Next-generation sequencing (NGS) has become a powerful and efficient tool for routine mutation screening in clinical research. As each NGS test yields hundreds of variants, the current challenge is to meaningfully interpret the data and select potential candidates. Analyzing each variant while manually investigating several relevant databases to collect specific information is a cumbersome and time-consuming process, and it requires expertise and familiarity with these databases. Thus, a tool that can seamlessly annotate variants with clinically relevant databases under one common interface would be of great help for variant annotation, cross-referencing, and visualization. This tool would allow variants to be processed in an automated and high-throughput manner and facilitate the investigation of variants in several genome browsers. Several analysis tools are available for raw sequencing-read processing and variant identification, but an automated variant filtering, annotation, cross-referencing, and visualization tool is still lacking. To fulfill these requirements, we developed DaMold, a Web-based, user-friendly tool that can filter and annotate variants and can access and compile information from 37 resources. It is easy to use, provides flexible input options, and accepts variants from NGS and Sanger sequencing as well as hotspots in VCF and BED formats. DaMold is available as an online application at http://damold.platomics.com/index.html, and as a Docker container and virtual machine at https://sourceforge.net/projects/damold/.
下一代测序(NGS)已成为临床研究中进行常规突变筛查的强大而高效的工具。由于每次NGS检测都会产生数百个变异,当前的挑战是有意义地解释数据并选择潜在的候选变异。在手动调查几个相关数据库以收集特定信息的同时分析每个变异是一个繁琐且耗时的过程,并且需要对这些数据库有专业知识和熟悉程度。因此,一个能够在一个通用界面下用临床相关数据库无缝注释变异的工具,对于变异注释、交叉引用和可视化将有很大帮助。该工具将允许以自动化和高通量的方式处理变异,并便于在多个基因组浏览器中研究变异。有几种分析工具可用于原始测序读数处理和变异识别,但仍缺乏一个自动化的变异过滤、注释、交叉引用和可视化工具。为了满足这些要求,我们开发了DaMold,这是一个基于网络的、用户友好的工具,它可以过滤和注释变异,并可以从37个资源中访问和编译信息。它易于使用,提供灵活的输入选项,并接受来自NGS和桑格测序的变异以及VCF和BED格式的热点区域。DaMold可作为在线应用程序在http://damold.platomics.com/index.html上获取,也可作为Docker容器和虚拟机在https://sourceforge.net/projects/damold/上获取。
