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]

Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaMay 02, 2019This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpNov 17, 2016Variant summary: The ATP7B c.2355+13T>G variant involves the alteration of a non-conserved intronic nucleotide. One in silico tool predicts a benign outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. This variant was found in 357/119646 control chromosomes (1 homozygote), predominantly observed in the European (Finnish) subpopulation at a frequency of 0.0062046 (41/6608). This frequency is about the same frequency as the estimated maximal expected allele frequency of a pathogenic ATP7B variant (0.0054006), suggesting this is likely a benign polymorphism found primarily in the populations of European (Finnish) origin. The variant has been reported in the literature without strong evidence for causality, and in one case was present on the same chromosome as a known pathogenic variant, supporting the benign role of the variant. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. Taken together, this variant is classified as Benign. -
