Anemia in myelodysplastic syndrome with ring sideroblasts

Anemia in myelodysplastic syndrome with ring sideroblasts is a hematologic manifestation of a clonal hematopoietic stem cell neoplasm primarily affecting older adults It is characterized by ineffective erythropoiesis that results in chronic peripheral cytopenia and potential transfusion dependence

It is characterized by ineffective erythropoiesis that results in chronic peripheral cytopenia and potential transfusion dependence Pathophysiologically, the condition is defined by the accumulation of iron within the mitochondria of erythroid precursors, visible on bone marrow evaluation as a collar of perinuclear iron granules encircling at least one-third of the nucleus This subtype is frequently driven by somatic mutations in the RNA splicing machinery gene *SF3B1*, which lead to abnormal mi...

It is characterized by ineffective erythropoiesis that results in chronic peripheral cytopenia and potential transfusion dependence

Pathophysiologically, the condition is defined by the accumulation of iron within the mitochondria of erythroid precursors, visible on bone marrow evaluation as a collar of perinuclear iron granules encircling at least one-third of the nucleus

This subtype is frequently driven by somatic mutations in the RNA splicing machinery gene *SF3B1*, which lead to abnormal mitochondrial iron handling, maturation arrest in late-stage erythroblasts, and a heightened risk of secondary systemic iron overload
