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.

Variant summary: BRIP1 c.3050C>T (p.Pro1017Leu) 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 4e-06 in 251410 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.3050C>T has been reported in the literature in the settings of multigene panel testing in an individual with epithelial ovarian cancer (example, Ramus_2016) and in unaffected controls as well as individuals affected with breast cancer from a UK cohort (example, Easton_2016). 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. Six clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments (likely benign, n=2; VUS, n=4). Based on the evidence outlined above, the variant was classified as uncertain significance. -

The BRIP1 c.3353A>G (p.Asn1118Ser) missense change has a maximum subpopulation frequency of 0.00088% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a benign effect on protein function, but to our knowledge this prediction has not been confirmed by functional studies. This variant has been reported in 3 of 13,213 breast cancer cases and 2 of 5,242 controls in case control study (PMID: 26921362), and in 1 of in 3,236 invasive ovarian carcinoma patients and 0 of 3,431 control patients of European origin (PMID: 26315354). It has also been reported in one individual in a database of women older than 70 years of age who have never had cancer (FLOSSIES database, https://whi.color.com/), and in 1 of 1,358 control individuals collected as part of a non-cancer studies (PMID: 29641532). To our knowledge, this variant has not been reported in individuals with Fanconi anemia. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This 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. -

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1017 of the BRIP1 protein (p.Pro1017Leu). This variant is present in population databases (rs747907706, gnomAD 0.0009%). This missense change has been observed in individual(s) with ovarian and/or breast cancer (PMID: 26315354, 26921362). ClinVar contains an entry for this variant (Variation ID: 186283). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt BRIP1 protein function with a negative predictive value of 95%. 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. -
