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.

The BRIP1 c.3444C>A; p.Asp1148Glu variant (rs28997573) is reported in the literature in individuals with hereditary cancer syndromes but is also reported in healthy controls (Bhai 2021, Ramus 2015, Seal 2006, Tung 2015, Yurgelun 2015). This variant is also reported in ClinVar (Variation ID: 133758). It is observed in the general population with an overall allele frequency of 0.01% (29/281212 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses predict that this variant is neutral (REVEL: 0.072). Due to limited information, the clinical significance of this variant is uncertain at this time. References: Bhai P et al.

Variant summary: BRIP1 c.3444C>A (p.Asp1148Glu) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0001 in 249810 control chromosomes. Although the observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 3-fold of the estimated maximal expected allele frequency for a pathogenic variant in BRIP1 causing Hereditary Breast And Ovarian Cancer Syndrome phenotype (6.3e-05), this frequency is not significantly higher than estimated for a pathogenic variant in BRIP1 causing Autosomal Recessive Fanconi Anemia Complementation Group J (0.0001 vs 0.0004), allowing no conclusion about variant significance. c.3444C>A has been reported in the literature in individuals affected with different types of cancer including breast cancer, ovarian cancer, Lynch syndrome, kidney renal clear cell carcinoma and uterine corpus endometrial carcinoma (e.g. Easton_2016, Lu_2015, Ramus_2015, Seal_2016, Tung_2015, Yurgelun_2015) but also, in controls (e.g. Easton_2016, Ramus_2015). These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Breast and Ovarian Cancer Syndrome or Fanconi Anemia Complementation Group J. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 26921362, 23555315, 26689913, 26315354, 17033622, 25186627, 25980754). ClinVar contains an entry for this variant (Variation ID: 133758). Based on the evidence outlined above, the variant was classified as uncertain significance. -

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 aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 1148 of the BRIP1 protein (p.Asp1148Glu). This variant is present in population databases (rs28997573, gnomAD 0.02%). This missense change has been observed in individual(s) with Lynch syndrome, ovarian cancer, breast cancer, and renal clear cell carcinoma (PMID: 25186627, 25980754, 26315354, 26689913). ClinVar contains an entry for this variant (Variation ID: 133758). 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. -
