Iron-refractory iron deficiency anemia (IRIDA) is a rare autosomal-recessive disorder hallmarked by hypochromic microcytic anemia, low transferrin saturation, and unresponsiveness to oral iron with partial recovery after parenteral iron administration. The disease is caused by mutations in TMPRSS6 (transmembrane protease serine 6) that prevent inactivation of membrane-bound hemojuvelin, an activator of hepcidin transcription. To date, 38 cases have been characterized and reported in European countries and the United States. In this paper, we describe the first case of a Japanese female with IRIDA, who carried a novel mutation (K253E) in the CUB (complement factor C1r/C1s, urchin embryonic growth factor and bone morphogenetic protein 1) domain of the TMPRSS6 gene.
