Responsiveness to oral iron and ascorbic acid in a patient with IRIDA.

Mutations in TMPRSS6 gene cause iron-refractory iron deficiency anemia, a rare autosomal recessive disorder characterized by hypochromic microcytic anemia not responsive to oral iron therapy and partially responsive to parenteral iron administration. Here we report a female infant homozygous for a loss of function mutation in TMPRSS6 gene, who responded to oral iron therapy when supplemented with ascorbic acid.
