Ambry Genetics RCV001013114 SCV001173656 likely pathogenic Hereditary cancer-predisposing syndrome 2019-09-23 criteria provided, single submitter clinical testing The c.1795-1G>A intronic variant results from a G to A substitution one nucleotide upstream from coding exon 12 of the BRIP1 gene. This nucleotide position is highly conserved in available vertebrate species. Using the BDGP and ESEfinder splice site prediction tools, this alteration is predicted to weaken the efficiency of the native splice acceptor site; however, direct evidence is unavailable. Alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay. As such, this alteration is classified as likely pathogenic.
Invitae RCV002551764 SCV003314424 likely pathogenic Familial cancer of breast; Fanconi anemia complementation group J 2023-01-10 criteria provided, single submitter clinical testing 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: 820059). 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 12 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).
