Aggregated Somatic Mutation

Description

Aggregated Somatic Mutation is a file type that reports somatic mutations for all of the cases in a project and includes information associated with each mutation.

Overview

Aggregated Somatic Mutation files are generated by aggregating all of the case-level annotated VCFs (each from a single case) associated with a project and variant-calling pipeline¹. The GDC used a modified version of the vcf2maf script to generate aggregated somatic mutation files^2,3.

Data Formats

Aggregated Somatic Mutation files are available in MAF format. MAF files are tab-delimited and associate each mutation with biologically relevant data. See the GDC MAF File Format documentation for a detailed description of this file type⁴. Aggregated Somatic Mutation files can be downloaded from the GDC Data Portal⁵.
