Web16 apr. 2024 · Megaloblastic anemia: impairments in DNA synthesis (e.g. folate, B12 deficiency, orotic aciduria) result in abnormal development of the nucleated erythroblasts (RBC precursors) in the marrow. These precursor cells cant make DNA properly, so their division is delayed while cytoplasmic protein synthesis continues unhindered (“nuclear ... WebA characteristic feature of cobalamin de ciency is nuclear-cytoplasm asynchrony in erythroid maturation, whereby maturation of the nucleus is delayed relative to that of the cytoplasm because cobalamin is essential for DNA synthesis 4, 5.

A megaloblast is an unusually large erythroblast that can be associated with vitamin B12 deficiency (caused by pernicious anemia or dietary insufficiency), folic acid deficiency, or both (such anemias are collectively called megaloblastic anemias). This kind of anemia leads to macrocytes (abnormally large red cells) and the condition called macrocytosis. The cause of this cellular gigantism is an impairment in DNA replication that delays nuclear maturation and cell division.
