Sideroblastic anemia is a group of blood disorders characterized by an impaired ability of the bone marrow to produce normal red blood cells. In this condition, the iron inside red blood cells is inadequately used to make hemoglobin, despite normal amounts of iron. As a result, iron accumulates in the red blood cells, giving a ringed appearance to the nucleus (ringed sideroblast). The signs and symptoms of this condition may include fatigue, breathing difficulties, weakness, and enlargement of the liver or spleen. There are many potential causes of sideroblastic anemia. Depending on the cause, it can be classified as hereditary (sometimes called congenital), acquired, and idiopathic (cause unknown). The treatment for this condition differs depending on the underlying cause. If acquired, avoidance and or removal of the toxin or drug can lead to recovery. Vitamin B6 (pyridoxine) may be useful in some circumstances. Last updated: 1/26/2017
