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.

The p.M29I variant (also known as c.87G>T), located in coding exon 1 of the BRIP1 gene, results from a G to T substitution at nucleotide position 87. The methionine at codon 29 is replaced by isoleucine, an amino acid with highly similar properties. This alteration has been reported with a carrier frequency of 0.00092 in 7636 unselected prostate cancer patients and 0.00089 in 12366 male controls of Japanese ancestry (Momozawa Y et al. J. Natl. Cancer Inst., 2020 04;112:369-376). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This sequence change replaces methionine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 29 of the BRIP1 protein (p.Met29Ile). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with prostate cancer (PMID: 31214711). ClinVar contains an entry for this variant (Variation ID: 483161). 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. -
