Identifying Genetic Causes of IC/BPS

Interstitial cystitis (IC), also called Bladder Pain syndrome (BPS) is a common condition with no known cause or cure. Twin studies and family accounts have suggested that the condition may be genetic or passed down (inherited) from one generation to another. In this study, the investigators are collecting genetic material via blood or saliva and medical information from families in North America in an attempt to identify genetic factors that may cause IC/BPS. The investigators are enrolling inviduals with IC/BPS and their family members (family members with and without IC like symptoms). Travel to Boston not required.
