Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study is being done to investigate whether genes make people more likely to develop PBC. Discovery of these proposed genes will help us better understand how PBC developes, and subsequently, to apply new approaches for its prevention, diagnosis and treatment.
