SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

GWAS studies produce lists of disease-associated variants, but turning those statistical hits into mechanistic insight and actionable drug targets requires chaining together variant annotation, eQTL evidence, pathway enrichment, and druggability analysis across many databases. This Skill orchestrates that entire workflow so researchers can trace SNPs to causal genes, genes to pathways, and pathways to existing or novel drug targets.

Core Features & Use Cases

  • GWAS-to-Gene Mapping: Collect genome-wide significant variants from the GWAS Catalog, annotate them with Ensembl VEP, and prioritize causal genes using GTEx eQTL evidence in disease-relevant tissues.
  • Cross-Database Pathway Enrichment: Run enrichment across Reactome, KEGG, STRING, and PANTHER, then prioritize pathways that converge across multiple databases for stronger mechanistic evidence.
  • Druggability and Drug Landscape Analysis: Assess pathway members with DGIdb and Open Targets to classify candidates as repurposing opportunities, clinical-stage validations, or novel targets.
  • Use Case: Given type 2 diabetes GWAS hits, identify that multiple genes converge on Wnt signaling, confirm eQTL evidence in pancreatic tissue, and surface approved drugs hitting pathway members as repurposing candidates.

Quick Start

Use the pathway-disease-genetics skill to map GWAS hits for type 2 diabetes to causal genes, enriched pathways, and druggable targets.

FAQPage Schema
How do I map GWAS variants to causal genes and pathways?

Pull genome-wide significant variants with gwas_get_variants_for_trait, annotate them with Ensembl VEP, then check GTEx eQTL evidence in disease-relevant tissues to prioritize causal genes. Run the resulting gene list through Reactome and STRING enrichment to identify convergent pathways.

How do I find drug targets from GWAS data for a disease?

Extract member genes from enriched pathways using Reactome_get_participants, assess druggability with DGIdb_get_gene_druggability, and look up existing drugs via Open Targets. Candidates are classified as repurposing opportunities, clinical-stage validations, or novel targets.

Why is gwas_get_associations_for_trait not working?

The gwas_get_associations_for_trait tool is broken; use gwas_search_associations instead for broad association searches. Also note that gwas_get_snps_for_gene requires the gene_symbol parameter, not mapped_gene.

What input format does Reactome pathway enrichment require?

ReactomeAnalysis_pathway_enrichment expects identifiers as a space-separated string of UniProt IDs, not an array. PANTHER_enrichment similarly takes a comma-separated string for gene_list rather than an array.

What are the limitations of GTEx eQTL evidence for causal gene mapping?

GTEx eQTL lookup is not formal statistical colocalization like coloc or ENLOC, so treat it as suggestive evidence only. eQTLs are also tissue-specific, so querying the wrong tissue may miss causal effects.

Can I use MetaCyc for metabolic pathway analysis?

MetaCyc is currently unavailable because BioCyc requires authentication. Use KEGG or Reactome instead for metabolic pathway enrichment and gene-to-pathway mapping.
