The Congenital Dyserythropoietic Anemia Registry (CDAR)
The investigators have created and maintain a comprehensive registry for patients with the diagnosis of Congenital Dyserythropoietic Anemia (CDA) in North America. The goal of this registry is to collect long-term confidential data on patients with CDA in the US, Canada, and Mexico and maintain a bio-repository of de-identified patient blood and bone marrow specimens as a tool for the investigation of epidemiology, natural history, biology, and molecular pathogenetic mechanisms of CDA.
• Diagnosis of Congenital Dyserythropoietic Anemia (CDA), whether a genetic mutation is identified or not
• Evidence of congenital anemia/jaundice or a positive family history
• Evidence of ineffective erythropoiesis
• Typical morphological appearance of bone marrow erythroblasts
• All ages (ages 0-99)
