Overview
X-linked sideroblastic anemia was first described by Cooley (1945), a Detroit pediatrician-hematologist. He considered possible X-linkage in a family in which 19 males in 5 generations were affected, with transmission through unaffected females. In 1946 Rundles and Falls reported 2 families. Slightly enlarged spleens and minor red cell abnormalities without anemia were observed in female carriers. Pyridoxine responsiveness was observed in at least 2 affected members of Rundles and Falls' family In 1961 Byrd and Cooper named the disorder as hereditary iron-loading anemia. In 1983 Peto et al concentrated on iron overload in mild sideroblastic anemia after the death from cardiac siderosis of a middle-aged woman with a very mild form of familial sideroblastic anemia. Cotter et al. (1995) described a previously healthy 81-year-old woman with microcytic sideroblastic anemia. The diagnosis of the X-linked congenital sideroblastic anemia resulted in successful treatment with pyridoxine. She was diagnosed to be heterozygous for a point mutation of the ALAS2 gene. Aivado (2006) reported a family in which a mother and her 2 daughters had sideroblastic anemia that was unresponsive to pyridoxine. It was confirmed by genetic analysis. The disorder was variable in severity and X-chromosome inactivation studies were done. In 1971 Hines found decreased levels of pyridoxal phosphokinase in red cells and livers of patients with pyridoxine-dependent refractory sideroblastic anemia. In 1973A Oki found deficiency of delta-aminolevulinic acid synthetase in the red cells of patients with sideroblastic anemia. In 2001 Levi discovered that iron accumulates in the mitochondria of red cell precursors.
