Data schema/format description and download
Source data version: Release 3.0 (October 16, 2019)
Assembly: Human Dec. 2013 (GRCh38/hg38)


The gnomAD v3 track shows variants and derived information from 71,702 whole genomes (and no exomes), all mapped to the GRCh38/hg38 reference sequence. Most of the genomes from v2 are included in v3. For more detailed information on gnomAD v3, see the related blog post.

The gnomAD v2 tracks show variants from 125,748 exomes and 15,708 whole genomes, all mapped to the GRCh37/hg19 reference sequence and lifted to the GRCh38/hg38 assembly. The data originate from 141,456 unrelated individuals sequenced as part of various population-genetic and disease-specific studies collected by the Genome Aggregation Database (gnomAD), release 2.1.1. Raw data from all studies have been reprocessed through a unified pipeline and jointly variant-called to increase consistency across projects. For more information on the processing pipeline and population annotations, see the following blog post and the 2.1.1 README.

gnomAD v2 data are based on the GRCh37/hg19 assembly. These tracks display the GRCh38/hg38 lift-over provided by gnomAD on their downloads site.

On hg38 only, a subtrack "Gnomad mutational constraint" aka "Genome non-coding constraint of haploinsufficient variation (Gnocchi)" captures the depletion of variation caused by purifying natural selection. This is similar to negative selection on loss-of-function (LoF) for genes, but can be calculated for non-coding regions, too. Briefly, for any 1kbp window in the genome, a model based on trinucleotide sequence context, base-level methylation, and regional genomic features predicts expected number of mutations, and compares this number to the observed number of mutations using a Z-score (see Chen et al 2024 in the Reference section for details). The chrX scores were added as received from the authors, as there are no mutations available for chrX, they are more speculative than the ones on the autosomes.

Display Conventions

  • In mode, a vertical line is drawn at the position of each variant.
  • In mode, "ref" and "alt" alleles are displayed to the left of a vertical line with colored portions corresponding to allele counts. Hovering the mouse pointer over a variant pops up a display of alleles and counts.
  • Data Access

    The raw data can be explored interactively with the Table Browser, or the Data Integrator. For automated analysis, the data may be queried from our REST API, and the genome annotations are stored in files that can be downloaded from our download server, subject to the conditions set forth by the gnomAD consortium (see below). Coverage values and constraint scores for the genome are in bigWig files in the coverage/ subdirectory. Variant VCFs can be found in the vcf/ subdirectory.

    The data can also be found directly from the gnomAD downloads page. Please refer to our mailing list archives for questions, or our Data Access FAQ for more information.

    The mutational constraints score ("Gnocchi") was updated in October 2022 from a previous, now deprecated, pre-publication version. The old version can be found in our archive directory on the download server. It can be loaded by copying the URL into our "Custom tracks" input box.


    Thanks to the Genome Aggregation Database Consortium for making these data available. The data are released under the ODC Open Database License (ODbL) as described here.
