varFreqs: Phase-7 audit cleanup on the supertrack and combined-track
description pages.
Supertrack varFreqs.html:
- Restore the consequence-filter "Other" bucket explanation that was lost
when varFreqsAll.html was replaced by the Affected+Background pair (now
documented once on the supertrack page, since all three combined tracks
share the filter).
- Add 6 primary citations that were already in standalone subtrack pages
but not carried up: Bycroft (UK Biobank), Cao (ChinaMAP), Cong (WBBC),
Genome of the Netherlands Consortium (GoNL), Malomane (Saudi), Yang
(TPMI).
- Reorder Ameur, Singh into correct alphabetical position.
- Lowercase Description
This track collection gathers variant allele frequencies from population-scale sequencing
and genotyping projects worldwide, from a total of ~1.7 million genomes/exomes/arrays.
The data was not reprocessed in a harmonized way; the variant VCFs were collected from the
projects as-is. The goal is a single place to compare how common a variant is across
different populations, ancestries, and cohorts, for projects that cannot be recomputed by
gnomAD soon. Three combined tracks aggregate the source data along different lines, and
there is also one subtrack per project with the original VCF data and all the annotations
that the project provides. The different projects use different pipelines and sequencing
technologies. Click any of the projects above or below for a summary of their sample
selection, sequencing assay and software pipeline. Many projects do not allow us to
distribute the data, but we document how to request it and provide all converters.
Data from projects that provide haplotype-phased genotypes can also be found
elsewhere: 1000 Genomes is also a separate track, and the phased genotypes HGDP, SGDP,
HGDP+1000 Genomes and Mexico Biobank can also be found in the "Phased Variants" track.
Their VCF versions below show only the isolate frequency per variant.

Three combined tracks merge variants from the individual subtracks into single bigBed files
with predicted protein consequences and cross-database filtering. All three use the same
filter conventions (variant type, consequence, source database, allele frequency, allele
count, and per-database AF/AC).
+All three combined tracks share the same Consequence filter (Missense, Synonymous, Stop
+Gained, Frameshift, Splice Donor, Splice Acceptor, Intron, 3' UTR, 5' UTR, Non-coding,
+Intergenic, Other). The filter uses OR logic across the comma-separated consequence tokens
+on each variant: a variant tagged Combined Tracks
+Consequence filter — the "Other" bucket
+stop_gained,frameshift is selected by either
+the "Stop Gained" or the "Frameshift" filter. The "Other"
+bucket catches the less common
+Sequence Ontology consequence
+terms emitted by bcftools csq that don't fit the named buckets above. Examples
+include splice_region (variant near a splice site but outside the canonical
+donor/acceptor), start_lost / stop_lost (variant disrupts the
+start codon or replaces the stop codon with a coding amino acid),
+stop_retained (variant changes the stop codon but keeps it a stop),
+inframe_insertion / inframe_deletion (in-frame indel that adds or
+removes whole codons), and coding_sequence (CDS variant where the precise
+impact is undetermined). If you include "Other" in the filter selection, no
+records will be hidden by the consequence filter.

The AllOfUs subtrack provides local-ancestry-stratified allele frequencies, not the global ancestry categories used in the All of Us Research Program 2024 Nature paper (see References). Each variant's per-ancestry AF/AC counts only the haplotypes whose inferred local ancestry at that exact genomic position belongs to the named group (strict-both-haps mode). The six ancestry classes (African, Indigenous American, East Asian, European, Oceanian, South Asian) match HGDP-derived local-ancestry reference panels and so include Oceanian, which is not one of the paper's six global Rye categories (those are AFR, AMR, EAS, EUR, Middle Eastern, SAS). For an admixed individual, the local-ancestry AF at a position can therefore differ substantially from the AF among self-reported members of the same ancestry group. The Ioannidis lab (Phoenix, UCSC) developed the pipeline that produced this VCF and applied it to the AllOfUs v7 release; only variants with cohort allele count ≥ 20 were retained.
This subtrack derives from the gnomAD v3.1.2 release, which embeds the 4,094-genome jointly-called HGDP+1kG cohort (Koenig et al. 2024) inside the larger gnomAD aggregation. To save space, we kept only INFO fields useful for clinical and population-genetic interpretation. Two allele-frequency sets are exposed:
The filter labels on the track configuration page, and the field descriptions in the combined-track bigBed, reflect this distinction. Per-population HGDP+1kG-cohort frequencies are not exposed because the cohort is too small for stable per-population estimates in many populations.
Most tracks only show the variant and allele frequencies on mouseover or clicks. When zoomed in, tracks display alleles with base-specific coloring. Homozygote data are shown as one letter; heterozygotes are shown with both letters. All VCF files are normalized, with one allele per annotation (no multi-allele lines).
Each subtrack includes the upstream project's VCF largely as-released; per-subtrack pipelines
(coordinate liftover, format conversion, header normalization) are documented on each
subtrack's own description page and recorded in the
build documentation.
The conversion scripts (e.g. finngen_to_vcf.py, kovaToVcf.py,
schema_addAcAnAf.py, svatalogFreqToVcf.py) live alongside the makedoc
in the scripts directory.
The combined Affected and Background tracks are built by a separate pipeline:
each per-subtrack VCF is normalized (bcftools norm), all sites are merged into a single
callset, consequence annotations are recomputed against Ensembl with bcftools csq,
and the merged callset is split by phenotype into the two bigBed files via
vcfToBigBed.py + bedToBigBed. The mapping from upstream INFO fields to
bigBed columns is driven by two configuration files in the scripts directory:
databases.tsv (one row per source dataset, flagging which cohorts study a disease)
and populations.tsv (per-population AC/AF columns within each source, including the
affected and unaffected arm of each disease cohort). Editing those two files and rerunning
mergeAndAnnotate.sh followed by vcfToBigBed.py --split-affected rebuilds
the two tracks. The Genotyping Array Databases Combined track is built the same way from the
array cohorts only.
All the data is publicly available. The table above indicates if we are allowed to distribute it in VCF format. Most of the databases do not allow us to redistribute the data files directly from our website, but it can always be downloaded from the original websites in some form. Click the database link in the table above and see the "Data Access" section of the respective track for a description of where to download the data. When the data is freely available from our website, the Data Access section will also indicate the VCF file location on our download server. Because it contains some licensed data, the combined track is not available for download, but can be recreated using the conversion scripts in our GitHub repository and the accompanying documentation file.
This track is only possible thanks to the data from millions of volunteers around the world, who donated blood, signed consent forms and provided health information about themselves and sometimes their families. Click any of the tracks in the list above to see the specific credits for each project. Thanks to Alex Ioannidis, UCSC, for the inspiration for this track and to Andreas Lahner, MGZ, for feedback.
