Ambry Genetics | RCV000570578 | SCV000661124 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-04-21 | criteria provided, single submitter | clinical testing | The p.V1341I variant (also known as c.4021G>A), located in coding exon 9 of the BRCA1 gene, results from a G to A substitution at nucleotide position 4021. The valine at codon 1341 is replaced by isoleucine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV000692212 | SCV000820024 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2024-06-21 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 1341 of the BRCA1 protein (p.Val1341Ile). This variant is present in population databases (rs762908108, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with BRCA1-related conditions. ClinVar contains an entry for this variant (Variation ID: 479257). 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. |
