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.

Variant summary: The RAD51D c.434G>A (p.Arg145His) variant located in the P-loop containing nucleoside triphosphate hydrolase and C-terminal domain (via InterPro) causes a missense change involving a conserved nucleotide, which 4/4 in silico tools (SNPs&Go not captured here due to low reliability index) predict a "damaging" outcome, although these predictions have yet to be functionally assessed. The variant of interest was observed in the large, broad control population, ExAC, with an allele frequency of 6/121410 (1/20242), which does not exceed the estimated maximal expected allele frequency for a pathogenic RAD51D variant of 1/8000. One clinical diagnostic laboratory has classified this variant as uncertain significance. The variant of interest has been reported in at least one patient sample referred for NGS-based multigene hereditary-cancer testing without strong evidence for causality (Mu_2016). Taken together, the variant is classified as a variant of uncertain significance (VUS), until additional information becomes available. -

The p.R145H variant (also known as c.434G>A), located in coding exon 5 of the RAD51D gene, results from a G to A substitution at nucleotide position 434. The arginine at codon 145 is replaced by histidine, an amino acid with highly similar properties. This variant was identified in a cohort of 3,579 African males diagnosed with prostate cancer who underwent multi-gene panel testing of 19 DNA repair and cancer predisposition genes (Matejcic M et al. JCO Precis Oncol, 2020 Jan;4:32-43). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This missense variant replaces arginine with histidine at codon 145 of the RAD51D protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been performed for this variant. This variant has been reported in an individual affected with breast cancer (PMID: 30111881). In a large breast cancer case-control study, this variant was identified in 2/60464 cases and 1/53460 controls - OR=1.768 (95%CI 0.16 to 19.503); p-value=1 (PMID: 33471991 - Leiden Open Variation Database DB-ID RAD51D_000140). This variant has also been identified in 16/282828 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. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 145 of the RAD51D protein (p.Arg145His). This variant is present in population databases (rs147264215, gnomAD 0.05%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with RAD51D-related disease (PMID: 30111881). ClinVar contains an entry for this variant (Variation ID: 187149). 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. 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. -

The RAD51D c.434G>A variant is predicted to result in the amino acid substitution p.Arg145His. This variant has been reported as uncertain in a study of Greek patients with breast and ovarian cancer (Konstanta et al. 2018. PubMed ID: 30111881). This variant is reported in 0.056% of alleles in individuals of African descent in gnomAD and has been interpreted as variant of uncertain significance in the ClinVar database (https://www.ncbi.nlm.nih.gov/clinvar/variation/187149/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
