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]

Wilson disease Uncertain:5
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 09, 2021This sequence change replaces serine, which is neutral and polar, with threonine, which is neutral and polar, at codon 406 of the ATP7B protein (p.Ser406Thr). This variant is present in population databases (rs1801243, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with ATP7B-related conditions. ClinVar contains an entry for this variant (Variation ID: 883817). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ATP7B protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaMar 20, 2018This 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. -
Uncertain significance, criteria provided, single submitterclinical testingAll of Us Research Program, National Institutes of HealthAug 06, 2024This missense variant replaces serine with threonine at codon 406 of the ATP7B protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with ATP7B-related disorders in the literature. This variant has been identified in 5/249516 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
