Sarcoidosis is a disease that can affect any organ of the body. Very small clusters of inflammation or white cells, called granulomas, are seen in the organs affected with sarcoidosis. The lungs are the most common organs involved. These granulomas may clear up on their own, or cause permanent scarring.

 

Causes

The cause of sarcoidosis is unknown, but it is likely that there may be more than one cause.

While we do not know sarcoidosis' cause, other important facts about its development are known.

Sarcoidosis occurs more often in Caucasians of European descent and in African-Americans. About 10 to 40 out of every 100,000 people develop sarcoidosis. It is most common in young people between the ages of 20 and 40. Sarcoidosis is not contagious.

Clinical Trials

Study of Genetic Risk for Sarcoidosis

The purpose of this study is to identify genetic markers associated with the disease sarcoidosis. We are recruiting individuals with sarcoidosis and healthy controls.

Participation involves a one-time visit, at which time the participant will sign an Informed Consent form, fill out a questionnaire, and have a low-volume blood draw.
