gnomad-variants

What problem does it solve?

This Skill enables querying gnomAD for detailed allele frequencies, population data, and gene constraint scores essential for interpreting ENCODE regulatory variants.

Core Features & Use Cases

• Variant Frequency Analysis: Retrieve population-specific and global allele frequencies for genomic variants.
• Gene Constraint Assessment: Access LOEUF, pLI, and other metrics to evaluate gene intolerance to loss-of-function mutations.
• Use Case: When analyzing a regulatory variant within an ENCODE peak, check if it is rare in relevant populations and whether its target gene is highly constrained, prioritizing variants for functional validation.

Quick Start

Query gnomAD for the allele frequency of a specific variant to determine its rarity in different populations and evaluate gene constraint scores to assess potential pathogenicity.
