variant_searcher
Retrieve detailed genetic variant records, including population frequencies, clinical significance, and functional predictions, from MyVariant.info. Search by gene, HGVS notation, rsID, or genomic region, and filter by clinical or functional criteria to refine results.
Instructions
Search MyVariant.info for genetic variant DATABASE RECORDS.
⚠️ PREREQUISITE: Use the 'think' tool FIRST to plan your research strategy!
Important: This searches for variant DATABASE RECORDS (frequency, significance, etc.),
NOT articles about variants. For articles about variants, use article_searcher.
Searches the comprehensive variant database including:
- Population frequencies (gnomAD, 1000 Genomes, etc.)
- Clinical significance (ClinVar)
- Functional predictions (SIFT, PolyPhen, CADD)
- Gene and protein consequences
Search by various identifiers or filter by clinical/functional criteria.Input Schema
