Sideroblastic anemias are a diverse group of anemias characterized by the presence of ringed sideroblasts (erythroblasts with perinuclear iron-engorged. Sideroblastic anemia is primarily a laboratory diagnosis, made on the basis of bone-marrow examination with Prussian blue stain. The history. Disease definition. Adult onset autosomal recessive sideroblastic anemia or GLRX5-related sideroblastic anemia is a very rare non-syndromic autosomal.
