Establishing a Database of People With Sickle Cell Disease (Comprehensive Sickle Cell Centers Collaborative Data Project [C-Data])

Sickle cell disease (SCD), also known as sickle cell anemia, is an inherited blood disease that can cause intense pain episodes. The purpose of this study is to gather medical information from children and adults with SCD and establish a database so that researchers can contact people to participate in future SCD research studies.
