gnomad-database

What problem does it solve?

This Skill allows users to query the Genome Aggregation Database (gnomAD) to retrieve population variant frequencies, gene constraint metrics, and coverage data, enabling researchers to assess variant rarity and evolutionary constraint.

Core Features & Use Cases

• Variant Frequency Lookup: Retrieve allele counts and frequencies for specific variants across multiple ancestry groups.
• Gene Constraint Analysis: Obtain gene-level scores like pLI and LOEUF to understand a gene's tolerance to loss-of-function mutations.
• Coverage Assessment: Check read depth coverage for genomic regions to evaluate data quality.
• Use Case: A researcher identifies a novel variant in a patient's exome data. They can use this Skill to query gnomAD to determine if the variant is common in any population, which is a crucial step in assessing its potential pathogenicity.

Quick Start

Use the gnomad-database skill to get the pLI and LOEUF scores for the gene BRCA1.
