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 18 ACMG points.
PVS1
?
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 411 pathogenic variants in the truncated region.
PM2
?
Very rare variant in population databases, with high coverage;
PP5
?
Variant 17-61861461-C-CA is Pathogenic according to our data. Variant chr17-61861461-C-CA is described in ClinVar as [Likely_pathogenic]. Clinvar id is 548896.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 06, 2018 | The c.78dupT pathogenic mutation, located in coding exon 1 of the BRIP1 gene, results from a duplication of T at nucleotide position 78, causing a translational frameshift with a predicted alternate stop codon (p.A27Cfs*42). 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. - |
Familial cancer of breast;C1836860:Fanconi anemia complementation group J Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 30, 2024 | This sequence change creates a premature translational stop signal (p.Ala27Cysfs*42) 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). ClinVar contains an entry for this variant (Variation ID: 548896). For these reasons, this variant has been classified as Pathogenic. - |
