Description

This sequence change replaces isoleucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 2828 of the BRCA2 protein (p.Ile2828Met). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with personal and/or family history of breast cancer (PMID: 15955690). ClinVar contains an entry for this variant (Variation ID: 627757). 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 BRCA2 protein function. 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.
