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.

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1853_1854insG pathogenic mutation, located in coding exon 12 of the BRIP1 gene, results from an insertion of one nucleotide at position 1853, causing a translational frameshift with a predicted alternate stop codon (p.P619Tfs*20). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). 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

This variant inserts 1 nucleotide in exon 13 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 1/251448 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. -

Review Status:no assertion criteria provided

Collection Method:clinical testing

The BRIP1 c.1853_1854insG variant is predicted to result in a frameshift and premature protein termination (p.Pro619Thrfs*20). This variant has been reported in at least one individual in a large ovarian cancer cohort (Table S7, Lilyquist et al. 2017. PubMed ID: 28888541). This variant is reported in 0.00088% of alleles in individuals of European (Non-Finnish) descent in gnomAD and is interpreted as likely pathogenic or pathogenic by multiple clinical laboratories in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/141753/). Frameshift variants in BRIP1 are expected to be pathogenic. This variant is interpreted as likely pathogenic. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Pro619Thrfs*20) 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 (rs587781985, gnomAD 0.0009%). 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: 141753). For these reasons, this variant has been classified as Pathogenic. -
