Genes affected
CP (HGNC:2295): (ceruloplasmin) The protein encoded by this gene is a metalloprotein that binds most of the copper in plasma and is involved in the peroxidation of Fe(II)transferrin to Fe(III) transferrin. Mutations in this gene cause aceruloplasminemia, which results in iron accumulation and tissue damage, and is associated with diabetes and neurologic abnormalities. Two transcript variants, one protein-coding and the other not protein-coding, have been found for this gene. [provided by RefSeq, Feb 2012]

Neurodegeneration with brain iron accumulation Pathogenic:1
Likely pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpApr 22, 2024Variant summary: CP c.656T>A (p.Val219Glu) results in a non-conservative amino acid change located in the Multicopper oxidase, second cupredoxin domain (IPR001117) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 1.6e-05 in 251114 control chromosomes. c.656T>A has been reported in the literature in multiple individuals affected with Neurodegeneration With Brain Iron Accumulation (Lobbes_2022). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 35585918). ClinVar contains an entry for this variant (Variation ID: 128844). Based on the evidence outlined above, the variant was classified as likely pathogenic. -
