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.

Familial cancer of breast Pathogenic:2
Likely pathogenic, criteria provided, single submitterclinical testingBaylor GeneticsJan 31, 2024- -
Pathogenic, criteria provided, single submitterclinical testingMyriad Genetics, Inc.Jun 02, 2023This variant is considered pathogenic. This variant creates a frameshift predicted to result in premature protein truncation. -
Familial cancer of breast;C1836860:Fanconi anemia complementation group J Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingInvitaeFeb 04, 2022For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 530301). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change creates a premature translational stop signal (p.Met532Asnfs*4) 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). -
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsSep 26, 2019The c.1594dupA pathogenic mutation, located in coding exon 10 of the BRIP1 gene, results from a duplication of A at nucleotide position 1594, causing a translational frameshift with a predicted alternate stop codon (p.M532Nfs*4). 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. -
