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;C1836860:Fanconi anemia complementation group J Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Nov 06, 2023 | This sequence change creates a premature translational stop signal (p.Thr260Tyrfs*2) 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 not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with ovarian cancer (PMID: 26315354). This variant is also known as c.778insT, p.T260fs. ClinVar contains an entry for this variant (Variation ID: 461049). For these reasons, this variant has been classified as Pathogenic. - |
