概括

确定一个变异性等位基因频率 (VAF) 值有助于过医学外基因组测序中的技术文物. 低于0.30的VAF可以将治愈时间缩短20%,同时保留临床上显著的变异.

科学领域:

基因组学就是基因组学.
生物信息学是一种生物信息学.
临床诊断临床诊断临床诊断

背景情况:

医疗外因组测序管道需要对临床解释进行变异优先级.
变异基因频率 (VAF) 是用于识别技术工件的指标.
目前还没有标准化的VAF值来过exome测序中的文物.

研究的目的:

评估VAF在临床外基因组测序中区分技术工件和真实变体中的实用性.
提出一个最佳的VAF过门,以提高变种选的效率.

主要方法:

分析了来自289名患者的13,122个手工精选的变体,这些变体使用Agilent SureSelect专注的Exome进行了测序.
对临床报告的单核酸多态 (SNP) 和技术工件的VAF分布的评估.
评估VAF<0.30波器对手动固化时间和变异捕获的影响.

主要成果:

临床报告的变种具有VAF在0.33和0.63.3之间.
82%的确定的技术工件的VAF低于0.33.
拟议的VAF值约为0.30,有效地将文物从真实变体中分离出来.

结论:

实施大约0.30的VAF值可以显著减少外基因组测序中的手动修复工作量.
这种过策略有效地消除了技术工件,同时保留了医学上相关的变体.
优化VAF值可以提高临床基因组学工作流程的效率和准确性.

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%...
