Labcorp Genetics (formerly Invitae), Labcorp RCV000822513 SCV000963320 uncertain significance Hereditary breast ovarian cancer syndrome 2024-01-10 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 897 of the BRCA2 protein (p.Glu897Gln). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BRCA2-related conditions. ClinVar contains an entry for this variant (Variation ID: 664416). 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 with a negative predictive value of 95%. 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.
Ambry Genetics RCV002453896 SCV002739758 uncertain significance Hereditary cancer-predisposing syndrome 2024-03-07 criteria provided, single submitter clinical testing The p.E897Q variant (also known as c.2689G>C), located in coding exon 10 of the BRCA2 gene, results from a G to C substitution at nucleotide position 2689. The glutamic acid at codon 897 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear.
