Aceruloplasminemia with Abnormal Compound Heterozygous Mutations Developed Neurological Dysfunction during Phlebotomy Therapy.

Aceruloplasminemia is an autosomal recessive inherited disorder caused by ceruloplasmin gene mutations. The loss of ferroxidase activity of ceruloplasmin due to gene mutations causes a disturbance in cellular iron transport. We herein describe a patient with aceruloplasminemia, who presented with diabetes mellitus that was treated by insulin injections, liver hemosiderosis treated by phlebotomy therapy, and neurological impairment. A genetic analysis of the ceruloplasmin gene revealed novel compound heterozygous mutations of c.1286_1290insTATAC in exon 7 and c.2185delC in exon 12. This abnormal compound heterozygote had typical clinical features similar to those observed in aceruloplasminemia patients with other gene mutations.
