About this study

Chronic cholestatic liver diseases, such as Primary Biliary Cirrhosis (PBC) and Primary Sclerosing Cholangitis (PSC), are progressive liver disorders of unknown cause. Current evidence suggests that genes, the genetic material we inherit from our parents, in combination with environmental factors, likely play an important role in the development of PBC or PSC.

This study is being done to investigate whether genes make people more likely to develop PBC or PSC. Discovery of these genes will help us to understand better how PBC or PSC develops and subsequently, to apply new approaches for its prevention, diagnosis, and treatment.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
