Diamond-Blackfan anemia

Dr Henry Knipe and Austin Fletcher et al.

Diamond-Blackfan anemia, also known as pure red cell aplasia, is a rare congenital anemia that typically presents in the first few years of life as a normocytic or macrocytic anemia usually only affecting cells of the erythroid lineage 2. However, neutropenia and thrombocytopenia may occasionally be noted 1.  The disorder is also associated with an increased risk of acute myeloid leukemia and osteogenic sarcoma 3 .


Diamond-Blackfan anemia displays an autosomal dominant inheritance with incomplete penetrance 4 . Deletion of ribosomal proteins specifically RPS19 is the cause of Diamond-Blackfan in approximately 25% of patients 2

Congenital malformations are often observed 1:
