SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

The Monarch Initiative Database empowers researchers to query across species for disease-gene-phenotype associations by integrating OMIM, ORPHANET, HPO, ClinVar, and model organism data to accelerate rare-disease discovery and translational research.

Core Features & Use Cases

  • Cross-species disease-gene-phenotype mapping to identify candidate genes and model organisms for a given phenotype or disease.
  • HPO term lookup and MONDO ontology integration to harmonize queries across sources.
  • Phenotype-to-disease and gene-to-phenotype associations to support rare-disease gene prioritization and cross-species disease modeling.

Quick Start

Query Monarch API v3 to retrieve genes associated with a given HPO term, or diseases linked to a gene.

FAQPage Schema
How do I map human phenotype ontology terms to candidate genes across species?

To map HPO terms to candidate genes across species, query the Monarch Initiative knowledge graph to retrieve cross-species disease-gene-phenotype associations using HPO identifiers and orthology data.

What is cross-species disease modeling and when do I need it for rare disease discovery?

Cross-species disease modeling integrates model organism data with OMIM, ORPHANET, and ClinVar to identify candidate genes. You need it for rare-disease discovery and translational research when human data is limited.

Can I retrieve disease associations for a specific gene using MONDO identifiers?

Yes, you can retrieve disease associations for a specific gene by querying Monarch API v3 endpoints with MONDO identifiers to aggregate cross-ontology relationships and disease-gene-phenotype mappings.

Does the Monarch knowledge graph integrate model organism data with human disease ontologies?

Yes, the Monarch knowledge graph integrates model organism data with human disease ontologies by harmonizing HPO and MONDO terms across OMIM, ORPHANET, and ClinVar sources for cross-species queries.

What's the best way to prioritize candidate genes for rare diseases using phenotype-to-gene mapping?

The best way to prioritize candidate genes is leveraging phenotype-to-gene associations through the Monarch API v3, querying HPO terms and orthology data to map phenotypes to potential disease-causing genes across species.
