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.

Variant summary: BRIP1 c.2273dupT (p.Ala759SerfsX6) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory (c.2392C>T, p.Arg798X; c.2400C>G, p.Tyr800X). The variant allele was found at a frequency of 8e-06 in 251216 control chromosomes (gnomAD). c.2273dupT has been reported in the literature in individuals affected with endometrial, prostate, ovarian or breast cancer (Susswein_2016, Pritchard_2016, Weber-Lassalle_2018). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Five 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 pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

The c.2273dupT pathogenic mutation, located in coding exon 15 of the BRIP1 gene, results from a duplication of T at nucleotide position 2273, causing a translational frameshift with a predicted alternate stop codon (p.A759Sfs*6). This alteration has been identified in individuals diagnosed with breast, ovarian and/or prostate cancer (Pritchard CC et al. N. Engl. J. Med. 2016 Aug;375:443-53; Weber-Lassalle N et al. Breast Cancer Res, 2018 01;20:7; Dorling et al. N Engl J Med. 2021 02;384:428-43) and in 1/10030 consecutive patients referred for evaluation by an NGS hereditary cancer panel (Susswein LR et al. Genet. Med. 2016 08;18:823-32). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -

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

This variant inserts 1 nucleotide in exon 16 of the BRIP1 gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been identified in 2/251216 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of BRIP1 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. -

This sequence change creates a premature translational stop signal (p.Ala759Serfs*6) in the BRIP1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BRIP1 are known to be pathogenic (PMID: 16116423, 17033622, 21964575). This variant is present in population databases (rs587780236, gnomAD 0.002%). This premature translational stop signal has been observed in individual(s) with prostate cancer (PMID: 26681312, 27433846, 29368626). ClinVar contains an entry for this variant (Variation ID: 128170). For these reasons, this variant has been classified as Pathogenic. -
