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, criteria provided, single submitter	clinical testing	GeneDx	Apr 19, 2019	Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Not observed at a significant frequency in large population cohorts (Lek 2016); This variant is associated with the following publications: (PMID: 26681312, 26296696, 29338689, 32566746, 31742824) -
Pathogenic, criteria provided, single submitter	clinical testing	Quest Diagnostics Nichols Institute San Juan Capistrano	Jun 30, 2023	The BRIP1 c.1066C>T (p.Arg356*) variant is predicted to cause the premature termination of BRIP1 protein synthesis. This variant has been reported in the published literature in individuals with breast and/or ovarian cancer (PMIDs: 33471991 (2021) see also LOVD (https://databases.lovd.nl/shared/variants/BRIP1), 31742824 (2020), 32566746 (2020), 30982232 (2018), 29338689 (2018), 28888541 (2017), 28495237 (2017), 26681312 (2015)), pancreatic cancer (PMID: 35171259 (2022)), lung cancer (PMID: 35273153 (2022)), and astrocytomas (PMID: 34308104 (2021)). The frequency of this variant in the general population, 0.000011 (3/282716 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is consistent with pathogenicity. Based on the available information, this variant is classified as pathogenic. -

Hereditary cancer-predisposing syndrome

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Nov 19, 2024	The p.R356* pathogenic mutation (also known as c.1066C>T), located in coding exon 7 of the BRIP1 gene, results from a C to T substitution at nucleotide position 1066. This changes the amino acid from an arginine to a stop codon within coding exon 7. This alteration has been identified in several individuals with a personal and/or family history of breast and/or ovarian cancer (Susswein LR et al. Genet. Med. 2016 Aug;18:823-32; Frey MK et al. Gynecol. Oncol. 2017 Jul;146:123-128; Park JS et al. BMC Cancer 2018 01;18(1):83; Wang J et al. Cancer Med, 2019 05;8:2074-2084; Kaneyasu T et al. NPJ Breast Cancer, 2020 Jun;6:25; Shao D et al. Cancer Sci, 2020 Feb;111:647-657). 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. -
Pathogenic, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Dec 13, 2022	This variant changes 1 nucleotide in exon 8 of the BRIP1 gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been reported in individuals affected with breast and/or ovarian cancer (PMID: 26296696, 26681312, 28495237, 32566746). This variant has been identified in 3/282716 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. -

Hereditary breast ovarian cancer syndrome

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Nov 03, 2022	The p.Arg356X variant in BRIP1 has been reported in > 4 individuals affected with breast and or ovarian cancer (selected references: Susswein 2016 PMID: 26681312, Frey 2017 PMID: 28495237, Kaneyasu 2020 PMID: 32566746, Shao 2020 PMID: 31742824, Park 2018 29338689) and in ClinVar (Variation ID 182345). It was identified in 1/5200 East Asian chromosomes by gnomAD (http://gnomad.broadinstitute.org). This nonsense variant leads to a premature termination codon at position 356, which is predicted to lead to a truncated or absent protein. Loss of function of the BRIP1 gene is an established disease mechanism in autosomal dominant breast and ovariant cancer. In summary, this variant meets criteria to be classified as pathogenic for autosomal dominant breast and ovarian cancer. ACMG/AMP Criteria applied: PVS1, PS4_Supporting, PM2_Supporting. -

This sequence change creates a premature translational stop signal (p.Arg356*) 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 (rs730881633, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with breast cancer (PMID: 26681312, 28495237). ClinVar contains an entry for this variant (Variation ID: 182345). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
