The Rare Disease Search Engine is specialized search engine using Google's co-op program combined with a narrowed field of search to eliminate useless results that would normally complicate one's search for needed information.

To Search: simply begin typing in the name of the condition you wish to find. Results matching the partial name will be returned. The results will search through the name, abbreviation and alternate names of all conditions we have in our database. The results that are returned will be links to search results of a narrowed, filtered web search of only those sites that offer reliable, focused information on rare diseases. Hovering over the condition name will display a ist of alternate names on file.
