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.

Collection Method:clinical testing

The p.S62L variant (also known as c.185C>T), located in coding exon 3 of the RAD51D gene, results from a C to T substitution at nucleotide position 185. The serine at codon 62 is replaced by leucine, an amino acid with dissimilar properties. In one study, this variant was detected in 1/911 patients from families with breast and/or ovarian cancer and was not seen in 1060 population controls from the United Kingdom (Loveday C et al. Nat. Genet., 2011 Aug;43:879-882). In another study, this variant was not detected in 3429 patients with invasive epithelial ovarian cancer, but was reported in 1/2772 controls (Song H et al. J. Clin. Oncol. 2015 Sep;33:2901-7). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -

This missense variant replaces serine with leucine at codon 62 of the RAD51D protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). In a mini-gene RNA splicing study, this variant has been shown to result in a significant proportion of full-length transcripts (PMID: 34200360). This variant has been reported in an individual affected with breast and/or ovarian cancer (PMID: 21822267) and in an unaffected individual in an ovarian cancer risk case-control study (PMID: 26261251). This variant has been identified in 6/282720 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

The RAD51D c.185C>T (p.Ser62Leu) variant has been reported in the published literature in individuals/families affected with breast and/or ovarian cancer (PMIDs: 21822267 (2011), 34923718 (2022)), as well as in reportedly healthy individuals (PMID: 26261251 (2015)). The frequency of this variant in the general population, 0.000046 (6/129096 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded conflicting predictions that this variant is benign or damaging. Based on the available information, we are unable to determine the clinical significance of this variant. -

In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Minigene assay demonstrates slightly increased amount of alternatively spliced transcripts, but the clinical significance is unclear (Bueno-Martinez et al., 2021); This variant is associated with the following publications: (PMID: 26261251, 27720647, 14704354, 19327148, 34923718, 21822267, 34200360) -

This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 62 of the RAD51D protein (p.Ser62Leu). This variant is present in population databases (rs374357106, gnomAD 0.005%). This missense change has been observed in individual(s) with breast and/or ovarian cancer (PMID: 21822267). ClinVar contains an entry for this variant (Variation ID: 185036). 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) indicates that this missense variant is not expected to disrupt RAD51D protein function with a negative predictive value of 80%. 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. -

Variant summary: RAD51D c.185C>T (p.Ser62Leu) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2.3e-05 in 261166 control chromosomes (gnomAD and publication data). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.185C>T has been reported in the literature in individuals affected with Hereditary Breast And Ovarian Cancer Syndrome (Loveday_2011, Boni_2021). These reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Six ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

The RAD51D c.185C>T variant is predicted to result in the amino acid substitution p.Ser62Leu. This variant has been reported in individuals with breast and/or ovarian cancer (Table S4, Loveday et al. 2011. PubMed ID: 21822267; Table A4, Song et al. 2015. PubMed ID: 26261251; Bueno-Martínez et al. 2021. PubMed ID: 34200360). This variant is reported in 0.0046% of alleles in individuals of European (Non-Finnish) descent in gnomAD, and it has been interpreted as a variant of uncertain significance in the ClinVar database (https://www.ncbi.nlm.nih.gov/clinvar/variation/185036/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
