This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1169 of the ATP7B protein (p.Met1169Val). This variant is present in population databases (rs749085322, gnomAD 0.008%). This missense change has been observed in individual(s) with Wilson disease (PMID: 7626145, 20517649, 35220961, 36096368). ClinVar contains an entry for this variant (Variation ID: 210485). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt ATP7B protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects ATP7B function (PMID: 18203200). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

This missense variant replaces methionine with valine at codon 1169 of the ATP7B protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). Functional studies have shown that this variant causes a mild copper transport deficit (PMID: 18203200). This variant has been reported in individuals affected with Wilson disease (PMID: 18203200, 20517649, 36096368). This variant has been identified in 11/280976 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
