Genes affected

RAD51D (HGNC:9823): (RAD51 paralog D) The protein encoded by this gene is a member of the RAD51 protein family. RAD51 family members are highly similar to bacterial RecA and Saccharomyces cerevisiae Rad51, which are known to be involved in the homologous recombination and repair of DNA. This protein forms a complex with several other members of the RAD51 family, including RAD51L1, RAD51L2, and XRCC2. The protein complex formed with this protein has been shown to catalyze homologous pairing between single- and double-stranded DNA, and is thought to play a role in the early stage of recombinational repair of DNA. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the downstream ring finger and FYVE-like domain containing 1 (RFFL) gene.

This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 207 of the RAD51D protein (p.Ser207Pro). This variant is present in population databases (rs372365287, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with RAD51D-related conditions. ClinVar contains an entry for this variant (Variation ID: 229719). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on RAD51D protein function. This variant disrupts the p.Ser207 amino acid residue in RAD51D. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 21822267, 22986143, 26845104, 26976419, 28646019). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

A likely pathogenic mutation was detected in the RAD51D gene (c.283T>C). This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 95 of the RAD51D protein (p.Ser95Pro). This variant is present in population databases (rs372365287, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with RAD51D-related conditions. ClinVar contains an entry for this variant (Variation ID: 229719). Computational prediction suggests that this variant may have deleterious impact on protein structure and function . This variant disrupts the p.Ser95 amino acid residue in RAD51D. A different variant affecting the same codon position (p.Ser95Leu) is considered to be disease-causing (ClinVar variation ID: 142102), suggesting that serine at this position is important for protein structure and function (PMID: 21822267, 22986143, 26845104, 26976419, 28646019). 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. Pathogenic mutations in the RAD51D gene are associated with Breast-ovarian cancer, familial, susceptibility to, 4 (OMIM 614291 ).

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This missense variant replaces serine with proline at codon 207 in the ATPase domain of the RAD51D protein. The RAD51D ATPase motif is required for resistance to DNA cross-linking agents and for interaction with RAD51C in homologous recombination (PMID: 16236763). This variant is located in the conserved Walker B motif that contributes a glutamic acid residue hydrolyzing ATP in the ATPase domain (PMID: 27941862, 37344587). This variant substitutes the conserved serine (residue 207) adjacent to the catalytic glutamic acid (residue 206) to proline in the RAD51D ATPase domain. Computational prediction suggests that this variant may have deleterious impact on protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with pancreatic ductal adenocarcinoma (PMID: 32255556). This variant has been identified in 3/282824 chromosomes in the general population by the Genome Aggregation Database (gnomAD). A different variant affecting the same codon (p.Ser207Leu) is considered to be disease-causing (ClinVar Variation ID: 142102), suggesting that serine at this position is important for protein structure and function. Although there is a suspicion that this variant may be associated with disease, additional studies are necessary to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.S207P variant (also known as c.619T>C), located in coding exon 7 of the RAD51D gene, results from a T to C substitution at nucleotide position 619. The serine at codon 207 is replaced by proline, an amino acid with similar properties. This variant was identified in 1/177 individuals with pancreatic ductal adenocarcinoma undergoing multi-gene panel testing (Cremin C et al. Cancer Med, 2020 Jun;9:4004-4013). This variant was also identified in a cohort of 376 women with breast cancer (Osler TS et al. Breast Cancer Res Treat, 2025 Apr;210:477-486). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear.
