Breast-ovarian cancer, familial, susceptibility to, 4 Pathogenic:2
Likely pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Jan 04, 2024 | 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. - |
Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jun 27, 2023 | 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: 231839). Disruption of this splice site has been observed in individual(s) with ovarian cancer (PMID: 28888541). This variant is not present in population databases (gnomAD no frequency). This sequence change affects a donor splice site in intron 4 of the RAD51D 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 RAD51D are known to be pathogenic (PMID: 21822267). - |

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 04, 2023 | The c.345+2T>C intronic variant results from a T to C substitution two nucleotides after coding exon 4 in the RAD51D gene. This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice donor site. However, RNA studies have shown that exons 3 through 5 are excluded in several naturally occurring RAD51D isoforms (Davy G et al. Eur. J. Hum. Genet., 2017 10;25:1147-1154; Ambry internal data). Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
