂贵,并且在检测Plasmodium vivax中的多克隆感染方面效率较低.

科学领域:

遗传学是一个遗传学.
分子生物学分子生物学
寄生虫学的寄生虫学

背景情况:

疟疾分子监测 (MMS) 对于了解传播动态和指导控制计划至关重要.
之前,AmpliSeq测定中的SNP条形码已被开发用于MMS,评估药物耐药性和基因删除等特征.
这些测试还提供了对Plasmodium寄生虫的种群遗传学估计.

研究的目的:

为了比较AmpliSeq测试中的SNP条形码的遗传分辨率与传统的微卫星 (MS) 面板.
研究亚马逊疟疾寄生虫的种群遗传学,特别是Plasmodium vivax和Plasmodium falciparum的种群遗传学.
评估每种疟疾监测方法的成本效益和准确性.

主要方法:

分析了来自秘鲁亚马逊三个地区的51个P.vivax和80个P.falciparum样本.
使用SNP条形码 (P. vivax的40个SNP,P. falciparum的28个SNP) 和MS面板 (P. vivax的16个MS,P. falciparum的7个MS) 的种群遗传学估计和成本的比较.
评估寄生虫种群之间的遗传多样性 (He) 和遗传差异化 (FST).

主要成果:

无论是SNP条形码还是MS面板都显示了P. vivax和P. falciparum的遗传多样性 (He) 和差异化 (FST) 的趋势相似.
通过这两种方法观察到P. falciparum的类似种群结构聚类,但P. vivax.没有看到地理聚类.
与SNP条形码相比,微卫星面板检测到P.vivax中多克隆感染的比例明显更高 (69%对33%). AmpliSeq测试的每样本成本较高 (183美元与27-49美元对比).

结论:

在AmpliSeq测定中的SNP条形码提供了与P. vivax和P. falciparum的MS面板相比较的种群遗传洞察力.
在检测多克隆感染方面存在差异,特别是P. vivax,MS面板更敏感.
在SNP条形码和MS面板之间做出选择应该取决于具体的研究目标,成本考虑和可用的资源.

Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

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...

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%...
