Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM2PM5PP3_StrongPP5_Moderate
The NM_000053.4(ATP7B):c.3053C>A(p.Ala1018Glu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A1018V) has been classified as Likely pathogenic.

Wilson disease Pathogenic:1
In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.Ala1018 amino acid residue in ATP7B. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 17154398, 30884209, 31059521; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ATP7B protein function. This variant has not been reported in the literature in individuals affected with ATP7B-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces alanine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 1018 of the ATP7B protein (p.Ala1018Glu). -
