Rare disease search prototype built on Orphanet data

Find a rare disease

Data via Orphadata
What is this?

This is a working prototype built by Danny Englander, not a comprehensive database. It currently covers a sample of 920 of Orphadata's 10,101 catalogued rare diseases. Not finding something here doesn't mean it isn't real or rare. If you'd like to learn more about how this site was built and why, see the About page.

How this search works
  • As you type, results filter instantly, matching against each disease's name, synonyms, and symptoms.
  • Open Filters to fine-tune by body system, inheritance pattern, age of onset, or rarity. Filters combine with your search text and with each other.
  • Active filters show up as removable chips above the results; click a chip's × to drop just that one.
  • Clear all resets both the search box and every filter at once.
  • Results load 20 at a time; use Show more to keep going.

Search by name, synonym, or symptom. Filter by body system or inheritance pattern.
