UCLA Center for Rare Diseases intro video
Rare Diseases are defined as chronic diseases that affect only 0.05% of the population or less. There are over 7000 known rare diseases, and taken together, they affect around 8% of the world’s population.



The California Center for Rare Diseases at UCLA is a collaborative home for physicians, scientists and patients dedicated to improving diagnostics and clinical care, basic understanding, and novel treatments for rare genetic diseases.
The California Center for Diseases is committed to furthering research of rare diseases. The CCRD partners with many UCLA clincians and researchers studying rare diseases. These studies include patient registries, sample collection, and clinical trials. Click to learn more.
A major goal of the Center is to provide additional research testing to solve undigiagnosed genetic disorders. We will use clinical information combined with testing only available through research to solve complex medical cases.
