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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Arg901*) in the CP gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CP are known to be pathogenic (PMID: 16629161). This variant is present in population databases (rs386134156, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with autosomal recessive aceruloplasminemia (PMID: 11909923). This variant is also known as aa882 CGA;ArgTGA;stop. ClinVar contains an entry for this variant (Variation ID: 42124). For these reasons, this variant has been classified as Pathogenic.
