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 GeneticsJun 05, 2023The p.S1032R variant (also known as c.3096T>G), located in coding exon 19 of the BRIP1 gene, results from a T to G substitution at nucleotide position 3096. The serine at codon 1032 is replaced by arginine, an amino acid with dissimilar properties. 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. -

BRIP1-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesApr 27, 2023The BRIP1 c.3096T>G variant is predicted to result in the amino acid substitution p.Ser1032Arg. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. It is interpreted as uncertain significance by the majority of submitters in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/185090/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingGeneDxJun 19, 2017This variant is denoted BRIP1 c.3096T>G at the cDNA level, p.Ser1032Arg (S1032R) at the proteinlevel, and results in the change of a Serine to an Arginine (AGT>AGG). This variant has not, to our knowledge, beenpublished in the literature as pathogenic or benign. BRIP1 Ser1032Arg was not observed at a significant allelefrequency in large population cohorts (NHLBI Exome Sequencing Project, The 1000 Genomes Consortium 2015, Lek2016). Since Serine and Arginine differ in some properties, this is considered a semi-conservative amino acidsubstitution. BRIP1 Ser1032Arg occurs at a position that is not conserved and is located within the BRCA1 bindingdomain (Cantor 2011). In silico analyses predict that this variant is unlikely to alter protein structure or function. Basedon currently available evidence, it is unclear whether BRIP1 Ser1032Arg is a pathogenic or benign variant. Weconsider it to be a variant of uncertain significance. -
