Add Noonan Syndrome with debundled pathophysiology

[cmungall]

Summary

• Adds new disorder entry for Noonan syndrome (MONDO:0018997)
• Pathophysiology decomposed into atomic processes per many pathophys entries need to be split/debundled #164:
  • SHP2 Gain-of-Function Activation → ERK Cascade Hyperactivation
  • SOS1-Mediated RAS-GTP Loading → ERK Cascade Hyperactivation
  • RAF1 Kinase Hyperactivation → ERK/Cardiomyocyte Hypertrophy
  • RIT1-Mediated RAF Recruitment → ERK/Cardiomyocyte Hypertrophy
  • LZTR1-Mediated RAS Proteostasis Defect → ERK Cascade Hyperactivation
  • ERK Cascade Hyperactivation → Cardiac Valve Defects + Cardiomyocyte Hypertrophy
• Explicit downstream causal edges create a queryable mechanistic graph
• 16 phenotypes with HPO terms, 6 genes with HGNC terms, 6 treatments with MAXO terms
• Evidence from landmark papers (PMIDs: 11992261, 17143285, 17603483, 23791108)

Validation

✅ Schema validation passed
✅ Term validation passed (100% term coverage)
✅ Reference validation passed
📊 Compliance: 68% (expected lower due to new downstream edge evidence requirements)

PR Review Complete ✅

I've conducted a comprehensive review of the Noonan Syndrome disorder entry and associated files. Here's my detailed feedback:

Todo List

• Read repository guidelines (CLAUDE.md)
• Review main disorder file structure and content
• Examine research files for appropriateness
• Check ontology term usage and compliance
• Assess evidence quality and references
• Review pathophysiology debundling implementation
• Provide comprehensive feedback

---

Code Quality Assessment: ⭐⭐⭐⭐☆ (4/5)

✅ Excellent Aspects

1. Pathophysiology Debundling Implementation

• Outstanding implementation of atomic pathophysiology processes with explicit downstream relationships
• Creates a clear mechanistic graph structure as intended in issue many pathophys entries need to be split/debundled #164
• Proper convergence on "ERK Cascade Hyperactivation" as the unifying pathophysiological node
• Well-structured causal graph: Gene Defects → ERK Hyperactivation → Tissue-Specific Phenotypes

2. Evidence Quality

• Uses high-quality landmark papers (PMIDs: 11992261, 17143285, 17603483, 23791108)
• Evidence snippets appear to be exact quotes from abstracts (following CLAUDE.md SOP)
• Proper evidence source classification (HUMAN_CLINICAL)
• Strong correlation between evidence and pathophysiology claims

3. Ontology Term Usage

• Comprehensive coverage: 16 HPO phenotypes, 6 HGNC genes, 6 MAXO treatments
• Proper use of GO terms for biological processes (e.g., GO:0004725 for phosphatase activity)
• Anatomical terms from UBERON (pulmonary valve, heart)
• Cell type annotations from CL (endocardial cell, cardiomyocyte)

4. Schema Compliance

• Follows LinkML schema structure correctly
• Proper use of preferred_term patterns
• Consistent frequency classifications (VERY_FREQUENT, FREQUENT, OCCASIONAL)
• Diagnostic phenotype marking for key features

⚠️ Areas for Improvement

1. Research Files Placement

• Issue: Research markdown files (research/Noonan_Syndrome-deep-research-falcon.md*) are added to the repository
• Concern: These appear to be AI-generated research artifacts that may not need version control
• Recommendation: Consider if these should be .gitignored or if they serve a specific documentation purpose

2. Missing Evidence for Some Pathophysiology Steps

• Issue: LZTR1-Mediated RAS Proteostasis Defect (lines 120-138) lacks evidence items
• Impact: This breaks the evidence coverage pattern seen in other pathophysiology entries
• Recommendation: Add supporting evidence or move unsupported mechanisms to notes

3. Treatment Evidence Gaps

• Issue: MEK Inhibitor Therapy (lines 577-599) describes "case reports" but provides no evidence items
• Risk: Unsupported treatment claims could mislead clinicians
• Recommendation: Either add specific PMID evidence or clearly mark as experimental/investigational

4. Genotype-Phenotype Correlations

• Observation: While individual genes mention HCM associations in notes, the phenotype entries could better cross-reference specific genetic subtypes
• Enhancement: Consider adding genotype-specific frequency annotations

🔒 Security Concerns

• Low Risk: No security issues identified - purely scientific knowledge base content

📊 Performance Considerations

• Positive: Well-structured YAML will parse efficiently
• Note: File size (634 lines) is reasonable and consistent with other disorder entries

🧪 Test Coverage Assessment

• Schema Validation: Should pass based on structure
• Expected Behavior: Will integrate with existing test suite in tests/test_data.py
• Note: Validation commands require approval, but structure appears compliant

📝 Best Practices Compliance

Follows Repository Guidelines:

• ✅ Evidence snippets follow exact quote requirements
• ✅ Ontology term patterns match canonical labels
• ✅ MAXO treatment terms properly structured
• ✅ Proper inheritance pattern documentation
• ✅ Frequency classifications align with guidelines

Debundling Pattern Success:

• ✅ Atomic processes with clear biological functions
• ✅ Explicit downstream relationships
• ✅ Convergent pathophysiology design
• ✅ Tissue-specific endpoints

Recommendations for Approval

High Priority:

1. Add evidence for LZTR1 pathophysiology mechanism
2. Provide PMID evidence for MEK inhibitor therapy claims
3. Clarify purpose of research files in repository

Medium Priority:
4. Consider adding genotype-phenotype cross-references
5. Review research file inclusion policy

Overall Assessment: This is a high-quality contribution that successfully implements the debundled pathophysiology pattern. The mechanistic detail is excellent and the evidence base is strong. With minor evidence gaps addressed, this would be an exemplary disorder entry.

Pull request overview

This PR adds a comprehensive disorder entry for Noonan Syndrome (MONDO:0018997), a RASopathy caused by germline mutations in the RAS-MAPK signaling pathway. The key contribution is the implementation of debundled pathophysiology as outlined in issue #164, where the pathophysiological mechanisms are decomposed into atomic processes connected through explicit causal relationships using downstream edges.

Changes:

• Introduced a novel causal graph structure for Noonan syndrome pathophysiology with 8 mechanistic nodes (5 upstream genetic defects → ERK hyperactivation → 2 terminal phenotypic outcomes)
• Added comprehensive phenotype annotations (16 phenotypes), genetic associations (6 genes), and treatment options (6 interventions)
• Included evidence from 4 landmark papers (PMIDs: 11992261, 17143285, 17603483, 23791108) with appropriate snippets and explanations
• Generated supporting research documentation from scientific literature

File	Description
kb/disorders/Noonan_Syndrome.yaml	Main disorder entry with debundled pathophysiology graph, phenotypes, genetic associations, and treatments

[Copilot]

The UBERON ID for "pulmonary valve" appears to be incorrect. The research documentation (research/Noonan_Syndrome-deep-research-falcon.md line 183) indicates the correct UBERON ID is UBERON:0002133, but the YAML file uses UBERON:0002146. This should be verified and corrected to ensure the ontology term reference is accurate.

Suggested change

	id: UBERON:0002146
	id: UBERON:0002133

[cmungall]

That's the ID for AV valve. While it may be the case this kind of pulmonary valve is implicated, it's not justified in the excerpt below, and your justification pulled from the the deep research is a bit random.

@copilot you're not hooked up to use the claude code setup here you should rectify that then you'll make fewer errors

[Copilot]

@cmungall I've opened a new pull request, #246, to work on those changes. Once the pull request is ready, I'll request review from you.
