Ambry Genetics | RCV000568892 | SCV000668960 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-06-12 | criteria provided, single submitter | clinical testing | The p.L679F variant (also known as c.2035C>T), located in coding exon 13 of the BRIP1 gene, results from a C to T substitution at nucleotide position 2035. The leucine at codon 679 is replaced by phenylalanine, an amino acid with highly similar properties. This amino acid position is highly 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. |

RCV000701584 | SCV000830391 | uncertain significance | Familial cancer of breast; Fanconi anemia complementation group J | 2023-12-31 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 679 of the BRIP1 protein (p.Leu679Phe). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 483197). 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 expected to disrupt BRIP1 protein function with a positive predictive value of 80%. 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. |
Quest Diagnostics Nichols Institute San Juan Capistrano | RCV003478251 | SCV004220695 | uncertain significance | not provided | 2022-12-23 | criteria provided, single submitter | clinical testing | The variant has not been reported in the published literature. The frequency of this variant in the general population, 0.0000066 (1/152138 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. 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. |
