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.

Pathogenic:3

Pathogenic, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	May 10, 2023	This variant inserts 2 nucleotides in exon 14 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. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with breast and ovarian cancer (PMID: 25452441, 26315354, 26681312, 26845104, 26921362, 33471991) as well as in unaffected individuals (PMID: 30254378, 33471991). This variant has not been identified 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. -

Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Aug 03, 2021	The c.2038_2039dupTT pathogenic mutation, located in coding exon 13 of the BRIP1 gene, results from a duplication of TT at nucleotide position 2038, causing a translational frameshift with a predicted alternate stop codon (p.L680Ffs*9). This mutation has been reported in multiple breast and/or ovarian cancer patients (Ramus SJ et al. J Natl Cancer Inst, 2015 Nov;107; Couch FJ et al. J Clin Oncol, 2015 Feb;33:304-11; Shirts BH et al. Genet Med, 2016 10;18:974-81; Easton DF et al. J Med Genet, 2016 05;53:298-309; Susswein LR et al. Genet Med, 2016 08;18:823-32; Dorling et al. N Engl J Med. 2021 02;384:428-439), and has also been detected in healthy individuals undergoing multigene panel testing (Sulem P et al. Nat Genet, 2015 May;47:448-52; Rowley SM et al. Genet Med, 2019 04;21:913-922; Dorling et al. N Engl J Med. 2021 02;384:428-439). 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. -

This sequence change creates a premature translational stop signal (p.Leu680Phefs*9) 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 not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with breast or ovarian cancer (PMID: 21964575, 25452441, 26315354, 26681312, 26845104). This variant is also known as c.2040_ 2041insTT. ClinVar contains an entry for this variant (Variation ID: 128166). For these reasons, this variant has been classified as Pathogenic. -
