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]

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

Variant summary: The c.1426G>A (p.Ala476Thr) in ATP7B gene is a missense variant involves a non-conserved nucleotide and 3/4 in silico tools used predict benign outcome. The variant is located outside of any known functional domain or repeat, however no functional studies confirming an effect of this change on the protein function were published at the time of evaluation. The variant is present in the control population dataset of gnomAD (0.00048; 133/277032 chrs tested), predominantly in individuals of East Asian descent (0.0069; 131/18868 chrs tested). The frequency of the variant in the East Asian subpopulation exceeds the maximal expected allele frequency for a disease causing allele in ATP7B gene (0.0054), suggesting that this variant may represent a rare ethnic polymorphism. The variant has been reported in at least one affected individual as well as in healthy controls, and is cited as Likely Benign by a reputable database/clinical laboratory. Taken together, the variant was classified as likely benign, until new information becomes available. -
