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.

Jan 15, 2020

Color Diagnostics, LLC DBA Color Health

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant deletes 4 nucleotides in exon 4 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 2/251452 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 c.290_293delACAA pathogenic mutation, located in coding exon 3 of the BRIP1 gene, results from a deletion of 4 nucleotides at nucleotide positions 290 to 293, causing a translational frameshift with a predicted alternate stop codon (p.N97Mfs*3). This alteration has been reported in multiple ovarian cancer patients (Kanchi KL et al. Nat Commun, 2014;5:3156; Lu C et al. Nat Commun. 2015 Dec 22;6:10086; Arvai KJ et al. Hered Cancer Clin Pract, 2019 Jul;17:19). 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

The BRIP1 c.290_293del (p.Asn97Metfs*3) variant alters the translational reading frame of the BRIP1 mRNA and causes the premature termination of BRIP1 protein synthesis. This variant has been reported in the published literature individuals with ovarian cancer (PMID: 31341520 (2018)) and serous cystadenocarcinoma (PMID: 36451132 (2022)). This variant has also been reported in unaffected individuals (PMID: 33471991 (2021), see also LOVD (http://databases.lovd.nl/shared/genes/BRIP1)). Based on the available information, this variant is classified as pathogenic. The frequency of this variant in the general population, 0.000008 (2/251452 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is consistent with pathogenicity. -

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Asn97Metfs*3) 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 (rs763009188, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 187379). For these reasons, this variant has been classified as Pathogenic. -
