The International Cancer Genome Consortium (ICGC) is a collaborative effort to 
characterize genomic abnormalities in 50 different cancer types. To make this 
data available, the ICGC has created the ICGC Data Portal. Powered by the 
BioMart software, the Data Portal allows each ICGC member institution to manage 
and maintain its own databases locally, while seamlessly presenting all the data 
in a single access point for users. The Data Portal currently contains data from 
24 cancer projects, including ICGC, The Cancer Genome Atlas (TCGA), Johns 
Hopkins University, and the Tumor Sequencing Project. It consists of 3478 
genomes and 13 cancer types and subtypes. Available open access data types 
include simple somatic mutations, copy number alterations, structural 
rearrangements, gene expression, microRNAs, DNA methylation and exon junctions. 
Additionally, simple germline variations are available as controlled access 
data. The Data Portal uses a web-based graphical user interface (GUI) to offer 
researchers multiple ways to quickly and easily search and analyze the available 
data. The web interface can assist in constructing complicated queries across 
multiple data sets. Several application programming interfaces are also 
available for programmatic access. Here we describe the organization, 
functionality, and capabilities of the ICGC Data Portal.
