A group of rare heterogeneous inherited or acquired bone marrow disorders, isolated or part of a syndrome, characterized by decreased hemoglobin synthesis, because of defective use of iron (although plasmatic iron levels may be normal or elevated) and the presence of ringed sideroblasts in the bone marrow due to the pathologic iron overload in mitochondria as visualized by Perls' staining. The group encompasses (idiopathic) acquired sideroblastic anemia and constitutional sideroblastic anemias. The latter include syndromic sideroblastic anemias such as Pearson syndrome, mitochondrial mypathy and sideroblastic anemias, x-linked sideroblastic anemia-ataxia, thiamine responsive megaloblastic anemia syndrome and nonsyndromic sideroblastic anemias comprising x-linked and autosomal recessive sideroblastic anemias.
Biomarker and diagnostic research for sideroblastic anemia has been reported in the published literature.
Estimated prevalence: Unknown (Unknown prevalence).
2 clinical trials registered, 1 recruiting. Interventions under study include other interventions and biologic therapy. Pipeline includes 1 NA. Research is primarily sponsored by academic and government institutions.
78 publications have been identified in PubMed for sideroblastic anemia. Research spans Case Report / Case Series (36%), Basic Science / Preclinical (28%), and Review / Meta-Analysis (13%).
