The MAF - Mutation Annotation Format File is a text file format that is used in capturing mutations is cells. This is file format that is maintained by the National Cancer Institute in conjunction with the NHGR (National Genome Research Institute) via a research project under the moniker The Cancer Genome Atlas. The MAF - Mutation Annotation Format File has the capability to capture and save genome and cell data utilizing tab delimited text. This file format is used in cancer research for the purpose of capturing single nucleotide polymorphisms.
This file is used primarily by applications that are custom designed for specific types of cancer research and is capable of providing analytic data that is highly relevant to the research being conducted. Although this file is normally used with custom software, it can be accessed and viewed through the common text editor. Over last few years this file has undergone a number of revisions
