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:3

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 27, 2023	The p.L385M variant (also known as c.1153C>A), located in coding exon 8 of the BRIP1 gene, results from a C to A substitution at nucleotide position 1153. The leucine at codon 385 is replaced by methionine, an amino acid with highly similar properties. 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Mar 28, 2023	This missense variant replaces leucine with methionine at codon 385 of the BRIP1 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with breast cancer (PMID: 29368626). This variant has not been identified 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	Institute for Biomarker Research, Medical Diagnostic Laboratories, L.L.C.	Aug 20, 2024	The missense variant NM_032043.3(BRIP1):c.1153C>A (p.Leu385Met) has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.Leu385Met variant is novel (not in any individuals) in gnomAD. The p.Leu385Met variant is novel (not in any individuals) in 1kG. The p.Leu385Met missense variant is predicted to be damaging by both SIFT and PolyPhen2. The leucine residue at codon 385 of BRIP1 is conserved in all mammalian species. The nucleotide c.1153 in BRIP1 is predicted conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance -

This sequence change replaces leucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 385 of the BRIP1 protein (p.Leu385Met). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 216783). 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 expected to disrupt 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. -
