Invitae RCV000696414 SCV000824975 uncertain significance Hereditary breast ovarian cancer syndrome 2022-02-17 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). 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 not expected to disrupt BRCA1 protein function. ClinVar contains an entry for this variant (Variation ID: 574474). This missense change has been observed in individual(s) with breast cancer (PMID: 30415210). This sequence change replaces isoleucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 591 of the BRCA1 protein (p.Ile591Met).
University of Washington Department of Laboratory Medicine, University of Washington RCV003158043 SCV003849744 likely benign Hereditary cancer-predisposing syndrome 2023-03-23 criteria provided, single submitter curation Missense variant in a coldspot region where missense variants are very unlikely to be pathogenic (PMID:31911673).
Quest Diagnostics Nichols Institute San Juan Capistrano RCV003478426 SCV004222575 uncertain significance not provided 2022-10-25 criteria provided, single submitter clinical testing It has not been reported in large, multi-ethnic general populations (http://gnomad.broadinstitute.org). In the published literature, the variant has been reported in at least one individual with breast cancer (PMID: 30415210 (2018)). Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded conflicting predictions that this variant is benign or damaging. Based on the available information, we are unable to determine the clinical significance of this variant.
