Invitae | RCV000822452 | SCV000963254 | uncertain significance | Wilson disease | 2021-08-30 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine with valine at codon 780 of the ATP7B protein (p.Leu780Val). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and valine. 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. 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. ClinVar contains an entry for this variant (Variation ID: 664367). This variant has been observed in individual(s) with Wilson disease (Invitae). This variant is not present in population databases (ExAC no frequency). |
