Invitae RCV000815937 SCV000956417 uncertain significance Hereditary breast ovarian cancer syndrome 2023-07-26 criteria provided, single submitter clinical testing 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. 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. ClinVar contains an entry for this variant (Variation ID: 659006). This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 760 of the BRCA1 protein (p.Thr760Ile). This variant is present in population databases (no rsID available, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with BRCA1-related conditions.
Ambry Genetics RCV002442733 SCV002732146 likely benign Hereditary cancer-predisposing syndrome 2021-12-10 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
