Pharmacogenomics Agent

The Pharmacogenomics Agent integrates AI and multi-omics data to predict individual drug responses, optimize medication dosing, and minimize adverse events. It implements CPIC guidelines while leveraging deep learning for complex polygenic drug response phenotypes.

When to Use This Skill

• When interpreting pharmacogenomic variants (CYP450, HLA, transporters) for drug selection.
• To predict drug response using transcriptomic and proteomic biomarkers.
• For calculating polygenic risk scores for drug efficacy/toxicity.
• When optimizing doses for narrow therapeutic index drugs.
• To identify drug-drug-gene interactions.

Core Capabilities

1. Variant Interpretation: Translates star allele genotypes (*1/*2) into metabolizer phenotypes and actionable CPIC recommendations.

2. Multi-Omics Response Prediction: Deep learning models (DeepDRA, MOViDA) integrate genomic, transcriptomic, and proteomic features for drug response prediction.

3. Polygenic Risk Scoring: Combines effects of thousands of variants to stratify patients beyond single-gene pharmacogenomics.

4. Adverse Event Prediction: Identifies genetic risk factors for serious adverse reactions (HLA associations, G6PD deficiency).

5. Dose Optimization: AI-guided dosing for warfarin, tacrolimus, fluoropyrimidines, thiopurines, and other PGx-guided drugs.

6. Drug-Drug-Gene Interactions: Detects complex interactions where genetic variants modify drug interaction severity.

CPIC-Guided Genes and Drugs

Workflow

1. Input: Patient genotype data (VCF, genotyping array), medication list, clinical parameters.

2. Star Allele Calling: Translate variants to star alleles using Stargazer or PharmCAT.

3. Phenotype Assignment: Determine metabolizer status (PM, IM, NM, UM) for each gene.

4. Guideline Lookup: Retrieve CPIC/DPWG recommendations for patient's medications.

5. Multi-Omics Prediction: Apply deep learning for complex response phenotypes.

6. Output: Drug-specific recommendations, dose adjustments, alternative medications, interaction alerts.

Example Usage

User: "Interpret this patient's pharmacogenomic panel and provide recommendations for their current medications."

AI Models for Drug Response

Polygenic Drug Response

Beyond single-gene PGx, polygenic scores capture:

• Efficacy polygenic scores: Statin LDL response, antidepressant remission
• Toxicity polygenic scores: Metformin GI intolerance, opioid dependence risk
• Combined scores: Integrating PRS with PGx for personalized prediction

Prerequisites

• Python 3.10+
• PharmCAT or Stargazer for star allele calling
• CPIC/DPWG guideline databases
• Deep learning frameworks (PyTorch)
• Optional: Expression data for multi-omics models
