GeneDx RCV000222877 SCV000279520 uncertain significance not provided 2015-10-27 criteria provided, single submitter clinical testing This variant is denoted BRIP1 c.2365G>T at the cDNA level, p.Val789Leu (V789L) at the protein level, and results in the change of a Valine to a Leucine (GTG>TTG). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. BRIP1 Val789Leu 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 Leucine share similar properties, this is considered a conservative amino acid substitution. BRIP1 Val789Leu occurs at a position that is conserved in mammals and is not located in a known functional domain (UniProt). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available evidence, it is unclear whether BRIP1 Val789Leu is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
Invitae RCV000689257 SCV000816899 uncertain significance Familial cancer of breast; Fanconi anemia, complementation group J 2018-05-18 criteria provided, single submitter clinical testing This sequence change replaces valine with leucine at codon 789 of the BRIP1 protein (p.Val789Leu). The valine residue is moderately conserved and there is a small physicochemical difference between valine and leucine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with BRIP1-related disease. ClinVar contains an entry for this variant (Variation ID: 234579). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
