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]

ACMG classification
Classification made for transcript
Verdict is Benign. Variant got -7 ACMG points.
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.75).
BP6
Variant 13-51950363-G-A is Benign according to our data. Variant chr13-51950363-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 254765.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=6, Uncertain_significance=2}. Variant chr13-51950363-G-A is described in Lovd as [Likely_benign]. Variant chr13-51950363-G-A is described in Lovd as [Benign].
BP7
Synonymous conserved (PhyloP=-2.07 with no splicing effect.
BS2
High Homozygotes in GnomAdExome4 at 2 AR geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Uncertain significance, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Feb 01, 2019 | This 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. - |
