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 testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpJun 17, 2024Variant summary: BRIP1 c.3275C>T (p.Pro1092Leu) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 7.7e-06 in 261342 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.3275C>T has been reported in the literature in individuals affected with Hereditary Breast And Ovarian Cancer Syndrome. These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 26921362). ClinVar contains an entry for this variant (Variation ID: 136149). Based on the evidence outlined above, the variant was classified as uncertain significance. -
Likely benign, criteria provided, single submitterclinical testingGeneDxNov 01, 2017This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2019This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Familial cancer of breast;C1836860:Fanconi anemia complementation group J Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 20, 2022This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1092 of the BRIP1 protein (p.Pro1092Leu). This variant is present in population databases (rs587780830, gnomAD 0.002%). This missense change has been observed in individual(s) with breast cancer (PMID: 26921362). ClinVar contains an entry for this variant (Variation ID: 136149). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
BRIP1-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesJun 26, 2024The BRIP1 c.3275C>T variant is predicted to result in the amino acid substitution p.Pro1092Leu. This variant has been reported in an individual with breast cancer (Table S1, Easton et al. 2016. PubMed ID: 26921362). This variant is reported in 0.0018% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant has conflicting interpretations regarding its pathogenicity in ClinVar, ranging from likely benign to uncertain (https://www.ncbi.nlm.nih.gov/clinvar/variation/136149/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
