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 -20 ACMG points.

BP4

This position, referring to a specific DNA site, is a probable branch point but is likely benign (scored 0 / 10, using the threshold of <=3). The score ranges from 0 to 10, with values ≤3 considered benign and >5 classified as pathogenic. Computational evidence support a benign effect (BayesDel_noAF=-0.83).

BP6

Variant 13-51950424-C-T is Benign according to our data. Variant chr13-51950424-C-T is described in ClinVar as [Benign]. Clinvar id is 254764.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BA1

GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.471 is higher than 0.05.
