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.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 218 of the BRIP1 protein (p.Cys218Tyr). This variant is present in population databases (rs754242563, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 407824). 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. -

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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This missense variant replaces cysteine with tyrosine at codon 218 of the BRIP1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 16/250382 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. -

KCCC/NGS Laboratory, Kuwait Cancer Control Center

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces cysteine with tyrosine at codon 218 of the BRIP1 protein (p.Cys218Tyr). The cysteine residue is weakly conserved and there is a large physicochemical difference between cysteine and tyrosine. This variant is present in population database gnomAD (0.0064%). This variant has not been reported in the literature in individuals with BRIP1-related disease. ClinVar contains an entry for this variant (Variation ID: 407824) with 4 submissions, all of which describe it as of uncertain significance, two stars, no conflict. In-silico predictions show benign computational verdict based on 8 benign predictions from BayesDel_addAF, DANN, DEOGEN2, EIGEN, LIST-S2, MVP, PrimateAI and SIFT vs 4 pathogenic predictions from FATHMM-MKL, M-CAP, MutationAssessor and MutationTaster and the position is not strongly conserved (CSH phyloP100way = 1.1 is less than 5). The tyrosine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. Therefore, it has been classified as a Variant of Uncertain Significance. -
