TCGA Copy Number Portal (TCGA)

This portal is designed to facilitate the use and understanding of high resolution copy number data amassed from cancer samples in the TCGA. All data in this portal were generated at the Broad Institute TCGA Genome Characterization Center. This portal is modeled after Tumorscape which contains copy number data from non-TCGA projects (Beroukhim et al., 2010).


Gene-Centric GISTIC Analyses

Genes (including miRNAs) can be individually queried by Gene Symbol here. The available data include:

  1. A summary statement of the significance of copy number alterations affecting that gene or transcript.
  2. For amplifications and deletions separately, a table representing the results of GISTIC analyses pertaining to that gene across the entire dataset and within cancer types that are well-represented in the dataset.
  3. Clicking on the chromosome region links displayed on the analyses pages will launch the Integrative Genomics Viewer (IGV) on the data for that region.

Cancer-Centric GISTIC Analyses

Cancer types can be individually queried here. The available data include:

  1. A summary statement of the number of specimens analyzed.
  2. For amplifications and deletions separately, a table representing the results of GISTIC analyses pertaining to that cancer type. The significantly aberrant peak regions of the genome are listed.
  3. Clicking on the chromosome region links displayed on the analyses pages will launch the Integrative Genomics Viewer (IGV) on the data for that region.

Mar 24, 2014: If you experience security barriers opening an IGV session when accessing the portal from a Macintosh with OS X "Mavericks" there is a workaround. The file 'igv.jnlp' is saved to your Downloads Folder. If you open the Downloads Folder in Finder and right click on the IGV icon, then hold down the control key as you select 'Open' from the context menu, you can bypass the security barrier and run IGV.
