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.854A>G (p.His285Arg) variant has been reported in the published literature in individuals with breast cancer as well as in a reportedly healthy individual (PMIDs: 31871109 (2019), 32959997 (2020), 35264596 (2022), 33471991 (2021), see also LOVD (https://databases.lovd.nl/shared)). The frequency of this variant in the general population, 0.00076 (19/24968 chromosomes in African/African American subpopulation (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is higher than would generally be expected for pathogenic variants in this gene. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded conflicting predictions that this variant is benign or damaging. Based on the available information, we are unable to determine the clinical significance of this variant. -

The BRIP1 c.854A>G (p.His285Arg) missense change has a maximum subpopulation frequency of 0.076% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL is inconclusive about a pathogenic or benign effect of this variant on protein function, and functional studies have not been performed. This variant has been reported in individuals with breast cancer (PMID: 32885271, 32959997). 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. -

Color Diagnostics, LLC DBA Color Health

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This missense variant replaces histidine with arginine at codon 285 of the BRIP1 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with breast cancer (PMID: 32959997). This variant has been identified in 19/282340 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. -

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. -

Variant summary: BRIP1 c.854A>G (p.His285Arg) results in a non-conservative amino acid change located in the ATP-binding domain (IPR014001) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 6e-05 in 250946 control chromosomes. Although this frequency is higher than estimated for Autosomal Dominant Hereditary Breast And Ovarian Cancer Syndrome phenotype (6.3e-05), it is not significantly higher than estimated for a pathogenic variant in BRIP1 causing Autosomal Recessive Fanconi Anemia Complementation Group J (6e-05 vs 0.0004), allowing no conclusion about variant significance. c.854A>G has been reported in the literature as a VUS in settings of multigene panel testing in individuals affected with Breast Cancer (example, Uyisenga_2020, Adedokun_2020), however these reports 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: 31871109, 33471991, 32959997). ClinVar contains an entry for this variant (Variation ID: 142179). Based on the evidence outlined above, the variant was classified as uncertain significance. -

This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 285 of the BRIP1 protein (p.His285Arg). This variant is present in population databases (rs141055990, gnomAD 0.08%). This missense change has been observed in individual(s) with breast cancer (PMID: 26822149, 31871109, 32959997). ClinVar contains an entry for this variant (Variation ID: 142179). 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) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on BRIP1 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. -

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The BRIP1 c.854A>G variant is predicted to result in the amino acid substitution p.His285Arg. This variant was reported in multiple individuals with breast cancer (Table 5, Adedokun et al. 2020. PubMed ID: 31871109; Table 3, Uyisenga et al. 2020. PubMed ID: 32959997; Guindalini RSC et al. 2022. PubMed ID: 35264596). However, no additional studies were performed to help assess the pathogenicity of this variant. This variant is reported in 0.076% of alleles in individuals of African descent in gnomAD and has conflicting interpretations of pathogenicity in ClinVar ranging from likely benign to uncertain (https://www.ncbi.nlm.nih.gov/clinvar/variation/142179/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The BRIP1 p.His285Arg variant was not identified in the literature. The variant was identified in dbSNP (ID: rs141055990) as "With Uncertain significance allele" and ClinVar (classified as uncertain significance by Invitae, Ambry Genetics, GeneDx and four other submitters). The variant was identified in control databases in 19 of 276644 chromosomes at a frequency of 0.00007 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the African population in 19 of 24032 chromosomes (freq: 0.0008), while the variant was not observed in the Other, Latino, European, Ashkenazi Jewish, East Asian, Finnish, or South Asian populations. The p.His285 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
