SPARC/dbGaP Quick-Reference

Under the NIH Genomic Data Sharing (GDS) Policy, read-level human genomic data must be deposited in a controlled-access repository such as dbGaP. If data does not require controlled access, it can be deposited in SPARC. Responsibility for regulatory compliance remains with the data submitter and Principal Investigator.

This information is provided for general demonstration purposes and is not a substitute for regulatory guidance. Ultimate responsibility for compliance with all applicable mandates — including the NIH Genomic Data Sharing Policy — rests solely with the investigator and Principal Investigator.

⚠️ Note: This table is a non-exhaustive quick-reference. Companion and index files (.bai, .csi, .tbi, .crai) that enable interpretation or reconstruction of underlying controlled-access genomic data are also subject to controlled-access deposition requirements. For ambiguous cases, consult your NIH Genomic Program Administrator (GPA) before depositing.
