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 sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 666 of the BRIP1 protein (p.Asn666Asp). This variant is present in population databases (rs765816425, gnomAD 0.006%). This missense change has been observed in individual(s) with prostate cancer (PMID: 31214711). ClinVar contains an entry for this variant (Variation ID: 929547). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt BRIP1 protein function with a negative predictive value of 80%. 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. -

The p.N666D variant (also known as c.1996A>G), located in coding exon 13 of the BRIP1 gene, results from an A to G substitution at nucleotide position 1996. The asparagine at codon 666 is replaced by aspartic acid, an amino acid with highly similar properties. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
