Accessing Genomic Data

The GDC Data Portal is a groundbreaking tool that enables a better understanding of cancer biology by allowing researchers to:

  • Search and query genomic data
  • Download data directly from the web browser or download large volumes of data using the high performance GDC Data Transfer Tool
  • Analyze cancer data including clinical information, genomic characterization data, and high level sequence analysis of the tumor genomes

Data Access Tools

The GDC provides web-based tools and API endpoints for searching, viewing and downloading data as well as client tools for downloading large volumes of data.

Controlled Data Access Policy

Any user requesting access to GDC controlled data must apply for access to the data through the database of Genotypes and Phenotypes (dbGaP):

High Quality Datasets

The GDC obtains datasets from NCI programs which maintain tissue collection strategies that couple quantity with quality. Data validation is performed on all data submitted to the GDC.

From the GDC FAQ

Where can I find clinical data elements specific to my cancer research of interest?

The GDC supports the submission of clinical and biospecimen supplements. Supplemental files can be downloaded from the GDC by searching for the Data Type "Clinical Supplement" or "Biospecimen Supplement" from the facet search in the GDC Data Portal Repository. For TCGA data, the supplement data is provided in XML documents and tab delimited files (biotabs). These files, in varying degrees, provide information on marker status (e.g. EBV status), treatment regimen, slide magnification, histology distinctions, and staging questions.
