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]

This sequence change replaces glycine, which is neutral and non-polar, with tryptophan, which is neutral and slightly polar, at codon 711 of the ATP7B protein (p.Gly711Trp). This variant is present in population databases (no rsID available, gnomAD 0.006%). This missense change has been observed in individual(s) with Wilson disease (PMID: 10502777, 31059521). ClinVar contains an entry for this variant (Variation ID: 555609). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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. -

The missense c.2131G>T(p.Gly711Trp) variant in ATP7B gene has been reported previously in homozygous and compound heterozygous states in individual(S) affected with Wilson's disease (Aaron R, et. al., 2021; Singh N, et. al., 2019). The p.Gly711Trp variant has been reported with allele frequency of 0.0008% in gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes. This variant has been reported to the ClinVar database as Uncertain Significance / Likely Pathogenic / Pathogenic. The amino acid change p.Gly711Trp in ATP7B is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Gly at position 711 is changed to a Trp changing protein sequence and it might alter its composition and physico-chemical properties. Additional functional studies will be required to prove the pathogenicity of this variant. For these reasons, this variant has been classified as Likely Pathogenic. -

Significance: Pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

Variant summary: ATP7B c.2131G>T (p.Gly711Trp) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 248946 control chromosomes. c.2131G>T has been reported in the literature in multiple individuals affected with Wilson Disease (WD) further supported by identification of very low serum cerruloplasmin and serum copper and the classic stigmata of WD in all cases (example, Singh_2019, Curtis_1999). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as uncertain significance while not citing all publications utilized in the context of this evaluation. Based on the evidence outlined above, the variant was classified as pathogenic. -
