Diamond-Blackfan anemia is a rare inherited bone marrow failure syndrome primarily presenting in early infancy or childhood

Diamond-Blackfan anemia is a rare inherited bone marrow failure syndrome primarily presenting in early infancy or childhood It is characterized by pure red cell aplasia, presenting as a profound macrocytic or normochromic anemia with reticulocytopenia and a marked deficiency of erythroid precursors despite an otherwise normocellular bone marrow Up to half of affected individuals demonstrate associated physical anomalies, such as craniofacial, upper limb, cardiac, or urogenital malformations, as ...

It is characterized by pure red cell aplasia, presenting as a profound macrocytic or normochromic anemia with reticulocytopenia and a marked deficiency of erythroid precursors despite an otherwise normocellular bone marrow Up to half of affected individuals demonstrate associated physical anomalies, such as craniofacial, upper limb, cardiac, or urogenital malformations, as well as an increased predisposition to myelodysplastic syndrome, acute myeloid leukemia, and solid tumors

Pathophysiologically, the condition is classified as a ribosomopathy driven predominantly by heterozygous pathogenic variants in ribosomal protein genes, leading to impaired ribosome biogenesis and pro-apoptotic stress during erythropoiesis
