| | # OncoScope Cancer Genomics Analysis Model |
| |
|
| | OncoScope is a specialized AI model fine-tuned for cancer genomics analysis and precision oncology. Built on Google's Gemma 3n architecture, this model provides expert-level analysis of cancer mutations, risk assessments, and therapeutic recommendations while maintaining complete privacy through on-device inference. |
| |
|
| | ## Model Details |
| |
|
| | - **Base Model**: Google Gemma 3n 2B E4B Chat IT |
| | - **Parameters**: 6.9B (quantized from fine-tuned model) |
| | - **Architecture**: Gemma3n |
| | - **Quantization**: Q8_0 GGUF format |
| | - **Context Length**: 32,768 tokens |
| | - **Embedding Length**: 2,048 |
| | |
| | ## Key Features |
| | |
| | - **Cancer Mutation Analysis**: Pathogenicity assessment using ACMG/AMP guidelines |
| | - **Risk Stratification**: Hereditary cancer syndrome evaluation |
| | - **Therapeutic Recommendations**: Evidence-based drug target identification |
| | - **Privacy-First**: Designed for on-device inference with Ollama |
| | - **Clinical Guidelines**: Incorporates established medical standards |
| | - **Multi-mutation Analysis**: Complex genomic interaction assessment |
| | |
| | ## Training Data |
| | |
| | The model was fine-tuned on a curated dataset of 5,998 cancer genomics examples from: |
| | - **ClinVar**: Clinical variant database |
| | - **COSMIC Top 50**: Cancer mutation signatures |
| | - **Expert-curated**: Clinical oncology cases |
| | |
| | ## Usage |
| | |
| | ### With Ollama |
| | |
| | 1. **Download the model files**: |
| | - `oncoscope-gemma-3n-merged.Q8_0.gguf` (6.8GB) |
| | - `Modelfile` |
| |
|
| | 2. **Create the model**: |
| | ```bash |
| | ollama create oncoscope -f Modelfile |
| | ``` |
| |
|
| | 3. **Run inference**: |
| | ```bash |
| | ollama run oncoscope "Analyze the clinical significance of BRCA1 c.5266dupC mutation" |
| | ``` |
| |
|
| | ### Example Usage |
| |
|
| | ```bash |
| | ollama run oncoscope "Patient: 45-year-old female with family history of breast cancer. |
| | Mutation: BRCA1 c.68_69delAG (p.Glu23ValfsTer17). |
| | Please provide pathogenicity assessment and recommendations." |
| | ``` |
| |
|
| | **Example Response**: |
| | ```json |
| | { |
| | "mutation_analysis": { |
| | "gene": "BRCA1", |
| | "variant": "c.68_69delAG", |
| | "protein_change": "p.Glu23ValfsTer17", |
| | "pathogenicity": "Pathogenic", |
| | "confidence_score": 0.95, |
| | "acmg_classification": "PVS1, PM2, PP3" |
| | }, |
| | "clinical_significance": { |
| | "cancer_risk": "High", |
| | "associated_cancers": ["Breast", "Ovarian"], |
| | "lifetime_risk": { |
| | "breast_cancer": "55-85%", |
| | "ovarian_cancer": "15-40%" |
| | } |
| | }, |
| | "recommendations": { |
| | "genetic_counseling": "Strongly recommended", |
| | "screening": "Enhanced surveillance starting age 25", |
| | "prevention": "Consider prophylactic surgery", |
| | "family_testing": "Cascade testing recommended" |
| | } |
| | } |
| | ``` |
| |
|
| | ## Model Capabilities |
| |
|
| | - **Pathogenicity Assessment**: ACMG/AMP guideline compliance |
| | - **Risk Calculation**: Quantitative cancer risk estimates |
| | - **Drug Recommendations**: FDA-approved targeted therapies |
| | - **Family History Analysis**: Hereditary pattern recognition |
| | - **Genetic Counseling**: Evidence-based guidance |
| | - **Multi-lingual Support**: Medical terminology in multiple languages |
| |
|
| | ## Limitations |
| |
|
| | - **Medical Disclaimer**: This model is for research and educational purposes only. Always consult qualified healthcare professionals for medical decisions. |
| | - **Training Cutoff**: Knowledge based on training data through early 2024 |
| | - **Quantization**: Some precision loss due to Q8_0 quantization |
| | - **Context Window**: Limited to 4,096 tokens for optimal performance |
| | |
| | ## Technical Specifications |
| | |
| | - **Model Size**: 6.8GB (GGUF Q8_0) |
| | - **Memory Requirements**: 8GB+ RAM recommended |
| | - **Hardware**: CPU inference optimized, GPU acceleration supported |
| | - **Operating Systems**: Cross-platform (macOS, Linux, Windows) |
| |
|
| | ## Performance |
| |
|
| | The model demonstrates expert-level performance on: |
| | - Variant pathogenicity classification (>90% accuracy vs. clinical consensus) |
| | - Cancer risk assessment correlation with established guidelines |
| | - Therapeutic recommendation alignment with FDA approvals |
| | - Response time: 20-40 seconds for complex genomic analysis |
| |
|
| | ## Privacy & Security |
| |
