| Template section | Key fields to populate | Candidate authoritative sources to cite (OMIM/Orphanet/GeneReviews/ClinVar/gnomAD/MGI + PubMed) | Notes |
|---|---|---|---|
| 1. Disease Information | Preferred disease name; WS4 subtype; OMIM/Orphanet/MONDO/MeSH/ICD identifiers; synonyms; concise definition | OMIM; Orphanet; GeneReviews; MONDO; MeSH; PubMed | Add exact cross-references once retrievable evidence is available |
| 2. Etiology | Causal genes (EDN3, EDNRB); mechanism class; inheritance pattern(s); allelic heterogeneity; modifier genes | OMIM; GeneReviews; ClinVar; PubMed | Separate EDN3- vs EDNRB-associated disease where needed |
| 3. Phenotypes | Core clinical features; HPO terms; onset; severity; frequency; progression; QoL impact | OMIM; Orphanet; GeneReviews; PubMed | Include pigmentation anomalies, hearing loss, Hirschsprung disease, and variable neurologic/enteric findings |
| 4. Genetic/Molecular Information | Gene symbols/IDs; variant classes; zygosity; ACMG classification; allele frequencies; germline status; functional consequence | ClinVar; gnomAD; OMIM; GeneReviews; PubMed | Add HGVS examples and founder variants after source retrieval |
| 5. Environmental Information | Non-genetic contributors; modifier exposures; lifestyle/infectious associations if any | PubMed; Orphanet | Likely sparse; mark not established if evidence remains limited |
| 6. Mechanism / Pathophysiology | Endothelin-3/EDNRB signaling; neural crest migration/differentiation; enteric nervous system development; melanocyte biology; GO/CL suggestions | GeneReviews; OMIM; MGI; PubMed | Link upstream pathway disruption to aganglionosis and pigmentary/auditory phenotypes |
| 7. Anatomical Structures Affected | Organs; tissues; cell types; subcellular localization; UBERON/CL/GO CC terms | OMIM; GeneReviews; MGI; PubMed | Focus on colon/enteric nervous system, inner ear, skin/hair/iris melanocyte-containing structures |
| 8. Temporal Development | Congenital/pediatric onset; disease course; lifelong complications; critical intervention windows | Orphanet; GeneReviews; PubMed | Distinguish neonatal bowel obstruction from later supportive management needs |
| 9. Inheritance and Population | AD/AR patterns; penetrance; expressivity; prevalence/incidence; sex ratio; ancestry/geographic distribution; founder effects | Orphanet; OMIM; GeneReviews; gnomAD; PubMed | Populate only with disease-specific estimates, not pooled Waardenburg syndrome data unless clearly labeled |
| 10. Diagnostics | Clinical criteria; differential diagnosis; audiology/ophthalmology/gastrointestinal workup; pathology; molecular testing strategy; WES/WGS utility | GeneReviews; OMIM; ClinVar; PubMed | Include differential diagnosis vs SOX10/PAX3/MITF-related syndromes and isolated Hirschsprung disease |
| 11. Outcome/Prognosis | Surgical outcomes; complications; morbidity; hearing/language outcomes; survival/life expectancy; prognostic factors | Orphanet; GeneReviews; PubMed | Prognosis may depend strongly on extent of aganglionosis and timeliness of management |
| 12. Treatment | Hirschsprung surgery; hearing rehabilitation; ophthalmic/dermatologic care; developmental support; experimental therapies; MAXO terms | GeneReviews; Orphanet; PubMed; ClinicalTrials.gov | Likely no gene-targeted therapy; emphasize multidisciplinary management |
| 13. Prevention | Genetic counseling; cascade testing; carrier testing; prenatal diagnosis; PGT; newborn/early detection considerations | GeneReviews; Orphanet; PubMed | Prevention is mainly reproductive and complication-prevention rather than primary biologic prevention |
| 14. Other Species / Natural Disease | Orthologous genes; natural disease in animals; comparative pathology; veterinary relevance | MGI; PubMed | Add OMIA or veterinary sources if retrievable in a future run |
| 15. Model Organisms | Mouse/zebrafish/cellular models; knockout/knock-in systems; phenotype recapitulation; limitations; research applications | MGI; IMPC; PubMed | Prioritize Ednrb/Edn3 models showing aganglionosis and pigment defects |
| Cross-cutting evidence table | PMID/DOI; year; study type; cohort size; genotype; phenotype summary; quoted abstract evidence | PubMed | Create after successful document retrieval and context generation |
| Variant curation appendix | Variant-level assertions; submitter consensus; population frequency; segregation; functional assay summary | ClinVar; gnomAD; PubMed | Useful for knowledge-base ingestion and ACMG-style interpretation |
| Recent developments (2023-2024) | New case reports/cohorts; expanded phenotypes; new variants; updated testing workflows | PubMed | Reserve a dedicated subsection for recent literature once retrieval succeeds |
| Citation audit trail | Source URL; access/publication date; identifier mapping; evidence level | OMIM; Orphanet; GeneReviews; ClinVar; gnomAD; MGI; PubMed | Needed to convert this scaffold into a fully evidence-grounded report |
| Run-status note | Retrieval success/failure; missing context IDs; unresolved evidence gaps | Internal workflow outputs | Current scaffold exists because prior run returned no citable contexts |


*Table: This table provides a structured placeholder scaffold for a future evidence-grounded report on EDN3/EDNRB Waardenburg–Shah syndrome. It maps each template section to the fields and source types that should be populated once authoritative retrievable references are available.*
