| Section | Placeholder content to fill later with citations |
|---|---|
| Disease Information | Add concise definition; authoritative identifiers (OMIM, Orphanet, ICD, MeSH, MONDO); synonyms; note whether statements come from aggregated resources or patient-level reports. |
| Etiology | Add causal mechanism; gene(s) and inheritance; known risk/protective factors; gene-environment interactions; specify evidence strength. |
| Phenotypes | Add core symptoms/signs; HPO terms; age at onset, severity, progression, frequency, and quality-of-life impact for each feature. |
| Genetic / Molecular Information | Add causal gene details (PAX3), variant classes, representative HGVS examples, ClinVar/ClinGen status, allele frequency, functional consequences, modifier genes, epigenetic or chromosomal findings. |
| Environmental Information | Add any validated non-genetic contributors, lifestyle modifiers, exposures, or infectious triggers; mark not applicable if unsupported. |
| Mechanism / Pathophysiology | Add causal chain from variant to phenotype; pathways, cell types, protein dysfunction, tissue effects, and suggested GO/CL terms. |
| Anatomical Structures Affected | Add organ, tissue, cell-type, and subcellular localization with UBERON/CL/GO-CC mappings and lateralization if relevant. |
| Temporal Development | Add congenital/pediatric/adult onset, disease course, progression pattern, duration, and critical intervention windows. |
| Inheritance and Population | Add inheritance pattern, penetrance, expressivity, prevalence/incidence, demographics, founder effects, and geographic distribution. |
| Diagnostics | Add clinical criteria, differential diagnosis, laboratory/imaging/functional tests, hearing assessment, and recommended genetic testing workflow (single gene, panel, WES/WGS, CMA if relevant). |
| Outcome / Prognosis | Add morbidity, functional outcomes, complications, life expectancy/survival if known, and prognostic factors/biomarkers. |
| Treatment | Add supportive care, hearing interventions, rehabilitation, surgical options if relevant, counseling, experimental therapies/trials, outcomes, adverse effects, and MAXO terms. |
| Prevention | Add cascade screening, reproductive counseling, prenatal/preimplantation options, early hearing surveillance, and tertiary prevention of complications. |
| Other Species / Natural Disease | Add naturally occurring homologous disease in animals, orthologous genes, comparative pathology, and veterinary relevance. |
| Model Organisms | Add mouse/zebrafish/cellular models, phenotype recapitulation, limitations, and key databases/resources. |
| Evidence Gaps / Notes | Record missing data, contradictory findings, unavailable statistics, and fields requiring targeted literature follow-up. |
