name: tooluniverse-precision-medicine-stratification
description: Comprehensive patient stratification for precision medicine by integrating genomic, clinical, and therapeutic data. Given a disease/condition, genomic data (germline variants, somatic mutations, expression), and optional clinical parameters, performs multi-phase analysis across 9 phases covering disease disambiguation, genetic risk assessment, disease-specific molecular stratification, pharmacogenomic profiling, comorbidity/DDI risk, pathway analysis, clinical evidence and guideline mapping, clinical trial matching, and integrated outcome prediction. Generates a quantitative Precision Medicine Risk Score (0-100) with risk tier assignment (Low/Intermediate/High/Very High), treatment algorithm (1st/2nd/3rd line), pharmacogenomic guidance, clinical trial matches, and monitoring plan. Use when clinicians ask about patient risk stratification, treatment selection, prognosis prediction, or personalized therapeutic strategy across cancer, metabolic, cardiovascular, neurological, or rare diseases.

# Precision Medicine Patient Stratification

Transform patient genomic and clinical profiles into actionable risk stratification, treatment recommendations, and personalized therapeutic strategies. Integrates germline genetics, somatic alterations, pharmacogenomics, pathway biology, and clinical evidence to produce a quantitative risk score with tiered management recommendations.

**KEY PRINCIPLES**:
1. **Report-first approach** - Create report file FIRST, then populate progressively
2. **Disease-specific logic** - Cancer vs metabolic vs rare disease pipelines diverge at Phase 2
3. **Multi-level integration** - Germline + somatic + expression + clinical data layers
4. **Evidence-graded** - Every finding has an evidence tier (T1-T4)
5. **Quantitative output** - Precision Medicine Risk Score (0-100) with transparent components
6. **Pharmacogenomic guidance** - Drug selection AND dosing recommendations
7. **Guideline-concordant** - Reference NCCN, ACC/AHA, ADA, and other guidelines
8. **Source-referenced** - Every statement cites the tool/database source
9. **Completeness checklist** - Mandatory section showing data availability and analysis coverage
10. **English-first queries** - Always use English terms in tool calls. Respond in user's language

## When to Use

Apply when user asks:
- "Stratify this breast cancer patient: ER+/HER2-, BRCA1 mutation, stage II"
- "What is the risk profile for this diabetes patient with HbA1c 8.5 and CYP2C19 poor metabolizer?"
- "NSCLC patient with EGFR L858R, stage IV, TMB 25 - treatment strategy?"
- "Predict prognosis and recommend treatment for this cardiovascular patient"
- "Patient has Marfan syndrome with FBN1 mutation - risk stratification"
- "Alzheimer's risk assessment: APOE e4/e4, family history positive"
- "Personalized treatment plan for type 2 diabetes with genetic risk factors"
- "Which therapy is best for this patient's molecular profile?"

**NOT for** (use other skills instead):
- Single variant interpretation -> Use `tooluniverse-variant-interpretation` or `tooluniverse-cancer-variant-interpretation`
- Immunotherapy-specific prediction -> Use `tooluniverse-immunotherapy-response-prediction`
- Drug safety profiling only -> Use `tooluniverse-adverse-event-detection`
- Target validation -> Use `tooluniverse-drug-target-validation`
- Clinical trial search only -> Use `tooluniverse-clinical-trial-matching`
- Drug-drug interaction analysis only -> Use `tooluniverse-drug-drug-interaction`
- PRS calculation only -> Use `tooluniverse-polygenic-risk-score`

## Phase 1: Disease Disambiguation & Profile Standardization

### Step 1.1: Resolve Disease to EFO ID

```python
# Get disease EFO ID
result = tu.tools.OpenTargets_get_disease_id_description_by_name(diseaseName='breast cancer')
# -> {data: {search: {hits: [{id: 'EFO_0000305', name: 'breast carcinoma', description: '...'}]}}}
efo_id = result['data']['search']['hits'][0]['id']
```

**Common Disease EFO IDs** (for reference):

| Disease | EFO ID | Category |
|---------|--------|----------|
| Breast carcinoma | EFO_0000305 | CANCER |
| Non-small cell lung carcinoma | EFO_0003060 | CANCER |
| Colorectal cancer | EFO_0000365 | CANCER |
| Melanoma | EFO_0000756 | CANCER |

| Type 2 diabetes | EFO_0001360 | METABOLIC |
| Coronary artery disease | EFO_0001645 | CVD |
| Atrial fibrillation | EFO_0000275 | CVD |
| Alzheimer disease | MONDO_0004975 | NEUROLOGICAL |
| Parkinson disease | EFO_0002508 | NEUROLOGICAL |
| Rheumatoid arthritis | EFO_0000685 | AUTOIMMUNE |
| Marfan syndrome | Orphanet_558 | RARE |
| Cystic fibrosis | EFO_0000508 | RARE |

### Step 1.2: Classify Disease Type

Based on disease name and EFO ID, classify into: CANCER, METABOLIC, CVD, NEUROLOGICAL, RARE, AUTOIMMUNE. This determines the Phase 3 routing.

### Step 1.3: Parse Genomic Data

Parse each variant/gene into structured format:
```
"BRCA1 c.68_69delAG" -> {gene: "BRCA1", variant: "c.68_69delAG", type: "frameshift"}
"EGFR L858R" -> {gene: "EGFR", variant: "L858R", type: "missense"}
"CYP2C19 *2/*2" -> {gene: "CYP2C19", genotype: "*2/*2", metabolizer_status: "poor"}
"APOE e4/e4" -> {gene: "APOE", genotype: "e4/e4", risk_allele: "e4"}
```

### Step 1.4: Resolve Gene IDs

```python
# For each gene in profile
result = tu.tools.MyGene_query_genes(query='BRCA1')
# -> hits[0]: {_id: '672', symbol: 'BRCA1', ensembl: {gene: 'ENSG00000012048'}}
ensembl_id = result['hits'][0]['ensembl']['gene']
entrez_id = result['hits'][0]['_id']
```

**Critical Gene IDs** (pre-resolved):

| Gene | Ensembl ID | Entrez ID | Category |
|------|-----------|-----------|----------|
| BRCA1 | ENSG00000012048 | 672 | Cancer predisposition |
| BRCA2 | ENSG00000139618 | 675 | Cancer predisposition |
| TP53 | ENSG00000141510 | 7157 | Tumor suppressor |

| CFTR | ENSG00000001626 | 1080 | Cystic fibrosis |

---

## Phase 2: Genetic Risk Assessment

### Step 2.1: Germline Variant Pathogenicity

For each germline variant provided:

```python
# Search ClinVar for variant pathogenicity
result = tu.tools.clinvar_search_variants(gene='BRCA1', significance='pathogenic', limit=50)
# Check if patient's specific variant is in ClinVar

# For rsID variants, get VEP annotation
result = tu.tools.EnsemblVEP_annotate_rsid(variant_id='rs80357906')
# Returns SIFT, PolyPhen predictions, consequence type

# For HGVS variants
result = tu.tools.EnsemblVEP_annotate_hgvs(hgvs_notation='ENST00000357654.9:c.5266dupC', species='homo_sapiens')
```

**Pathogenicity Classification** (ACMG-aligned):

| Classification | ClinVar Term | Risk Score Points |
|---------------|-------------|-------------------|
| Pathogenic | Pathogenic | 25 (molecular component) |
| Likely pathogenic | Likely pathogenic | 20 |
| VUS | Uncertain significance | 10 (conservative) |
| Likely benign | Likely benign | 2 |
| Benign | Benign | 0 |

### Step 2.2: Gene-Disease Association Strength

```python
# Get genetic evidence for gene-disease pair
result = tu.tools.OpenTargets_target_disease_evidence(
    ensemblId='ENSG00000012048',  # BRCA1
    efoId='EFO_0000305',         # breast cancer
    size=20
)
# Returns evidence items with scores
```

### Step 2.3: GWAS-Based Polygenic Risk

```python
# Search GWAS associations for disease
result = tu.tools.gwas_get_associations_for_trait(trait='breast cancer')
# Returns associated SNPs with effect sizes

# Search GWAS studies via OpenTargets
result = tu.tools.OpenTargets_search_gwas_studies_by_disease(
    diseaseIds=['EFO_0000305'], size=25
)

# For specific genes, check GWAS hits
result = tu.tools.GWAS_search_associations_by_gene(gene_name='BRCA1')
```

**PRS Estimation** (from available GWAS data):

| PRS Percentile | Risk Category | Score Points (0-35) |
|---------------|--------------|---------------------|
| >95th percentile | Very high genetic risk | 35 |
| 90-95th | High genetic risk | 30 |
| 75-90th | Elevated genetic risk | 25 |
| 50-75th | Average-high | 18 |
| 25-50th | Average-low | 12 |
| 10-25th | Below average | 8 |
| <10th | Low genetic risk | 5 |

**Note**: With user-provided variants only (not full genotype), estimate approximate PRS by counting known risk alleles and their effect sizes from GWAS catalog. Flag as "estimated - full genotyping recommended for precise PRS."

### Step 2.4: Population Frequency

```python
# Check variant frequency in gnomAD
result = tu.tools.gnomad_get_variant(variant_id='1-55505647-G-T')
# Returns allele frequency across populations
```

### Step 2.5: Gene Constraint

```python
# Gene intolerance to loss of function
result = tu.tools.gnomad_get_gene_constraints(gene_symbol='BRCA1')
# Returns pLI, LOEUF scores - high pLI/low LOEUF = haploinsufficiency
```

**Genetic Risk Score Component** (0-35 points):

Combine pathogenicity + gene-disease association + PRS:
- Pathogenic variant in disease gene: 25+ points
- Strong GWAS associations (multiple risk alleles): up to 35 points
- VUS in relevant gene: 10-15 points
- No known pathogenic variants but some risk alleles: 5-15 points

#### Step 3C.1: Molecular Subtyping

```python
# Get somatic mutation landscape from cBioPortal
result = tu.tools.cBioPortal_get_mutations(
    study_id='brca_tcga_pub',  # breast cancer TCGA
    gene_list='BRCA1 BRCA2 TP53 PIK3CA ESR1 ERBB2'  # STRING, not array
)
# Returns mutation frequencies, types

# Check cancer prognostic markers
result = tu.tools.HPA_get_cancer_prognostics_by_gene(gene_name='ESR1')
# Returns prognostic data for breast cancer
```

**Cancer-Specific Subtype Definitions**:

| Cancer | Subtype System | Key Markers | High-Risk Features |
|--------|---------------|-------------|-------------------|
| Breast | Luminal A/B, HER2+, TNBC | ER, PR, HER2, Ki67 | TNBC, high Ki67, TP53 mut |
| NSCLC | Adenocarcinoma, squamous | EGFR, ALK, ROS1, KRAS, PD-L1 | KRAS G12C, no driver = chemoIO |
| CRC | MSI-H vs MSS, CMS1-4 | KRAS, BRAF, MSI, CMS | BRAF V600E, MSS |
| Melanoma | BRAF-mut, NRAS-mut, wild-type | BRAF, NRAS, KIT, NF1 | NRAS, uveal |
| Prostate | Luminal vs basal, BRCA status | AR, BRCA1/2, SPOP, TMPRSS2:ERG | BRCA2, neuroendocrine |

#### Step 3C.2: TMB/MSI/HRD Assessment

If TMB provided:
```python
# Check FDA TMB-H approvals
result = tu.tools.fda_pharmacogenomic_biomarkers(drug_name='pembrolizumab', limit=100)
# Look for "Tumor Mutational Burden" in Biomarker field
```

| Biomarker | High-Risk Threshold | Clinical Significance |
|-----------|-------------------|----------------------|
| TMB | >= 10 mut/Mb (FDA cutoff) | Pembrolizumab eligible (tissue-agnostic) |
| MSI-H | MSI-high or dMMR | Pembrolizumab/nivolumab eligible |
| HRD | HRD-positive | PARP inhibitor eligible |

#### Step 3C.3: Prognostic Stratification

Combine stage + molecular features:

| Stage | Low-Risk Molecular | High-Risk Molecular | Score (0-30 clinical) |
|-------|-------------------|--------------------|-----------------------|
| I | Favorable subtype | Unfavorable subtype | 5-10 |
| II | Favorable subtype | Unfavorable subtype | 10-18 |
| III | Any | Any | 18-25 |
| IV | Any | Any | 25-30 |

### METABOLIC PATH (Phase 3M)

#### Step 3M.1: Clinical Risk Integration

```python
# Check genetic risk factors for T2D
result = tu.tools.GWAS_search_associations_by_gene(gene_name='TCF7L2')
# TCF7L2 is strongest T2D risk gene

# Check monogenic diabetes genes
result = tu.tools.OpenTargets_target_disease_evidence(
    ensemblId='ENSG00000148737',  # TCF7L2
    efoId='EFO_0001360',         # T2D
    size=20
)
```

**T2D Stratification**:

| Complications | None | Microalbuminuria | Retinopathy, neuropathy | 0-20 |
| Duration | <5 years | 5-15 years | >15 years | 0-10 |

### CVD PATH (Phase 3V)

```python

| Family hx premature CVD | 10 |
| Lipoprotein(a) elevated | 8 |
| Multiple GWAS risk alleles | 5-15 |

### RARE DISEASE PATH (Phase 3R)

```python
# Check causal variant in disease gene
result = tu.tools.clinvar_search_variants(gene='FBN1', significance='pathogenic', limit=50)
# Marfan syndrome - FBN1 pathogenic variants

# Genotype-phenotype correlation
result = tu.tools.UniProt_get_disease_variants_by_accession(accession='P35555')  # FBN1 UniProt
# Known disease variants and their phenotypes
```

**Rare Disease Risk Assessment**:

result = tu.tools.fda_pharmacogenomic_biomarkers(drug_name='clopidogrel', limit=50)
# CYP2C19 poor metabolizer -> reduced clopidogrel efficacy

# PharmGKB dosing guidelines
result = tu.tools.PharmGKB_get_dosing_guidelines(query='CYP2C19')
# CPIC dosing guidelines
```

**Key Pharmacogenes and Clinical Impact**:

### Step 4.2: Treatment-Specific PGx

```python
# For the specific disease, identify relevant drugs and check PGx
# Example: breast cancer -> tamoxifen -> CYP2D6
result = tu.tools.PharmGKB_get_drug_details(query='tamoxifen')
# Returns PGx annotations for tamoxifen

# Get FDA PGx biomarkers for disease area
result = tu.tools.fda_pharmacogenomic_biomarkers(biomarker='CYP2D6', limit=100)
# All drugs with CYP2D6 PGx in FDA labels
```

### Step 4.3: Drug Target Variants

```python
# Check if patient has variants in drug targets
result = tu.tools.PharmGKB_search_variants(query='VKORC1')
# VKORC1 variants affecting warfarin response
```

**Pharmacogenomic Risk Score** (0-10 points):
- Poor metabolizer for treatment-relevant CYP: 8-10 points
- Intermediate metabolizer: 4-5 points
- High-risk HLA allele: 8-10 points
- Drug target variant: 3-5 points
- Normal metabolizer, no actionable PGx: 0 points

)

# FDA DDI data
result = tu.tools.FDA_get_drug_interactions_by_drug_name(drug_name='metformin', limit=5)
```

### Step 5.3: PGx-Amplified DDI Risk

If patient is a CYP2D6 poor metabolizer AND taking a CYP2D6 inhibitor -> compounded risk.

| Interaction Type | Risk Level | Management |
|-----------------|-----------|------------|
| PGx PM + CYP inhibitor | Very high | Alternative drug or dose reduction |

#### Score Components

**Genetic Risk Component** (0-35 points):

| Scenario | Points |
|----------|--------|
| Pathogenic variant in high-penetrance disease gene (BRCA1, LDLR, FBN1) | 30-35 |
| Multiple moderate-risk variants (GWAS hits + moderate penetrance) | 20-28 |

| Single moderate-risk variant | 12-18 |
| VUS in relevant gene | 8-12 |
| Average PRS, no pathogenic variants | 5-10 |
| Low genetic risk (low PRS, no risk alleles) | 0-5 |

**Clinical Risk Component** (0-30 points):

| 25-49 | **INTERMEDIATE** | Standard treatment, guideline-based care, PGx-guided dosing |
| 0-24 | **LOW** | Surveillance, prevention, risk factor modification |

### Treatment Algorithm

Based on disease type + risk tier + molecular profile + PGx:

#### Cancer Treatment Algorithm

```
IF actionable mutation present:
  1st line: Targeted therapy (e.g., EGFR TKI, BRAF inhibitor, PARP inhibitor)
  2nd line: Immunotherapy (if TMB-H or MSI-H) OR chemotherapy
  3rd line: Clinical trial OR alternative targeted therapy

IF no actionable mutation:
  IF TMB-H or MSI-H:
    1st line: Immunotherapy (pembrolizumab)
    2nd line: Chemotherapy
  ELSE:
    1st line: Standard chemotherapy (disease-specific)
    2nd line: Consider clinical trials

PGx adjustments:
  - DPYD deficient -> AVOID fluoropyrimidines or reduce dose 50%
  - UGT1A1 *28/*28 -> Reduce irinotecan dose
  - CYP2D6 PM + tamoxifen -> Switch to aromatase inhibitor
```

#### Metabolic/CVD Treatment Algorithm

```
IF monogenic form (MODY, FH):
  Disease-specific therapy (e.g., sulfonylureas for HNF1A-MODY, PCSK9i for FH)

IF polygenic risk:
  Standard guidelines (ADA, ACC/AHA)
  PGx-guided drug selection:
    - CYP2C19 PM -> Alternative to clopidogrel (ticagrelor, prasugrel)
    - SLCO1B1 *5 -> Lower statin dose or alternative statin
    - VKORC1 variant -> Warfarin dose adjustment or DOAC
```

### Monitoring Plan

| Component | Frequency | Method |
|-----------|-----------|--------|
| Molecular biomarkers | Per guideline | Liquid biopsy, tissue biopsy |
| Clinical markers | 3-6 months | Labs, imaging |
| PGx-guided drug levels | As needed | TDM |
| Disease progression | Per stage/risk | Imaging, biomarkers |
| Comorbidity screening | Annually | Labs, risk calculators |
