The purpose and goal of the Alpha-1 Research Registry (Registry, or group of patients) will be to obtain uniform, longitudinal (over the course of time), complete and accurate data that can be organized, and made available for the public to query. The collective number of Registry members enables investigators to enroll sufficient subjects to carry out their studies. The community benefits from having more research and potential therapies performed in their disease. Regular updates from patients will give objective data-points to measure the progression of disease.
