This system helps match a set of clinical features (signs, symptoms, and traits) to rare diseases. Getting a list of matching diseases with this system may take a little longer than it does with other systems that simply ask you to type in a list of clinical features. However, because we curate our system by hand and design it to behave like an expert, the list of matching conditions should be more accurate than lists created by systems that scan information from different sources and look for terms that match what is typed in. Thus, our system saves time at the end the process.

To use it, simply tick yes, no or don't know (when asked) for each question. Choosing don't know accurately is very important because our scoring system takes don't know answers into account.

To get started, simply answer yes or no to the questions on this page.
