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.

The c.1510dupA pathogenic mutation, located in coding exon 10 of the BRIP1 gene, results from a duplication of A at nucleotide position 1510, causing a translational frameshift with a predicted alternate stop codon (p.I504Nfs*7). This variant has been identified in multiple ovarian cancer cohorts (Koczkowska M et al. Cancers (Basel), 2018 Nov;10; Norquist BM et al. JAMA Oncol, 2016 Apr;2:482-90). 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. -

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

This variant inserts 1 nucleotide in exon 11 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 1/251366 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.Ile504Asnfs*7) 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 (rs775735278, gnomAD 0.006%). This premature translational stop signal has been observed in individual(s) with ovarian cancer (PMID: 26720728). This variant is also known as c.1510insA. ClinVar contains an entry for this variant (Variation ID: 230237). For these reasons, this variant has been classified as Pathogenic. -

The variant results in a shift of the reading frame, and is therefore predicted to result in the loss of a functional protein. Found in at least one patient with expected phenotype for this gene, and found in general population data at a frequency that is consistent with pathogenicity. -

Variant summary: BRIP1 c.1510dupA (p.Ile504AsnfsX7) results in a premature termination codon, predicted to cause absence of the protein due to nonsense mediated decay, which is a commonly known mechanism for disease. The variant allele was found at a frequency of 4e-06 in 251366 control chromosomes. c.1510dupA has been reported in the literature in at-least one individual affected with Breast Cancer (e.g. Weber-Lassalle_2018). 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: 29368626). ClinVar contains an entry for this variant (Variation ID: 230237). Based on the evidence outlined above, the variant was classified as pathogenic. -
