Raras Brazilian Rare Disease Knowledge Graph

Raras is an open, FAIR-compliant knowledge graph of rare diseases — the largest in Latin America — integrating Orphanet, the Human Phenotype Ontology (HPO), OMIM, MONDO, ClinVar, Open Targets, PubMed and ClinicalTrials.gov with Brazilian public-health (SUS) data. It mints stable RARAS identifiers for diseases, reference centers, protocols, associations, communities and medications, each resolvable as Linked Data (SPARQL, RDF, GraphQL, GA4GH Beacon/Phenopackets) with a dereferenceable vocabulary and VOID/DCAT metadata.
