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.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 275 of the RAD51D protein (p.Arg275Gln). This variant is present in population databases (rs368914740, gnomAD 0.0009%). This missense change has been observed in individual(s) with breast cancer and/or prostate cancer (PMID: 32658311, 32832836). ClinVar contains an entry for this variant (Variation ID: 185774). 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The RAD51D c.824G>A (p.Arg275Gln) variant has been reported in the published literature in an individual with breast cancer (PMID: 32658311 (2011)). This variant has also been identified in a cohort of individuals with prostate cancer and reportedly healthy individuals (PMID: 32832836 (2020)). The frequency of this variant in the general population, 0.000004 (1/251444 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.R275Q variant (also known as c.824G>A), located in coding exon 9 of the RAD51D gene, results from a G to A substitution at nucleotide position 824. The arginine at codon 275 is replaced by glutamine, an amino acid with highly similar properties. 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This missense variant replaces arginine with glutamine at codon 275 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 reported for this variant. This variant has not been reported in individuals affected with RAD51D-related disorders in the literature. This variant has been identified in 1/251444 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. -

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The RAD51D c.824G>A variant is predicted to result in the amino acid substitution p.Arg275Gln. This variant has been reported in a Turkish individual with breast cancer and in a male with prostate cancer of African ancestry (Table S6. Akcay et al. 2020. PubMed ID: 32658311; Table S2. Matejcic et al. 2020. PubMed ID: 32832836). This variant is reported in 0.00088% of alleles in individuals of European (Non-Finnish) descent in gnomAD and is classified as a variant of uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/185774/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
