背景情况:

短读测序变异调用基准仅限于有信心的区域,在未经测试的人类样本中可能产生10倍的错误率.
现有的变量调用"容易区域"集往往是有偏见的,或者不考虑非参考样本.

研究的目的:

为了获得准确的短读变异,在不同的人类基因组中导出样本无关的简单区域.
提供可靠的资源来过人类样本中的虚假变异呼叫.

主要方法:

使用了数百个高质量的人类基因组组合来定义新的易用区域.
被保证的地区是独立于样本的,并且在覆盖范围和变种呼叫的便利性方面是平衡的.

主要成果:

已开发的样本无关容易区域占GRCh38的88.2%和编码区域的92.2%.
这些区域准确识别了ClinVar中的96.3%的致病变体.
该方法适用于其他具有多个基因组组合的人类组合和物种.

结论:

这种资源为过不准确的变种呼叫提供了强大而方便的方法.
在临床和研究应用中提高变异调用准确度.

Next-generation Sequencing

Next-generation Sequencing

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

Although all next-generation methods use different technologies, they all share a set of standard features....

RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Genome Annotation and Assembly

Genome Annotation and Assembly

The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
