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:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

BP4, BP7 c.672A>G, located in exon 7 of the BRIP1 gene, is predicted to result in no amino acid change, p.(Gly224=)(BP7). This variant is found in 3/35090, with a filter allele frequency of 0.001% at 99% confidence in the gnomAD v2.1.1 database (Latino non-cancer data set). The SpliceAI algorithm predicts no significant impact on splicing (BP4). To our knowledge, neither relevant clinical data nor functional studies have been reported for this variant. This variant has been reported in the ClinVar database (1x benign, 5x likely benign) but is not present in LOVD database. Based on currently available information, the variant c.672A>G is classified as a likely benign variant according to ACMG guidelines.

The BRIP1 c.672A>G (p.Gly224=) synonymous variant has not been reported in individuals with BRIP1-related conditions in the published literature. The frequency of this variant in the general population, 0.000087 (3/34574 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using software algorithms for the prediction of the effect of nucleotide changes on splicing yielded predictions that this variant does not affect BRIP1 mRNA splicing. Based on the available information, we are unable to determine the clinical significance of this variant.

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

Variant summary: BRIP1 c.672A>G alters a non-conserved nucleotide resulting in a synonymous change. The observed variant frequency within African control individuals in the gnomAD database is approximately 2.08 fold above the estimated maximal expected allele frequency for a pathogenic variant in BRIP1 causing Hereditary Breast and Ovarian Cancer phenotype (6.3e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African origin. To our knowledge, no occurrence of c.672A>G in individuals affected with Hereditary Breast and Ovarian Cancer and no experimental evidence demonstrating its impact on protein function have been reported. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as likely benign.
