Genome Aggregation Database (gnomAD)

The Genome Aggregation Database (gnomAD) is a resource developed by an international coalition of investigators, with the goal of aggregating and harmonizing both exome and genome sequencing data from a wide variety of large-scale sequencing projects, and making summary data available for the wider scientific community.

Data source

This dataset is hosted as a collaboration with the Broad Institute and the full gnomAD data catalog can be seen at

Data volumes and update frequency

This dataset contains approximately 30 TB of data and is updated with each gnomAD release.

Storage location

The Storage Account hosting this dataset is in the East US Azure region. Allocating compute resources in East US is recommended for affinity.

Data Access

Storage Account: ''

The data is available publicly without restrictions, and the AzCopy tool is recommended for bulk operations. For example, to view the VCFs in release 3.0 of gnomAD:

$ azcopy ls

To download all the VCFs recursively:

$ azcopy cp --recursive=true .

NEW: Parquet format of gnomAD v2.1.1 VCF files (exomes and genomes)

To view the parquet files:

$ azcopy ls

To download all the parquet files recursively:

$ cp --recursive=true

The Azure Storage Explorer is also a useful tool for browsing the list of files in the gnomAD release.

Use Terms

Data is available without restrictions. For more information and citation details, see the gnomAD about page.
