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 was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 198 curated pathogenic missense variants (we use a threshold of 10). The gene has 32 curated benign missense variants. Gene score misZ: -0.88091 (below the threshold of 3.09). Trascript score misZ: 0.82063 (below the threshold of 3.09). GenCC associations: The gene is linked to Wilson disease.
BP4
Computational evidence support a benign effect (MetaRNN=0.3664415).
