The NM_000053.4(ATP7B):c.2495A>G (p.Lys832Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene ATP7B is a known oncogene (CancerMine: 1 oncogene citations). The variant allele was found at a cumulative frequency of 0.562 (AC=907,251) in the gnomAD database across 1,613,790 control chromosomes, including 256,999 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.608. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★★). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.K832= (synonymous): Likely_benign (ClinVar VariationId 1652777, 1 star); p.K832R: Likely_benign (ClinVar VariationId 1122352, 1 star); p.K832T: Uncertain_significance (ClinVar VariationId 2266434, 1 star) The variant has been observed in cBioPortal in 3 samples across 3 studies and 3 cancer types; somatic enrichment level: SUPPORTING_LOW (Observed in a small number of cBioPortal cases.). This exact variant is curated in the UniProt human variants database as Uncertain Significance; it is also listed as a COSMIC curated somatic variant.

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]

Classification according to ACGS-UK Somatic Oncogenicity v2025

Classification was made for transcript:

Our verdict: Likely_benign. The variant received -2 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	O7Mutational hotspot or critical domain		Supporting: cancerhotspots.org hit, critical domain, or missense neighbourhood hotspot; No cancerhotspots.org hit at this position; UniProt domain: 0 pathogenic, 0 benign.; ±8 AA neighbourhood: 10 pathogenic, 0 benign (OR vs. background: 105.0); Variant does not impact splicing — splice-hotspot path not applicable
	O8Missense constraint in gene or region		Missense in gene/domain constrained for missense variation where missense is common disease mechanism (O8 supporting); Gene/disease mechanism: missense is a common mechanism of oncogenesis; gnomAD missense Z-score: 0.84 (threshold ≥3.09 for constraint); Domain-level constraint: variant is in a critically constrained functional domain (IS_AT_CRITICAL_DOMAIN)
	B1High frequency in general population		GnomAD effective popmax AF >1% — B1 stand-alone benign; GnomAD effective popmax AF = 0.608 — exceeds 1% threshold (B1 applied)
