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	Labcorp Genetics (formerly Invitae), Labcorp	Mar 02, 2023	This sequence change creates a premature translational stop signal (p.Gln188*) 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 (no rsID available, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with Wilson disease (PMID: 17949296, 23518715). ClinVar contains an entry for this variant (Variation ID: 552374). 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	Feb 05, 2024	This variant changes 1 nucleotide in exon 2 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 the compound heterozygous state in individuals affected with autosomal recessive Wilson disease (PMID: 17949296, 23518715), indicating that this variant contributes to disease. This variant has been identified in 1/31396 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. -
