Labcorp Genetics (formerly Invitae), Labcorp RCV000464547 SCV000547264 uncertain significance Familial cancer of breast; Fanconi anemia complementation group J 2022-03-07 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 381 of the BRIP1 protein (p.Met381Lys). 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: 407809). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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.
Ambry Genetics RCV001017422 SCV001178501 uncertain significance Hereditary cancer-predisposing syndrome 2019-02-12 criteria provided, single submitter clinical testing The p.M381K variant (also known as c.1142T>A), located in coding exon 8 of the BRIP1 gene, results from a T to A substitution at nucleotide position 1142. The methionine at codon 381 is replaced by lysine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
