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.

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.10A>G (p.Met4Val) results in a conservative amino acid change in the encoded protein sequence. Algorithms developed to predict the effect of missense changes on protein structure and function all suggest that this variant is likely to be tolerated. The variant allele was found at a frequency of 4e-06 in 251232 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance.c.10A>G has been reported in the literature in individuals with a diagnosis of or predisposition to hereditary cancer (e.g. Tsaousis_2019, Shao_2020). These report(s) do not provide unequivocal conclusions about association of the variant with 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: 31742824, 31159747). ClinVar contains an entry for this variant (Variation ID: 232285). Based on the evidence outlined above, the variant was classified as uncertain significance. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 4 of the BRIP1 protein (p.Met4Val). This variant is present in population databases (rs45512093, gnomAD 0.003%). This missense change has been observed in individual(s) with a personal or family history of breast and/or ovarian cancer or clinical features of Lynch syndrome (PMID: 25980754, 26921362, 31159747). ClinVar contains an entry for this variant (Variation ID: 232285). 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. -

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Observed in individuals with breast cancer or a history of Lynch syndrome-associated cancer and/or colon polyps (Yurgelun et al., 2015; Easton et al., 2016); This variant is associated with the following publications: (PMID: 25980754, 31159747, 26921362, 31742824) -

Review Status:no assertion criteria provided
Collection Method:clinical testing

The BRIP1 p.Met4Val variant was identified in 2 of 5146 proband chromosomes (frequency: 0.0004) from individuals or families with breast cancer or lynch syndrome and was not identified in 2246 control chromosomes from healthy individuals (Easton 2016, Yurgelun 2015). The variant was also identified in dbSNP (ID: rs45512093) as "With Uncertain significance allele", ClinVar (classified as likely benign by Ambry Genetics; as uncertain significance by Invitae), MutDB, and in the Zhejiang University database. The variant was identified in control databases in 2 of 277002 chromosomes at a frequency of 0.00001 (Genome Aggregation Database Feb 27, 2017). It was observed in the following populations: European in 1 of 126564 chromosomes (freq: 0.00001), and South Asian in 1 of 30780 chromosomes (freq: 0.00003); but was not observed in the African, Other, Latino, Ashkenazi Jewish, East Asian, and Finnish populations. The p.Met4 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and 2 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. 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. -
