Genes affected

ATP7B (HGNC:870): (ATPase copper transporting beta) This gene is a member of the P-type cation transport ATPase family and encodes a protein with several membrane-spanning domains, an ATPase consensus sequence, a hinge domain, a phosphorylation site, and at least 2 putative copper-binding sites. This protein is a monomer, and functions as a copper-transporting ATPase which exports copper out of the cells, such as the efflux of hepatic copper into the bile. Alternate transcriptional splice variants, encoding different isoforms with distinct cellular localizations, have been characterized. Mutations in this gene have been associated with Wilson disease which is characterized by copper accumulation. [provided by RefSeq, Dec 2019]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: The c.3015C>T (p.Asn1005=) in ATP7B gene is a synonymous change that involves a non-conserved nucleotide. 5/5 programs in Alamut predict that this variant does not affect normal splicing, however no functional studies supporting this notion were published at the time of evaluation. The variant is present in the control population dataset of ExAC at frequency of 0.0020 (123/60690 chrs tested), predominantly in individuals of African origin (0.02; 110/5328 chrs, including 2 homozygous occurrences). The observed frequency exceeds the maximum expected allele frequency for a pathogenic variant in this gene (0.0054), suggesting that it is a benign polymorphism. The variant was identified in at least 1 HBOC pt without strong evidence for causality. The variant of interest has not, to our knowledge, been identified in affected individuals via published reports, but is cited as Benign/Likely Benign by reputable database/clinical laboratories. Taken together, based on the prevalence in general population the variant was classified as Benign. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
