We’re moving the GATK website, docs and forum to a new platform. Read the full story and breakdown of key changes on this blog.
If you happen to see a question you know the answer to, please do chime in and help your fellow community members. We encourage our fourm members to be more involved, jump in and help out your fellow researchers with their questions. GATK forum is a community forum and helping each other with using GATK tools and research is the cornerstone of our success as a genomics research community.We appreciate your help!
Test-drive the GATK tools and Best Practices pipelines on Terra
Check out this blog post to learn how you can get started with GATK and try out the pipelines in preconfigured workspaces (with a user-friendly interface!) without having to install anything.
What is MuTect?
Please note that this article refers to the original standalone version of MuTect. A new version is now available within GATK (starting at GATK 3.5) under the name MuTect2. This new version is able to call both SNPs and indels. See the GATK version 3.5 release notes and the MuTect2 tool documentation for further details.
MuTect is a tool developed at the Broad Institute for the reliable and accurate identification of somatic point mutations in next generation sequencing data of cancer genomes. It is built on top of the GenomeAnalysisToolkit (GATK), which is also developed at the Broad Institute, so it uses the same command-line conventions and (almost all) the same input and output file formats.
MuTect operates on sequencing data for matched normal and tumor tissue samples, and it outputs mutation calls as well as optional coverage results.
In a nutshell, the analysis itself consists of three steps:
- Pre-processing the aligned reads in the tumor and normal sequencing data
- Statistical analysis to identify sites that are likely to carry somatic mutations with high confidence
- Post-processing of candidate somatic mutations
For complete details, please see the method documentation as well as our 2013 publication in Nature Biotechnology:
