Brief Summary:

Interstitial cystitis (IC), also called painful bladder syndrome (PBS), or chronic pelvic pain syndrome(CPPS) 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, we are collecting genetic material and medical information from families in North America in an attempt to identify genetic factors that may cause IC/PBS/CPPS. We are enrolling families and individuals with IC/PBS/CPPS and their family members (both family members with and without IC like symptoms).


Condition or disease
Interstitial Cystitis Painful Bladder Syndrome Chronic Pelvic Pain Syndrome

Detailed Description:
We are trying to identify a genetic cause of interstitial cystitis (IC)/painful bladder syndrome (PBS)/chronic pelvic pain syndrome (CPPS). By enrolling families we aim to fully describe the symptoms of IC/PBS/CPPS in adults and children. We will attempt to determine if the symptoms of IC/PBS/CPPS match or indicate changes in specific genes. We will use several genetic tests; linkage analysis, whole exome sequencing and candidate gene studies. This will help us decipher the cause of IC and lead us to be able to find better more effective treatments for affected individuals. We are looking for families with IC/PBS/CPPS symptoms to give a DNA sample (from saliva), urine samples and answer 2 questionnaires. Travel to Boston NOT necessary.
