DNA Analyzer

Upload a raw DNA data export from a consumer testing service and get a personalized report of health, trait, drug-response, and ancestry findings — matched against a curated local database of 10,600+ SNPs, with live SNPedia lookups for anything not already cached locally.

Everything runs locally: uploaded files are parsed, matched, and deleted immediately after analysis. Nothing is stored server-side.

Features

• Drag-and-drop upload for raw DNA files (.txt, .csv, .zip)
• Multi-format parser — supports 23andMe, AncestryDNA, MyHeritage, and FamilyTreeDNA raw data exports
• Local SNP database — 10,600+ curated entries across health (9.5k), ancestry (400), trait (550), and drug-response (130) categories, merged from curated research data and SNPedia
• Live SNPedia fallback for SNPs not yet in the local database, with single and batch lookup
• Downloadable HTML report with Chart.js visualizations, generated client-side from your results — shareable as a standalone file
• Results sorted by significance (magnitude) within each category

Stack

• Frontend: Angular (standalone components), served on its own dev server
• Backend: Node.js / Express, with Multer for uploads and csv-parse for file parsing
• Data: Local JSON/JS SNP database + SNPedia API integration

Getting started

npm run install:all   # installs root, backend, and frontend dependencies
npm start              # runs backend and frontend concurrently

This starts the Express API and the Angular dev server together. Open the frontend URL printed in the console and upload a raw DNA export to generate a report.
