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 creates a premature translational stop signal (p.Gln1351*) in the ATP7B gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ATP7B are known to be pathogenic (PMID: 10441329, 16283883). This variant is present in population databases (rs786204578, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with Wilson disease (PMID: 11180609, 16283883, 26799313). ClinVar contains an entry for this variant (Variation ID: 188947). For these reasons, this variant has been classified as Pathogenic. -

The p.Gln1351X variant in ATP7B has been reported in >10 individuals with Wilson disease, including at least 4 compound heterozygous and 1 homozygous individual (Beyersdorff 2006, Ferenci 2007, Folhoffer 2007, Genschel 2001, Gromadzka 2005, Moller 2011, Petrasek 2007, Xiong 2015). This variant has been identified in 0.0009% (1/110774) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This nonsense variant leads to a premature termination codon at position 1351, which is predicted to lead to a truncated or absent protein. Loss of function of the ATP7B gene is an established disease mechanism in autosomal recessive Wilson disease. In summary, this variant meets criteria to be classified as pathogenic for autosomal recessive Wilson disease. ACMG/AMP criteria applied: PVS1, PM3_VeryStrong, PM2, PP4. -

Variant summary: The ATP7B c.4051C>T (p.Gln1351X) variant results in a premature termination codon, predicted to cause a truncated or absent ATP7B protein due to nonsense mediated decay, which are commonly known mechanisms for disease. This variant was found in 1/242182 control chromosomes at a frequency of 0.0000041, which does not exceed the estimated maximal expected allele frequency of a pathogenic ATP7B variant (0.0054006). Multiple publications cite the variant in compound heterozygote and homozygote affected individuals. A clinical diagnostic laboratory classified this variant as likely pathogenic. Taken together, this variant is classified as pathogenic. -

This variant changes 1 nucleotide in exon 20 of the ATP7B gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been observed in many individuals affected with autosomal recessive Wilson disease (PMID: 11180609, 16283883, 17154398, 17272994, 21273697, 21334398, 21610751, 22677543, 23885147, 24517292, 26799313, 30230192, 34400371, 35626790), including one homozygous individual (PMID: 17272994), four individuals who were confirmed to carry another pathogenic variant in trans (PMID: 17272994, 21610751, 26799313), and multiple individuals who carried another pathogenic variant in unknown phase (PMID: 17154398, 23885147, 24517292, 35626790). This variant has been identified in 1/245256 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of ATP7B function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. -

The ATP7B c.4051C>T, p.Gln1351Ter variant (rs786204578) has been reported in multiple individuals with Wilson's disease (Folhoffer 2007, Genschel 2000, Gromadzka 2005, Moller 2011, Vrabelova 2005). It is listed in ClinVar (Variation ID: 188947), and observed once in the Genome Aggregation Database general population database (1/242182 alleles). The variant introduces a premature termination codon, and is predicted to result in a truncated protein or an absent transcript. Based on the above information, the variant is classified as pathogenic. References: Folhoffer A et al. Novel mutations of the ATP7B gene among 109 Hungarian patients with Wilson's disease.
