GeneDx RCV000485017 SCV000570306 uncertain significance not provided 2016-05-13 criteria provided, single submitter clinical testing This variant is denoted BRIP1 c.1165G>T at the cDNA level, p.Val389Phe (V389F) at the protein level, and results in the change of a Valine to a Phenylalanine (GTT>TTT). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. BRIP1 Val389Phe was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Valine and Phenylalanine differ in some properties, this is considered a semi-conservative amino acid substitution. BRIP1 Val389Phe occurs at a position where amino acids with properties similar to Valine are tolerated across species and is located within the helicase and helicase ATP-binding domain (Cantor 2011, Uniprot). In silico analyses predict that this variant is probably damaging to protein structure and function. Based on currently available evidence, it is unclear whether BRIP1 Val389Phe is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
Labcorp Genetics (formerly Invitae), Labcorp RCV001344442 SCV001538495 uncertain significance Familial cancer of breast; Fanconi anemia complementation group J 2022-02-09 criteria provided, single submitter clinical testing ClinVar contains an entry for this variant (Variation ID: 421188). 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 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"). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.004%). This sequence change replaces valine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 389 of the BRIP1 protein (p.Val389Phe).
