HumanDNAVisualizer - Project Summary

What Has Been Created

A complete, production-ready genomic visualization and analysis platform with:

Backend Services (Java 17 + Spring Boot 3)

DNA Integrator Service (backend/dna-integrator/)

  • REST API for uploading VCF, FHIR, and CSV data
  • Parsers for genomic variants, health records, and lifestyle data
  • PostgreSQL integration for data persistence
  • Libraries used: Spring Boot, HAPI FHIR, BioJava, Apache Commons CSV
  • All libraries: Apache License 2.0 / MIT / LGPL (open-source)

AI/ML Services (Python 3.10 + FastAPI)

Trait Predictor (ai-model/)

  • PyTorch neural network for trait predictions
  • Predicts: diabetes risk, cardiovascular risk, cognitive function, vitamin metabolism
  • Processes genomic, phenotypic, and environmental data
  • Libraries: FastAPI, PyTorch, NumPy, Pandas, BioPython (all open-source)

LLM Service (llm-service/)

  • Natural language query interface
  • Personality-tailored responses (strategic, empathetic, creative, analytical, quick)
  • Troubleshooting assistance
  • Libraries: FastAPI, Transformers, PyTorch (all open-source)

Frontend (React 18 + Three.js)

Pages:

  • Home.jsx: Landing page with features overview
  • Analyze.jsx: Data upload and trait prediction interface
  • Explore.jsx: 3D DNA visualization

Components:

  • DataUpload.jsx: File upload with VCF/CSV support
  • TraitDetails.jsx: AI prediction results display
  • LLMChat.jsx: Natural language query interface
  • DNAViewer.jsx: Interactive 3D DNA double helix with Three.js

Libraries:

  • React 18.2.0, Three.js 0.158.0
  • @react-three/fiber 8.15.11, @react-three/drei 9.92.5
  • Axios 1.6.0, Plotly.js 2.27.0
  • DOMPurify 3.0.6, Tailwind CSS 3.3.5
  • All with MIT/Apache licenses

Database (PostgreSQL 15)

Schema (database/postgres/schema.sql)

  • genomic_data: VCF variants storage
  • phenotypic_data: FHIR health records
  • environmental_data: Lifestyle factors
  • user_sessions: Session management
  • annotations: User annotations

Infrastructure

Docker Configuration:

  • docker-compose.yml: Orchestrates all services
  • Individual Dockerfiles for each service
  • PostgreSQL and Redis containers
  • Network isolation and health checks

Configuration Files:

  • .env.example: Environment variables template
  • .gitignore: Git exclusions
  • LICENSE: MIT License with third-party attributions

Documentation
