# HTAN Data Access Levels

HTAN data is categorized into two data access levels:

  • Open access: includes de-identified clinical and biospecimen data, multiplex images, and processed genomic data. This data is available via the HTAN Data Portal. See Open Access Data.

  • Access controlled: includes unprocessed genomic data, e.g. BAM files. Similar to TCGA BAM files, this data is available via an approved dbGaP mechanism. See Controlled-Access Data.
