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.

Does the GDC provide access to follow-up (i.e. longitudinal) data?
The availability of follow-up data is specific to the project and associated study.
For the Multiple Myeloma Research Foundation (MMRF) Clinical Outcomes in Multiple Myeloma to Personal Assessment of Genetic Profile (CoMMpass) study, longitudinal information was generated to track patients over the course of their disease. This data is available in the GDC by viewing the clinical follow-up data available for download on each case page in the GDC Data Portal or by querying the GDC API.
For TCGA, follow-up data is available for specific TCGA studies and made available for download in associated clinical supplement files (i.e. clinical XML, biotabs). Follow-up data can be different for the different TCGA studies.
