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 submitter	clinical testing	Quest Diagnostics Nichols Institute San Juan Capistrano	Apr 11, 2018	- -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Jun 25, 2015	This variant is denoted BRIP1 c.1873T>C at the cDNA level, p.Ser625Pro (S625P) at the protein level, and results in the change of a Serine to a Proline (TCA>CCA). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. BRIP1 Ser625Pro was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Since Serine and Proline differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. BRIP1 Ser625Pro occurs at a position that is conserved across species and is located in the helicase domain (Cantor 2011). In silico analyses predict that this variant is probably damaging to protein structure and function. Based on currently available information, it is unclear whether BRIP1 Ser625Pro is pathogenic or benign. We consider it to be a variant of uncertain significance. -

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Mar 30, 2022	The p.S625P variant (also known as c.1873T>C), located in coding exon 12 of the BRIP1 gene, results from a T to C substitution at nucleotide position 1873. The serine at codon 625 is replaced by proline, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. 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	Apr 14, 2023	This missense variant replaces serine with proline at codon 625 of the BRIP1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with BRIP1-related disorders in the literature. This variant has been identified in 1/251450 chromosomes 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. -

This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 625 of the BRIP1 protein (p.Ser625Pro). This variant is present in population databases (no rsID available, gnomAD 0.0009%). 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: 419290). 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 with a positive 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 BRIP1 c.1873T>C; p.Ser625Pro variant (rs935011040), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 419290). This variant is only observed on one allele in the Genome Aggregation Database, indicating it is not a common polymorphism. The serine at codon 625 is highly conserved, and computational analyses (SIFT, PolyPhen-2) predict that this variant is deleterious. However, given the lack of clinical and functional data, the significance of this variant is uncertain at this time. -
