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 submitterclinical testingIllumina Laboratory Services, IlluminaJun 15, 2017This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

Hereditary cancer-predisposing syndrome Uncertain:2Benign:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2022The p.R106C variant (also known as c.316C>T), located in coding exon 3 of the BRIP1 gene, results from a C to T substitution at nucleotide position 316. The arginine at codon 106 is replaced by cysteine, an amino acid with highly dissimilar properties. This alteration was observed within 1 of 13213 individuals with a personal history of breast cancer and 1/5242 controls (Easton DF et al. J Med Genet, 2016 05;53:298-309). It was also reported in a family in which the variant was present in two siblings affected with breast cancer and absent from two cancer-free siblings (Grasel RS et al. Front Oncol, 2020 Oct;10:571330). This variant has been reported in a familial prostate cancer kindred and in one individual with colorectal cancer diagnosed under age 50 (Ray AM et al. Br. J. Cancer. 2009 Dec;101:2043-7; Pearlman R et al. JAMA Oncol. 2017 Apr;3:464-471). This amino acid position is poorly 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. -

Ovarian neoplasm Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingDivision of Medical Genetics, University of WashingtonNov 22, 2019This variant has been identified in individuals with breast, colon and prostate cancer (Ray 2009, Easton 2016, Pearlman 2017), but has not to our knowledge been reported in an individual with ovarian cancer. The majority of pathogenic variants reported in the BRIP1 gene to date are truncating variants. This variant has an overall allele frequency of 0.0001 in the Broad Institute ExAC Browser (http://exac.broadinstitute.org/). In silico analyses indicate that this variant may not alter protein structure/function. Thus, it is unknown at this time whether this variant increases cancer risk. BP4 -

BRIP1-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesDec 14, 2022The BRIP1 c.316C>T variant is predicted to result in the amino acid substitution p.Arg106Cys. This variant was reported in individuals with prostate cancer, lung adenocarcinoma, or colon cancer (Table 3, Ray et al. 2009. PubMed ID: 19935797; Supplementary data set 12, Lu et al. 2015. PubMed ID: 26689913; eTable 2, Pearlman et al. 2017. PubMed ID: 27978560). This variant was also reported as uncertain in a cohort study of hereditary cancer testing (Table S1, Velázquez. 2020. PubMed ID: 32522261). In a case control study, this variant was identified in one individual with breast cancer and found in one unaffected individual (Table S1, Easton et al. 2016. PubMed ID: 26921362). In addition, a different variant affecting the same amino acid (p.Arg106His) was reported in individuals with rectum cancer/pancreatic adenocarcinoma (eTable 2, Pearlman et al. 2017. PubMed ID: 27978560; Shindo. 2017. PubMed ID: 28767289). This variant is reported in 0.020% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/17-59934482-G-A) and has conflicting interpretations regarding its pathogenicity in ClinVar, ranging from likely benign to uncertain (https://www.ncbi.nlm.nih.gov/clinvar/variation/128184/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
not specified Benign:1
Likely benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpSep 19, 2017Variant summary: The BRIP1 c.316C>T (p.Arg106Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. 3/4 in silico tools predict a benign outcome for this variant (SNPsandGO not captured due to low reliability index). The variant was found in the control population dataset of gnomAD in 32/287682 control chromosomes, predominantly observed in the Latino subpopulation at a frequency of 0.000203 (7/34416). This frequency is about 3 times the estimated maximal expected allele frequency of a pathogenic BRIP1 variant (0.0000625), suggesting this is likely a benign polymorphism found primarily in the populations of Latino origin. The variant has been reported in affected individuals in the literature, without strong evidence for causality (Ray_2009, Easton_2016, Pearlman_2016). Multiple clinical diagnostic laboratories/reputable databases classified this variant as uncertain significance. Taken together, based on the relatively high allele frequency of the variant in the control population, this variant is classified as likely benign. -
