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.

Likely pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpAug 03, 2018Variant summary: BRIP1 c.1240C>T (p.Gln414X) 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. Truncations downstream of this position have been classified as pathogenic by our laboratory (eg. c.1871C>A (p.Ser624X), c.2255_2256delAA (p.Lys752fsX12), c.2392C>T (p.Arg798X)). The variant allele was found at a frequency of 4.1e-06 in 245868 control chromosomes (gnomAD). The variant, c.1240C>T, has been reported in the literature with limited information (Hu_2018, La Duca_2017). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four ClinVar submissions from clinical diagnostic laboratories (evaluation after 2014) cite the variant as "likely pathogenic/pathogenic." Based on the evidence outlined above, the variant was classified as likely pathogenic. -

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 06, 2023This sequence change creates a premature translational stop signal (p.Gln414*) 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 (rs368796923, 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: 141382). For these reasons, this variant has been classified as Pathogenic. -
Hereditary cancer-predisposing syndrome Pathogenic:2
Pathogenic, criteria provided, single submitterclinical testingColor Diagnostics, LLC DBA Color HealthFeb 02, 2022This variant changes 1 nucleotide in exon 9 of the BRIP1 gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. To our knowledge, this variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 1/251108 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. -
Pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsNov 01, 2021The p.Q414* pathogenic mutation (also known as c.1240C>T), located in coding exon 8 of the BRIP1 gene, results from a C to T substitution at nucleotide position 1240. This changes the amino acid from a glutamine to a stop codon within coding exon 8. This variant has been identified in at least one patient with a personal and family history of breast and/or ovarian cancer (Maxwell KN et al. Am J Hum Genet. 2016 May;98:801-817). 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. -

BRIP1-associated familial cancer predisposition Pathogenic:1
Likely pathogenic, criteria provided, single submitterclinical testingRady Children's Institute for Genomic Medicine, Rady Children's Hospital San Diego-This nonsense variant found in exon 9 of 20 is predicted to result in loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. This variant has not been reported in affected individuals in the literature to our knowledge; however, loss-of-function variation in BRIP1 is an established mechanism of disease (PMID: 16116423, 17033622, 21964575). The c.1240C>T (p.Gln414Ter) variant is present in the heterozygous state in the gnomAD population database at a frequency of 0.0004% (1/251108) and thus presumed to be rare. Based on the available evidence, the c.1240C>T (p.Gln414Ter) variant is classified as Likely Pathogenic. -
