The tracks listed here contain data from The Genome in a Bottle Consortium (GIAB), an open, public consortium hosted by NIST. The priority of GIAB is to develop reference standards, reference methods, and reference data by authoritative characterization of human genomes for use in benchmarking, including analytical validation and technology development that will support translation of whole human genome sequencing to clinical practice. The sole purpose of this work is to provide validated variants and regions to enable technology and bioinformatics developers to benchmark and optimize their detection methods.

The Ashkenazim and the Chinese Trio tracks show benchmark SNV calls from two son/father/mother trios of Ashkenazi Jewish and Han Chinese ancestry from the Personal Genome Project, consented for commercial redistribution.

The Genome In a Bottle Structural Variants track shows benchmark SV calls (nssv) and variant regions (nsv) (5,262 insertions and 4,095 deletions, > 50 bp, in 2.51 Gb of the genome) from the son (HG002/NA24385) from the Ashkenazi Jewish trio.

Samples are disseminated as National Institute of Standards and Technology (NIST) Reference Materials.

Display Conventions and Configuration

These tracks are multi-view composite tracks that contain multiple data types (views). Each view within a track has separate display controls, as described here.

Unlike a regular genome browser track, the Ashkenazim and the Chinese Trio tracks display the genome variants of each individual as two haplotypes; SNPs, small insertions and deletions are mapped to each haplotype based on the phasing information of the VCF file. The haplotype 1 and the haplotype 2 are displayed as two separate black lanes for the browser window region. Each variant is drawn as a vertical dash. Homozygous variants will show two identical dashes on both haplotype lanes. Phased heterozygous variants are placed on one of the haplotype lanes and unphased heterozygous variants are displayed in the area between the two haplotype lanes.

Predicted de novo variants and variants that are inconsistent with phasing in the trio son can be colored in red using the track Configuration options.

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.

Benchmark VCF and BED files for small variants are available for GRCh37 and GRCh38 under each genome at NCBI FTP site. Structural variants are available for GRCh37 at dbVAR nst175.
