Description
This track shows over 8.75 million single nucleotide variants (SNVs)
and over 600,000 insertions or deletions (indels)
as well as exome variant calling regions
in 60,706 unrelated individuals sequenced as part of various population genetic
and disease-specific
studies
collected by the
Exome Aggregation Consortium (ExAC),
release 0.3.
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 release files
README.release0.3
and
README.population_annotations
respectively.
Display Conventions
For the variants subtrack,
in "dense" mode, a vertical line is drawn at the position of each variant.
In "pack" 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 genome annotation is stored in a bigBed file that can be downloaded from the
download server.
The underlying data files for this track are called
ExAC.r0.3.sites.vep.hg19.vcf.gz and exacCallingRegions.bb.
Individual regions or the whole genome annotation can be obtained using 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/ExAC/exacCallingRegions.bb -chrom=chr6 -start=0 -end=1000000 stdout
Please refer to our mailing list archives
for questions, or our Data Access FAQ for more information.
