Description

This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 782 of the BRIP1 protein (p.Ile782Val). This variant is present in population databases (rs142806416, gnomAD 0.003%). This missense change has been observed in individual(s) with breast cancer and/or pancreatic cancer (PMID: 26921362, 28767289, 34326862). ClinVar contains an entry for this variant (Variation ID: 142346). 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 BRIP1 protein function with a negative predictive value of 80%. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on BRIP1 function (PMID: 31822495). RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (Invitae). 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.
