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.

Review Status:criteria provided, single submitter

This sequence change creates a premature translational stop signal (p.Glu45*) 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). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This premature translational stop signal has been observed in individual(s) with hereditary cancer (PMID: 24763289). ClinVar contains an entry for this variant (Variation ID: 140808). RNA analysis performed to evaluate the impact of this premature translational stop signal on mRNA splicing indicates it does not significantly alter splicing (internal data). For these reasons, this variant has been classified as Pathogenic. -

The BRIP1 p.Glu45* variant was identified in 2 of 10630 proband chromosomes (frequency: 0.0002) from individuals or families with hereditary breast and ovarian cancer and was not identified in 6862 control chromosomes from healthy individuals (LaDuca 2014, Ramus 2015). The variant was also identified in dbSNP (ID: rs587781292) as "Pathogenic", ClinVar (as pathogenic by Ambry Genetics, Invitae, and GeneDx), and Cosmic databases. The variant was not identified in the MutDB and Zhejiang Colon Cancer Database. The variant was identified in control databases in 1 of 30980 chromosomes at a frequency of 0.00003 (Genome Aggregation Database Feb 27, 2017), in the European population in 1 of 15010 chromosomes (freq: 0.00007); but not in in the African, Other, Latino, Ashkenazi Jewish, East Asian, Finnish, o South Asian populations. The p.Glu45* variant leads to a premature stop codon at position 45 which is predicted to lead to a truncated or absent protein and loss of function. Loss of function variants of the BRIP1 gene are an established mechanism of disease in hereditary breast and ovarian cancer and is the type of variant expected to cause the disorder. In summary, based on the above information this variant meets our laboratory’s criteria to be classified as pathogenic. -

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

This variant changes 1 nucleotide in exon 3 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 an individual affected with ovarian cancer (PMID: 26315354) and an individual suspected to be affected with hereditary breast and ovarian cancer (PMID: 24763289). This variant also has been detected in a breast cancer case-control meta-analysis in 2/53461 unaffected individuals and absent in 60466 cases (PMID: 33471991; Leiden Open Variation Database DB-ID BRIP1_000746). This variant has also been identified in 2/282808 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. -

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

The p.E45* pathogenic mutation (also known as c.133G>T), located in coding exon 2 of the BRIP1 gene, results from a G to T substitution at nucleotide position 133. This changes the amino acid from a glutamic acid to a stop codon within coding exon 2. In one study, this alteration was observed in 1/3236 cases with invasive epithelial ovarian cancer and 0/3431 controls (Ramus SJ et al. J. Natl. Cancer Inst. 2015 Nov;107). 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. -

Variant summary: BRIP1 c.133G>T (p.Glu45X) 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. The variant allele was found at a frequency of 4e-06 in 251404 control chromosomes. c.133G>T has been reported in the literature in individuals affected with BRIP1 related Breast and/or Ovarian Cancer (example, Ramus_2015). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 26315354). ClinVar contains an entry for this variant (Variation ID: 140808). Based on the evidence outlined above, the variant was classified as pathogenic. -
