A congenital hypochromic microcytic anaemia (OMIM:206200) characterised by very low mean corpuscular erythrocyte volume, low transferrin saturation, abnormal iron absorption and no haematologic improvement following treatment with oral iron, abnormal iron utilisation with a sluggish, incomplete response to parenteral iron, and normal urinary levels of hepcidin. 

Molecular pathology Defects in TMPRSS6, which encodes a liver specific serine protease, cause iron-refractory iron deficiency anaemia–IRIDA.

Synonyms Anaemia—hypochromic microcytic—with defect in iron metabolism, hereditary iron-handling disorder, hypochromic microcytic anaemia with defect in iron metabolism, IRIDA, iron handling disorder—hereditary, pseudo-iron-deficiency anaemia
