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

This sequence change creates a premature translational stop signal (p.Tyr822Leufs*10) 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 (no rsID available, gnomAD 0.1%). 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: 530329). For these reasons, this variant has been classified as Pathogenic. -

Breast Care Center, Daerim St. Mary`s Hospital

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The BRIP1:c.2464dupT variant was located in exon 17 of the BRIP1 gene, which predicts to lead to NMD (nonsense-mediated mRNA decay) and loss-of-function resulting from a frameshift. Its frequency is extremely low in gnomAD genomes/exomes. The previous classification in ClinVar is as a pathogenic variant. The patient is a 58-year-old Korean male diagnosed with papillary DCIS breast cancer. He has a family history of colon cancer in his mother, larynx, and pancreatic cancer in second-degree relatives on his paternal side. -
