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]

Pathogenic, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Apr 30, 2018	Variant summary: ATP7B c.1847G>A (p.Arg616Gln) results in a conservative amino acid change located in the Heavy metal-associated domain of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4.9e-05 in 246238 control chromosomes. This frequency is not higher than expected for a pathogenic variant in ATP7B causing Wilson Disease (4.9e-05 vs 0.0054), allowing no conclusion about variant significance. c.1847G>A has been reported in the literature in multiple individuals affected with Wilson Disease as both a compound heterozygous and homozygous allele (Loudianos_2003, Ljubic_2016). These data indicate that the variant is very likely to be associated with disease. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as pathogenic. -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 25, 2024	This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 616 of the ATP7B protein (p.Arg616Gln). This variant is present in population databases (rs752850609, gnomAD 0.009%). This missense change has been observed in individual(s) with Wilson disease (PMID: 12885331, 21610751, 22735241, 26799313). ClinVar contains an entry for this variant (Variation ID: 552606). 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 expected to disrupt ATP7B protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -

Pathogenic, criteria provided, single submitter	clinical testing	All of Us Research Program, National Institutes of Health	Aug 06, 2024	This missense variant replaces arginine with glutamine at codon 616 of the ATP7B protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with Wilson disease (PMID: 10502777, 12885331, 16283883, 17264425, 18286826, 18034201, 21610751, 22735241, 23518715, 23789284, 26799313). In many of these affected individuals, this variant has been determined to be homozygous or compound heterozygous with another pathogenic variant in the same gene (PMID: 12885331, 17264425, 21610751, 22735241, 23518715, 26799313). These data indicate that this variant contributes to Wilson disease in an autosomal recessive manner. This variant has been identified in 12/249570 chromosomes in the general population by the Genome Aggregation Database (gnomAD). A different variant occurring at the same codon, p.Arg616Trp, is classified as pathogenic (Clinvar Variation ID: 863093), indicating that arginine at this position is important for ATP7b protein function. Based on the available evidence, this variant is classified as Pathogenic. -
