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

The p.S116C variant (also known as c.347C>G), located in coding exon 3 of the BRIP1 gene, results from a C to G substitution at nucleotide position 347. The serine at codon 116 is replaced by cysteine, an amino acid with dissimilar properties. This variant was identified in a patient with breast cancer as part of a large Canadian cohort study of 2870 individuals (Bhai P et al. Front Genet, 2021 Jul;12:698595). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This missense variant replaces serine with cysteine at codon 116 of the BRIP1 protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with a familial cancer syndrome (PMID: 34326862). This variant has been identified in 4/282814 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. -

This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 116 of the BRIP1 protein (p.Ser116Cys). This variant is present in population databases (rs748793974, gnomAD 0.002%). This missense change has been observed in individual(s) with breast cancer (PMID: 34326862). ClinVar contains an entry for this variant (Variation ID: 187363). 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. -
