Diamond–Blackfan anemia
（重定向自Diamond Blackfan syndrome）
Diamond–Blackfan anemia (DBA), also known as Blackfan-Diamond anemia, inherited pure red cell aplasia and as inherited erythroblastopenia, is a congenital erythroid aplasia that usually presents in infancy. DBA causes low red blood cell counts (anemia), without substantially affecting the other blood components (the platelets and the white blood cells), which are usually normal. This is in contrast to Shwachman–Bodian–Diamond syndrome, in which the bone marrow defect results primarily in neutropenia, and Fanconi anemia, where all cell lines are affected resulting in pancytopenia.
