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.

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2022The p.N568K variant (also known as c.1704T>G), located in coding exon 11 of the BRIP1 gene, results from a T to G substitution at nucleotide position 1704. The asparagine at codon 568 is replaced by lysine, an amino acid with similar properties. One study detected this alteration in 2/13213 breast cancer cases and 0/5242 population controls (Easton DF et al. J. Med. Genet., 2016 05;53:298-309). 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. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
Familial cancer of breast;C1836860:Fanconi anemia complementation group J Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 02, 2023This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 568 of the BRIP1 protein (p.Asn568Lys). This variant is present in population databases (rs763458922, gnomAD 0.0009%). This missense change has been observed in individual(s) with breast cancer (PMID: 26921362). ClinVar contains an entry for this variant (Variation ID: 230476). 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. -
