Ambry Genetics RCV000218444 SCV000273900 uncertain significance Hereditary cancer-predisposing syndrome 2021-03-09 criteria provided, single submitter clinical testing The p.K297Q variant (also known as c.889A>C), located in coding exon 6 of the BRIP1 gene, results from an A to C substitution at nucleotide position 889. The lysine at codon 297 is replaced by glutamine, an amino acid with 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.
Color Diagnostics, LLC DBA Color Health RCV000218444 SCV001353236 uncertain significance Hereditary cancer-predisposing syndrome 2023-12-05 criteria provided, single submitter clinical testing This missense variant replaces lysine with glutamine at codon 297 of the BRIP1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with BRIP1-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
Labcorp Genetics (formerly Invitae), Labcorp RCV001857764 SCV002205860 uncertain significance Familial cancer of breast; Fanconi anemia complementation group J 2023-10-30 criteria provided, single submitter clinical testing This sequence change replaces lysine, which is basic and polar, with glutamine, which is neutral and polar, at codon 297 of the BRIP1 protein (p.Lys297Gln). 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: 230369). 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 BRIP1 protein function with a negative 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.
