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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.E1202G variant (also known as c.3605A>G), located in coding exon 19 of the BRIP1 gene, results from an A to G substitution at nucleotide position 3605. The glutamic acid at codon 1202 is replaced by glycine, an amino acid with similar 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 1202 of the BRIP1 protein (p.Glu1202Gly). This variant is present in population databases (rs776010326, 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: 186352). 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) indicates that this missense variant is not expected to disrupt BRIP1 protein function with a negative predictive value of 95%. 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. -

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The BRIP1 c.3605A>G variant is predicted to result in the amino acid substitution p.Glu1202Gly. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.00088% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

KCCC/NGS Laboratory, Kuwait Cancer Control Center

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

a variant of uncertain significance was detected in the BRIP1 gene (c.3605A>G).This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non‐polar, at codon 1202 of the BRIP1 protein (p.Glu1202Gly). This amino acid position is not well conserved (PhyloP=1.6) . This variant is present in population databases (rs776010326, 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: 186352). In silico analysis supports that this missense variant does not alter protein structure/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. -
