Description
Variants from the dbVar study nstd186 (NCBI Curated Common Structural Variants), which is a curated collection of structural variants from studies with at least 100 samples, include allele frequency data, and have an allele frequency of >=0.01 in at least one population. Separate subtracks allow distinction between different populations and original data sources. Allele frequencies are aggregated on these super-populations: global, African, American, East Asian, European, South Asian, other. This track includes copy number variations, gains, duplications, insertions, losses, and deletions. For questions about dbVar track data, please contact dbvar.
Data Updates
nstd186 (NCBI Curated Common Structural Variants) combines data from multiple studies in dbVar. A detailed summary and history of nstd186 can be found in the summary page of Common variants in dbVar.
This track contains data from the following studies:
Subtracks
The NCBI Curated Common Structural variants are separated into subtracks according to population and data source:
Non-Redundant
Except for the _Only_ subtracks, this track is non-redundant with respect to placement and variant type. The label contains the values of the variant with the highest allele frequency at the placement and variant type.
Display Conventions and Configuration
Labels
The variant label is the dbVar variant call accession (nssv).

Placements
For simplicity, the BED files and tracks only contain the variants' outer-most start and stop placements. The actual variant placements may consist of exact start/stop with breakpoint resolution, inner-placements only, outer-placements-only, or some combination. For full details of variant placements, follow the links to the variant pages in dbVar.

Data Access
Data for this track can be downloaded from the following locations:
Methods
Generating the NCBI Curated Common Structural Variant Tracks consists of the following:
- loading and accessioning large population studies with frequency data into dbVar
- selecting common variants based on the criteria of at least 100 samples and allele frequency >= 0.01
- generating a unique dbVar variant call for each common variant
- generating a unique dbVar variant region for each unique set of variant call placements
- loading common variants as dbVar study nstd186
- assigning dbVar accessions:
- nssv: variant call
- nsv: variant region (from multiple calls with the same placements)
- remapping variants to GRCh37 and GRCh38
- adding length ranges for filtering
- adding frequency ranges for filtering
- excluding placements not on finished chromosomes
- reducing to non-redundant with respect to placement and variant type
- generating bigBed file
