CHIP Clonal Hematopoiesis Agent

The CHIP Clonal Hematopoiesis Agent provides comprehensive detection and risk stratification of clonal hematopoiesis of indeterminate potential (CHIP). It identifies clonal mutations in blood cells, assesses risk of progression to myeloid malignancy, and predicts cardiovascular disease risk, integrating with the CHIC machine learning framework for CBC-based screening.

When to Use This Skill

• When detecting CHIP mutations from blood sequencing data.
• For stratifying risk of progression to MDS/​AML.
• To assess CHIP-associated cardiovascular disease risk.
• When filtering CHIP variants from tumor liquid biopsy.
• For population-level CHIP screening and research.

Core Capabilities

1. CHIP Detection: Identify clonal mutations with VAF >2%.

2. Risk Stratification: Predict myeloid malignancy progression risk.

3. CVD Risk Assessment: Estimate cardiovascular disease risk.

4. CCUS Classification: Distinguish CHIP from CCUS/​MDS.

5. Clone Size Tracking: Monitor clonal evolution over time.

6. ctDNA Filtering: Remove CHIP from tumor ctDNA analysis.

CHIP-Associated Genes

Risk Categories

Workflow

1. Input: Blood sequencing (WES/​panel), CBC data, clinical history.

2. Variant Detection: Call somatic variants with VAF filtering.

3. CHIP Classification: Identify CHIP-defining mutations.

4. Risk Scoring: Calculate malignancy and CVD risk scores.

5. Longitudinal Analysis: Track clone dynamics if serial samples.

6. Clinical Integration: Generate management recommendations.

7. Output: CHIP status, risk scores, monitoring plan.

Example Usage

User: "Analyze this patient's blood sequencing for CHIP and calculate their risk of progression and cardiovascular events."

CHIP vs ctDNA Filtering

Special Considerations

1. VAF Threshold: Use 2% for CHIP definition
2. Germline Filtering: Exclude germline variants
3. Age Context: Prevalence increases with age
4. Therapy History: Consider treatment-related clones
5. Serial Monitoring: Track clone dynamics
