Congenital sideroblastic anemia of a Saudi child.

Sideroblastic anemia is a heterogeneous group of disorders characterized by the presence of ring sideroblasts in the bone marrow, and has congenital and acquired forms. Congenital sideroblastic anemia is a rare condition, which is mostly X-linked, caused by mutations of delta-aminolevulinic acid synthase 2. We describe one case of congenital sideroblastic anemia, indicating an autosomal recessive inheritance, with its clinico-hematological profile. It is important to recognize this entity early in life as a significant percentage of cases respond to pyridoxine thus avoiding any long-term complications.
