Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PM1PM2PM5PP3_StrongPP5_Very_Strong
The NM_000053.4(ATP7B):c.2963G>T(p.Gly988Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,518 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. G988R) has been classified as Likely pathogenic.

Variant summary: ATP7B c.2963G>T (p.Gly988Val) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 248932 control chromosomes (gnomAD). c.2963G>T has been reported in the literature in individuals affected with Wilson Disease (Schushan_2012, Cheng_2017, Li_2019, Singh_2019). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 27982432, 30702195, 22692182, 31059521, 35220961). ClinVar contains an entry for this variant (Variation ID: 2137518). Based on the evidence outlined above, the variant was classified as likely pathogenic. -
This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 988 of the ATP7B protein (p.Gly988Val). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Wilson disease (PMID: 30702195). 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) performed at Invitae indicates that this missense variant is expected to disrupt ATP7B protein function. 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. -
