Ambry Genetics | RCV000570460 | SCV000661004 | uncertain significance | Hereditary cancer-predisposing syndrome | 2016-02-26 | criteria provided, single submitter | clinical testing | The p.M297K variant (also known as c.890T>A), located in coding exon 9 of the BRCA1 gene, results from a T to A substitution at nucleotide position 890. The methionine at codon 297 is replaced by lysine, an amino acid with 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. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

Invitae | RCV001312407 | SCV001502862 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2023-10-29 | criteria provided, single submitter | clinical testing | This sequence change replaces methionine, which is neutral and non-polar, with lysine, which is basic and polar, at codon 297 of the BRCA1 protein (p.Met297Lys). This variant is present in population databases (rs80356924, gnomAD 0.0009%). This missense change has been observed in individual(s) with breast and/or ovarian cancer (PMID: 27062684). ClinVar contains an entry for this variant (Variation ID: 55742). 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 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. |
