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.

Hereditary cancer-predisposing syndrome

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Dec 20, 2021	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). One study detected this mutation in 0/3030 pancreatic cancer cases and 2/123136 population controls (Hu C et al. JAMA, 2018 06;319:2401-2409). 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	Jan 15, 2020	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. -

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. -
