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]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Gly869*) 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 (rs191312027, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with Wilson disease (PMID: 31708252). ClinVar contains an entry for this variant (Variation ID: 1338419). For these reasons, this variant has been classified as Pathogenic. -

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

DNA sequence analysis of the ATP7B gene demonstrated the c.2605G>T sequence change in exon 11, that results in the creation of a premature stop codon at amino acid position 869, p.Gly869*. This pathogenic sequence change is predicted to result in an abnormal transcript, which may be degraded, or may lead to the production of a truncated ATP7B protein with potentially abnormal function. Truncating variants in ATP7B have been previously described in patients with Wilson disease (PMID: 18373411). This sequence change was identified with another pathogenic ATP7B variant in a patient. -
