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.

ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 12 ACMG points.
PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.087733336 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 17-61686166-C-A is Pathogenic according to our data. Variant chr17-61686166-C-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 936533.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Likely pathogenic, criteria provided, single submitter | clinical testing | Baylor Genetics | Sep 29, 2023 | - - |
Likely pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Jun 07, 2023 | This variant is considered likely pathogenic. This variant occurs within a consensus splice junction and is predicted to result in abnormal mRNA splicing of either an out-of-frame exon or an in-frame exon necessary for protein stability and/or normal function. - |
Familial cancer of breast;C1836860:Fanconi anemia complementation group J Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jul 17, 2022 | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 936533). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change affects an acceptor splice site in intron 18 of the BRIP1 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in BRIP1 are known to be pathogenic (PMID: 16116423, 17033622, 21964575). - |
