Description

The Genome Aggregation Database (gnomAD) - Structural Variants track set shows structural variants calls (>=50 nucleotides) from the gnomAD v2.1 release on 10,847 unrelated genomes. It mostly (but not entirely) overlaps with the genome set used for the gnomAD short variant release. For more information see the following blog post, Structural variants in gnomAD.

There are three subtracks in this track set:

  1. All SV's: The full set of variant annotations from all 10,847 samples.
  2. Control Only SV's: Only samples from individuals not selected as a case in a case/control study of common disease (5,192 samples).
  3. Non-neuro SV's: Only samples from individuals not selected as having a neurological condition in a case/control study (8,342 samples).

Display Conventions and Configuration

Items in all subtracks follow the same conventions: items are shaded according to variant type, mouseover on items indicates affected protein-coding genes, size of the variant (which may differ from the chromosomal coordinates in cases like insertions), variant type (insertion, duplication, etc), Allele Count, Allele Number, and Allele Frequency. When more than 2 genes are affected by a variant, the full list can be obtained by clicking on the item and reading the details page. A short summary of the 3 datasets is available in the below table:

Variant Type All Controls Non-neuro
Breakend (BND) 52604 37891 44952
Complex (CPX) 4778 3129 4167
Translocation (CTX) 8 4 5
Deletion (DEL) 169635 116401 145978
Duplication (DUP) 49571 36223 43916
Insertion (INS) 109025 78475 95658
Inversion (INV) 748 492 667
Multi-Allele CNV (MCNV) 1108 1108 1108

All tracks can be filtered according to the size of the variant and variant type.

Methods

Bed files were obtained from the gnomAD Google Storage bucket:

gsutil cp gs://gnomad-public/papers/2019-sv/gnomad_v2.1_sv.*.bed*
These data were then transformed into bigBed tracks. For the full list of commands used to make this track please see the "gnomAD Structural Variants v2.1" section of the makedoc.

Data Access

The raw data can be explored interactively with the Table Browser, or the Data Integrator. For automated access, this track, like all others, is available via our API. However, for bulk processing, it is recommended to download the dataset. The genome annotation is stored in a bigBed file that can be downloaded from the download server. The exact filenames can be found in the track configuration file. Annotations can be converted to ASCII text by our tool bigBedToBed which can be compiled from the source code or downloaded as a precompiled binary for your system. Instructions for downloading source code and binaries can be found here. The tool can also be used to obtain only features within a given range, for example:

bigBedToBed http://hgdownload.soe.ucsc.edu/gbdb/hg19/gnomAD/structuralVariants/gnomad_v2.1_sv.sites.bb -chrom=chr6 -start=0 -end=1000000 stdout

Please refer to our mailing list archives for questions and example queries, or our Data Access FAQ for more information.
