Ambry Genetics | RCV000220360 | SCV000273451 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-02-09 | criteria provided, single submitter | clinical testing | The p.M620V variant (also known as c.1858A>G), located in coding exon 12 of the BRIP1 gene, results from an A to G substitution at nucleotide position 1858. The methionine at codon 620 is replaced by valine, an amino acid with highly similar properties. This amino acid position is 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. |

RCV001296861 | SCV001485837 | uncertain significance | Familial cancer of breast; Fanconi anemia complementation group J | 2021-10-16 | 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 230041). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces methionine with valine at codon 620 of the BRIP1 protein (p.Met620Val). The methionine residue is highly conserved and there is a small physicochemical difference between methionine and valine. |
