## Minimal disambiguation checklist
- Expanded disease name: `________________`
- PMID or article title: `________________`
- Suspected causal gene: `________________`
- Core phenotype triad: `________________ / ________________ / ________________`
- Suspected synonym or legacy name: `________________`
- Inheritance clue: `________________`
- Population / ancestry clue: `________________`

## Next recommended curation actions
1. Search OMIM, Orphanet, MONDO, and MeSH using the **expanded disease name** once known.
2. If a **gene symbol** is known, search ClinVar, ClinGen, GeneReviews, and GTR gene-first.
3. If only phenotype clues are known, search OMIM/Orphanet/HPO using the **phenotype triad**.
4. Record matched identifiers and return to populate each section above with evidence-backed citations.

## Safe-stop statement
- Until the acronym **PCWH** is disambiguated, all disease-specific assertions should remain blank or marked **undetermined** to avoid incorrect knowledge-base entries.
