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	Ambry Genetics	Jul 19, 2023	The p.R403W variant (also known as c.1207C>T), located in coding exon 8 of the BRIP1 gene, results from a C to T substitution at nucleotide position 1207. The arginine at codon 403 is replaced by tryptophan, an amino acid with dissimilar properties. This alteration has been reported in 2/1824 patients with triple negative breast cancer (Couch FJ et al. J. Clin. Oncol. 2015 Feb;33:304-11) and in 1/118 renal cell carcinoma patients (Smith PS et al. Genes Chromosomes Cancer, 2021 Jan;60:5-16). In another study, this alteration was not detected in 13213 breast cancer cases but was detected in 1/5242 controls (Easton DF et al. J. Med. Genet. 2016 May;53:298-309). 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Feb 16, 2023	This missense variant replaces arginine with tryptophan at codon 403 of the BRIP1 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with breast cancer (PMID: 25452441, 33471991), renal cell carcinoma (PMID: 32830346), and unaffected individuals in breast cancer studies (PMID: 26921362, 33471991). This variant has been identified in 13/282352 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. -

Variant summary: BRIP1 c.1207C>T (p.Arg403Trp) results in a non-conservative amino acid change located in the Helicase-like, DEXD box c2 type domain of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4.4e-05 in 250950 control chromosomes (gnomAD). This frequency is not significantly higher than expected for a pathogenic variant in BRIP1 causing Breast Cancer (4.4e-05 vs 6.3e-05), allowing no conclusion about variant significance. c.1207C>T has been reported in the literature in individuals affected with Breast Cancer (Couch_2015). This report does not provide an unequivocal conclusion about association of the variant with Breast Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Six ClinVar submissions (evaluation after 2014) cites the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 403 of the BRIP1 protein (p.Arg403Trp). This variant is present in population databases (rs369631413, gnomAD 0.008%). This missense change has been observed in individual(s) with breast cancer (PMID: 25452441). ClinVar contains an entry for this variant (Variation ID: 136141). 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 expected to disrupt BRIP1 protein function with a positive 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. -
