Aceruloplasminemia: new clinical, pathophysiological and therapeutic insights

Abstract Aceruloplasminemia is an autosomal recessive disease of iron overload associated with mutation(s) in the ceruloplasmin gene. We report here a new case of aceruloplasminemia in a woman who is a compound heterozygote for two new mutations. Besides this novel genotypic profile, this observation provides new insights on: (i) iron metabolism with normal erythroid repartition, in the absence of serum non-transferrin-bound iron and with an increase of 59 Fe plasma clearance; (ii) hepatic abnormalities associated with the presence of iron-free foci; (iii) the therapeutic management of the disease, chronic subcutaneous infusion of deferrioxamine being remarkably effective at reducing hepatic iron overload.
