Ambry Genetics RCV000130159 SCV000184994 uncertain significance Hereditary cancer-predisposing syndrome 2023-11-09 criteria provided, single submitter clinical testing The p.L909V variant (also known as c.2725C>G), located in coding exon 18 of the BRIP1 gene, results from a C to G substitution at nucleotide position 2725. The leucine at codon 909 is replaced by valine, 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.
Color Diagnostics, LLC DBA Color Health RCV000130159 SCV001347585 uncertain significance Hereditary cancer-predisposing syndrome 2023-12-04 criteria provided, single submitter clinical testing This missense variant replaces leucine with valine at codon 909 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 RCV002512538 SCV003220360 uncertain significance Familial cancer of breast; Fanconi anemia complementation group J 2022-09-03 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 141576). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 909 of the BRIP1 protein (p.Leu909Val).
