Diamond Blackfan Anemia Registry (DBAR)

This registry collects data on patients with Diamond Blackfan Anemia (DBA) — a rare inherited bone marrow failure condition in which the bone marrow doesn't produce enough red blood cells. The registry helps researchers track how DBA develops and responds to treatment over time. You may be eligible if: - You have been diagnosed with Diamond Blackfan Anemia, defined by: macrocytic or normocytic anemia developing in early childhood, low reticulocytes, a bone marrow with a selective deficiency of red cell precursors, and/or a confirmed mutation in a DBA gene You may NOT be eligible if: - You have been identified as having another bone marrow failure syndrome (such as Fanconi anemia, dyskeratosis congenita, or Shwachman Diamond syndrome) Talk to your doctor to see if this trial is right for you.
