Genes affected

BRIP1 (HGNC:20473): (BRCA1 interacting helicase 1) The protein encoded by this gene is a member of the RecQ DEAH helicase family and interacts with the BRCT repeats of breast cancer, type 1 (BRCA1). The bound complex is important in the normal double-strand break repair function of breast cancer, type 1 (BRCA1). This gene may be a target of germline cancer-inducing mutations.

Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Dec 11, 2020	This missense variant replaces arginine with leucine at codon 855 of the BRIP1 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 3/251308 chromosomes 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Jan 06, 2022	The p.R855L variant (also known as c.2564G>T), located in coding exon 17 of the BRIP1 gene, results from a G to T substitution at nucleotide position 2564. The arginine at codon 855 is replaced by leucine, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 855 of the BRIP1 protein (p.Arg855Leu). This variant is present in population databases (rs200894063, gnomAD 0.01%). 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: 407848). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt BRIP1 protein function with a negative predictive value of 80%. 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. -

The observed missense c.2564G>T (p.Arg855Leu) variant in BRIP1 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.Arg855Leu variant is present with allele frequency of 0.001% in gnomAD Exomes. This variant has been submitted to the ClinVar database as Uncertain Significance. Computational evidence (Polyphen - Benign, SIFT - Damaging and MutationTaster - Polymorphism) predicts conflicting evidence on protein structure and function for this variant. The reference amino acid of p.Arg855Leu in BRIP1 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Arg at position 855 is changed to a Leu changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as a Variant of Uncertain Significance (VUS). -
