RCV001036684 | SCV001200061 | likely pathogenic | Breast-ovarian cancer, familial, susceptibility to, 4 | 2019-12-11 | 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. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in RAD51D are known to be pathogenic (PMID: 21822267). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with RAD51D-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change affects an acceptor splice site in intron 1 of the RAD51D gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. |
Ambry Genetics | RCV003372940 | SCV004096114 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-07-19 | criteria provided, single submitter | clinical testing | The c.83-2A>G intronic variant results from an A to G substitution two nucleotides upstream from coding exon 2 in the RAD51D gene. This nucleotide position is highly conserved in available vertebrate species. Alterations that disrupt the canonical splice site are expected to result in aberrant splicing. In silico splice site analysis predicts that this alteration may result in the creation or strengthening of a novel splice acceptor site; however, direct evidence is insufficient at this time (Ambry internal data). The resulting transcript is predicted to be in-frame and is not expected to trigger nonsense-mediated mRNAdecay. The exact functional effect of the altered amino acid sequence is unknown. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
