Iron-refractory iron deficiency anemia
Definition:
Iron-refractory iron deficiency anemia (IRIDA) is a rare autosomal recessive disorder characterized by hypochromic microcytic anaemia, low transferrin saturation and high levels of the iron-regulated hormone hepcidin. The disease is caused by mutations in TMPRSS6, which encodes a type II transmembrane serine protease that regulates the expression of the hepcidin.
