Identifying Genetic Causes of IC/BPS

Recruiting

• Conditions: Interstitial Cystitis; Bladder Pain Syndrome

• Registration Number: NCT00389142
• Lead Sponsor: Boston Children's Hospital

Brief Summary

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, we 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. We are enrolling inviduals with IC/BPS and their family members (family members with and without IC like symptoms). Travel to Boston not required.

Detailed Description

We are trying to identify a genetic cause of interstitial cystitis (IC)/bladder pain syndrome (BPS). We are looking to enroll individuals with a clinical diagnosis of IC/BPS and their family member. We are attempting to determine if there is a connection between symptoms of IC/PBS and changes in specific genes or a pathway of connected genes. We will use several genetic technologies including but not limited to; linkage analysis, genome sequencing, RNAseq and candidate gene studies to try to identify the cause of IC/BPS. Once we identify the cause of IC/BPS we will be able to identify and design more effective treatments for affected individuals. We are looking for families with IC/BPS symptoms to give a DNA sample (from blood/saliva), urine samples, and answer several questionnaires. Travel to Boston NOT necessary.
