Sideroblastic anemia
MONDO:0015194A 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.
Also known as: anaemia sideroblastic, anemia sideroblastic, sideroblastic anemia

Anemia in kids may be tied to bigger hearts, study finds
Knowledge-focused CompletedThis study explored whether low hemoglobin (anemia) is linked to an enlarged heart (cardiomegaly) in children up to 18 years old. Researchers used chest X-rays and echocardiograms to check for heart enlargement in 56 anemic children. The goal was to better understand how anemia a…
