The Open-Access Data tier is a publicly accessible tier of data that cannot be aggregated to generate a dataset unique to an individual. The Open-Access Data tier does not require user certification for data access.

Data within the Open-Access Data Tier are available in public databases, such as TCGA Data Portal and the NCBI Trace Repository. These data types may include:

• Tissue pathology data,
• Health Insurance Portability and Accountability Act of 1996 (HIPAA) de-identified clinical data,
• Gene expression data,
• Copy-number alterations for non-genetic platforms,
• Epigenetic data,
• Data summaries, such as genotype frequencies, and
• DNA sequence data of single amplicons.
