Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.

The NM_032043.3(BRIP1):c.87G>T(p.Met29Ile) variant causes a missense change. The variant allele was found at a frequency of 0.00000481 in 1,455,648 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M29R) has been classified as Uncertain significance.

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.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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 variant was identified in prostate and pancreatic cancer patients, as well as, controls of Japanese ancestry (Momozawa Y et al. J Natl Cancer Inst, 2020 Apr;112:369-376; Mizukami K et al. EBioMedicine, 2020 Oct;60:103033). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. 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 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. -
