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 GeneticsOct 12, 2023The p.S1117A variant (also known as c.3349T>G), located in coding exon 19 of the BRIP1 gene, results from a T to G substitution at nucleotide position 3349. The serine at codon 1117 is replaced by alanine, an amino acid with similar properties. This alteration was detected in a cohort of 381 unselected endometrial cancer patients, who underwent multi-gene panel testing (Ring KL et al. Mod. Pathol. 2016 Nov;29:1381-1389). 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. -
Uncertain significance, criteria provided, single submitterclinical testingColor Diagnostics, LLC DBA Color HealthNov 22, 2019This missense variant replaces serine with alanine at codon 1117 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). Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional studies have not been performed for this variant. This variant has been reported in an individual affected with endometrial cancer (PMID: 27443514). This variant has also been identified in 6/250850 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. -
Familial cancer of breast;C1836860:Fanconi anemia complementation group J Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 08, 2022This sequence change replaces serine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 1117 of the BRIP1 protein (p.Ser1117Ala). This variant is present in population databases (rs779860140, gnomAD 0.01%). This missense change has been observed in individual(s) with endometrial cancer (PMID: 27443514). ClinVar contains an entry for this variant (Variation ID: 185199). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
