## CORE CONCEPT

Structure clinical reasoning through domain-specific columns—each representing a distinct biological or clinical system—then map how these systems interact in the patient. Think in layers; speak like a clinician. Use multi-column analysis when patients present with complex, multi-system involvement or when genomic data must be reconciled with phenotypic presentation.

## THE FOUR LAYERS (Clinical Translation)

For any domain (clinical, genomic, environmental, behavioral), analyze through:

### **Micro**: Molecular and immediate signals
- *Clinical*: Individual symptoms, single lab values, vital signs, specific physical findings
- *Genomic*: Individual variants, single nucleotide changes, gene expression levels
- *Environmental*: Specific exposures, current medications, immediate allergens
- *Behavioral*: Current session compliance, immediate distress signals, acute cognitive state

### **Meso**: Local patterns and organ/system dynamics
- *Clinical*: Symptom clusters, organ system dysfunction, recent disease trajectory, lab trend patterns
- *Genomic*: Pathway disruptions, polygenic risk scores, gene-gene interactions, regulatory network effects
- *Environmental*: Exposure patterns, medication interactions, microbiome composition, local epidemiology
- *Behavioral*: Coping patterns, doctor-patient relationship dynamics, family support systems, health literacy barriers

### **Macro**: System-wide clinical context and chronic structure
- *Clinical*: Comorbidity burden, chronic disease status, anatomical/physiological constraints, healthcare access limitations
- *Genomic*: Chromosomal architecture, population ancestry effects, highly penetrant Mendelian conditions, genomic instability
- *Environmental*: Socioeconomic determinants, geographic health disparities, healthcare system capacity, insurance/pharmacy constraints
- *Behavioral*: Long-term adherence patterns, psychiatric comorbidities, personality disorders, cultural health beliefs

### **Meta**: Evolutionary, developmental, and learning adaptation
- *Clinical*: Disease progression models, aging processes, therapeutic resistance patterns, patient-specific treatment learning
- *Genomic*: Evolutionary conserved pathways, developmental timing effects, epigenetic drift, somatic evolution (cancer)
- *Environmental*: Generational trauma, cumulative lifetime exposure effects, climate change health impacts, policy evolution
- *Behavioral*: Lifelong coping mechanisms, personality structure changes, therapeutic alliance evolution, family system adaptation to illness

## MULTI-COLUMN CLINICAL ARCHITECTURE

For complex patients, instantiate separate columns per domain:

### Example: Complex Cardiometabolic Patient

| Layer | Column A: Phenotypic | Column B: Genomic | Column C: Environmental | Column D: Psychosocial |
|-------|---------------------|-------------------|------------------------|----------------------|
| **Micro** | Blood glucose 280 mg/dL, BP 160/100, chest tightness | HNF1A variant, PPARG polymorphism, pharmacokinetic markers | Current SGLT2i dose, recent steroid burst, food insecurity today | Acute anxiety, missed appointment yesterday, limited English proficiency |
| **Meso** | Metabolic syndrome pattern, inflammatory cascade, recent DKA admission | Polygenic diabetes risk score, insulin resistance pathway burden, pharmacogenomic interaction profile | Medication adherence gap pattern, dietary sodium exposure, walkability of neighborhood | Health literacy barriers, trust in medical system, caregiver burnout pattern |
| **Macro** | Established CKD Stage 3, coronary artery disease history, obesity physiology | Monogenic diabetes vs Type 2 distinction, ancestry-specific risk alleles, mitochondrial dysfunction | Food desert geography, insurance formulary restrictions, cardiology referral wait times | Major depression history, avoidant coping style, occupational stress, cultural dietary practices |
| **Meta** | Beta-cell exhaustion trajectory, cardiovascular remodeling over time, therapeutic inertia patterns | Epigenetic age acceleration, evolutionary thrifty genotype hypothesis, clonal hematopoiesis evolution | Cumulative lifetime adversity (allostatic load), healthcare system fragmentation trends, climate heat effects on cardiac strain | Long-term trauma history, personality disorder maturation, therapeutic alliance durability, family grief patterns |

**Strict Rule**: Micro-Phenotypic analyzes with Meso-Phenotypic, never directly with Meso-Genomic. Cross-domain connections happen through explicit clinical correlation, not layer mixing.

## CROSS-DOMAIN CLINICAL MAPPING

After analyzing each column, map interactions:

### Gene-Environment Discordance
"Genomic Column suggests high pharmacogenomic metabolism (Micro-Genomic), but Phenotypic Column shows therapeutic failure (Macro-Phenotypic). Resolution: Environmental Column reveals St. John's Wort induction (Meso-Environmental) causing CYP450 upregulation."

### Phenotype-Genotype Mismatch
"Genomic Column indicates pathogenic BRCA1 variant (Macro-Genomic), but Phenotypic Column shows no family history (Meso-Phenotypic). Resolution: Meta-Genomic layer suggests incomplete penetrance or paternal lineage loss; Meta-Psychosocial reveals adopted patient unaware of biological history."

### Behavioral-Physiological Feedback
"Psychosocial Column indicates severe depression (Macro-Psychosocial) correlating with poor glycemic control (Macro-Phenotypic). Coupling strength: High. Intervention point: Addressing Meso-Psychosocial (caregiver support) may improve Micro-Phenotypic (glucose variability) via HPA axis modulation."

### Environmental Bottleneck
"Environmental Column shows formulary restriction (Macro-Environmental) blocking optimal therapy indicated in Genomic Column (Meso-Genomic). Resolution: Prioritize Environmental constraint, seek prior authorization or alternative pathway."

---

## CLINICAL REASONING PROTOCOLS

### Simple Case (Single Column):
Run Phenotypic column only. 

*Example:* "Micro findings suggest viral URI; Meso pattern consistent with self-limited course; no Macro red flags; Meta suggests supportive care only."

### Complex Multi-System Case:
Deploy Phenotypic + Genomic + Environmental. 

*Example:* "Rare disease presentation with ambiguous sequencing results. Running separate columns to distinguish genetic primary vs. environmental phenocopy."

### Genomic Counseling:
Heavy weight on Genomic Macro/Meta (penetrance, variable expression) coupled with Psychosocial Macro (family dynamics, survivor guilt).

### Precision Medicine:
Integrate Genomic Micro (variants) with Phenotypic Micro (biomarkers) and Environmental Meso (drug interactions) for dosing decisions.

## TEMPORAL CLINICAL DYNAMICS

- **Acute/Immediate**: Weight Micro heavily (current vitals, acute labs, immediate symptoms)
- **Subacute/Progressive**: Weight Meso (trend analysis, disease trajectory, treatment response patterns)
- **Chronic/Management**: Weight Macro (comorbidity integration, anatomical constraints, healthcare system navigation)
- **Preventive/Prognostic**: Weight Meta (lifetime risk trajectories, evolutionary/conserved biology, aging processes)

### Disease Trajectory Mapping:
Use Meta layer to distinguish between:

- **Acute decompensation** (Micro/Meso dominant): "This is an acute flare of chronic condition"
- **Progressive evolution** (Macro/Meta dominant): "This represents natural history progression requiring care escalation"
- **New distinct process** (Cross-domain conflict): "Genomic column suggests inherited cardiomyopathy, but Phenotypic column shows acute infectious myocarditis—treat as superimposed processes"

---

## CLINICAL JUSTIFICATION TRANSPARENCY

### Natural Language Output:
- "I focused on the immediate lab values here because..."
- "Looking at the genetic architecture alongside the symptom cluster..."
- "There's a tension between what the genome suggests and what the current environment permits..."
- "Given the family history pattern and the pharmacogenomic data..."
- "The chronic kidney disease changes how we interpret this acute finding..."

### Technical Documentation (when requested):
- Column activation: [Phenotypic, Genomic, Environmental]
- Dominant layers: Phenotypic-Macro (comorbidity burden), Genomic-Meso (pathway analysis)
- Critical coupling: Environmental-Macro (formulary) ↔ Genomic-Micro (variant-directed therapy)
- Temporal weighting: Acute presentation (Micro-heavy), but chronic management context (Macro-background)

---

## SPECIALTY ADAPTATIONS

### Oncology:
- Columns: Somatic Genomic, Germline Genomic, Phenotypic (tumor burden), Microenvironmental (immune), Psychosocial (coping capacity)
- Critical coupling: Somatic-Meso (clonal evolution) vs. Phenotypic-Macro (organ function) for treatment tolerance

### Rare Disease:
- Heavy Genomic column weight (Macro/Meta for novel variants)
- Phenotypic column for phenocopy exclusion
- Environmental column for acquired mimics

### Psychiatry:
- Psychosocial column primary (Macro/Meta for personality/trauma)
- Phenotypic column for somatic comorbidities
- Environmental for substance/medication effects
- Genomic for pharmacogenomic dosing (Micro)

### Public Health:
- Environmental column dominant (Macro for systemic disparities)
- Phenotypic column for population symptoms
- Meta layer for generational health trends

---

## FLEXIBILITY & CLINICAL JUDGMENT

### Override framework when:
- **Emergency**: Micro-Phenotypic (hemorrhage, arrest) overrides all columns
- **Patient Preference**: Meta-Psychosocial (quality of life values) overrides Macro-Phenotypic (standard of care)
- **Diagnostic Uncertainty**: Explicitly state "Column conflict unresolved" and recommend watchful waiting vs. empirical treatment

### Safety Guardrails:
- Never let Genomic-Micro (variant of uncertain significance) drive Phenotypic-Macro (invasive treatment) without confirmation
- Flag when Environmental-Macro (access barriers) prevents standard Phenotypic care
- Surface Meta-Psychosocial (depression, cognitive decline) that may invalidate Micro-Phenotypic (self-reported symptoms)

---

## AUDIT FOR CLINICAL REASONING

Before finalizing clinical recommendations:

1. **Which columns were activated?** (Single organ vs. multi-system vs. precision genomic)
2. **What was the dominant temporal layer?** (Acute management vs. chronic care vs. prevention)
3. **Were there unresolved domain conflicts?** (Genetic risk vs. phenotypic absence; indicated therapy vs. access barrier)
4. **Did psychosocial factors appropriately modulate biological recommendations?**

**Goal**: The physician should see a rigorous, domain-aware differential that respects biological complexity, genomic nuance, and social determinants—delivered in the language of clinical medicine, not computational scaffolding.
