title: The neurological presentation of ceruloplasmin gene mutations.
abstract: Aceruloplasminemia is an autosomal recessive disorder of iron metabolism resulting from mutations of the ceruloplasmin gene. To better define the neurological phenotype of aceruloplasminemia we reviewed reports of published cases and sought details of unpublished ones. We identified 32 published reports and 1 unpublished case. The age at diagnosis ranged from 16 to 71 years with a mean of 51. For the 28 homozygous cases the most common presentation was with cognitive impairment (12/28, 42%) accompanied by craniofacial dyskinesia (8/28, 28%), cerebellar ataxia (13/28, 46%) and retinal degeneration (21/28, 75%). Four heterozygotes presented with cerebellar signs or tremor, whilst 1 had chorea-athetosis. There were no genotype-phenotype associations, but homozygotes tended to have severer disease.
