Description

This sequence change replaces glutamic acid, which is acidic and polar, with aspartic acid, which is acidic and polar, at codon 602 of the BAP1 protein (p.Glu602Asp). This variant is present in population databases (no rsID available, gnomAD 0.007%). This missense change has been observed in individual(s) with uveal melanoma (PMID: 23171164). ClinVar contains an entry for this variant (Variation ID: 472679). 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 not expected to disrupt BAP1 protein function with a negative predictive value of 80%. 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.
