# Population data tracks

These tracks help you compare case findings against internal and public population data.

## Organization DB

**\[Organization DB]** tracks display variants from [organization databases](/emedgene/emedgene-analyze-manual/settings/organization_settings_-330+/workbench-and-pipeline/organization-db-management/organization-databases.md).

Left-click a variant to review variant details from the database:

* Allele frequency
* Allele count and allele number
* Heterozygote and homozygote or hemizygote counts
* Sample IDs where the variant was last observed

## gnomAD SV

The **gnomAD SV** track displays structural variants from gnomAD.

Use it to review population frequency and distribution across diverse cohorts to support clinical relevance assessment.

## DGV Gold

The **DGV Gold** track displays high-confidence structural variants curated by the Database of Genomic Variants.

Use it as a reference for common benign structural variants.

## Decipher Healthy Population

The **Decipher Healthy Population** track displays variants observed in healthy individuals from the Deciphering Developmental Disorders study.

Use it to compare findings against a baseline of unaffected genomes.
