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.

Color Diagnostics, LLC DBA Color Health

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This missense variant replaces arginine with glutamine at codon 300 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). To our knowledge, functional studies have not been reported for this variant. In a large international case-control study, this variant was reported in 4/60466 breast cancer cases and 5/53461 controls (PMID: 33471991). This variant has been identified in 6/251374 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: criteria provided, single submitter

Collection Method: clinical testing

The p.R300Q variant (also known as c.899G>A), located in coding exon 9 of the RAD51D gene, results from a G to A substitution at nucleotide position 899. The arginine at codon 300 is replaced by glutamine, an amino acid with highly similar properties. This alteration was detected in 2/5,589 German BRCA1/2-negative probands with breast cancer (Hauke J et al. Cancer Med, 2018 04;7:1349-1358). This alteration was detected in a cohort of 1663 Brazilian breast cancer patients who underwent hereditary multigene panel testing (Guindalini RSC et al. Sci Rep, 2022 Mar;12:4190). This variant was also reported in 4/60,466 breast cancer cases as well as 5/53,461 controls (Dorling et al. N Engl J Med. 2021 02;384:428-439). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. 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

Variant summary: The RAD51D c.899G>A (p.Arg300Gln) variant located in the DNA recombination and repair protein Rad51-like, C-terminal domain (via InterPro) involves the alteration of a conserved nucleotide and 3/4 in silico tools (SNPsandGO not captured due to low reliability index) predict a damaging outcome, although these predictions have yet to be functionally assessed. This variant was found in 2/121282 control chromosomes at a frequency of 0.0000165, which does not exceed the estimated maximal expected allele frequency of a pathogenic RAD51D variant (0.000125). In addition, multiple clinical diagnostic laboratories classified this variant as uncertain significance. The variant of interest has not, to our knowledge, been reported in affected individuals via publications. Because of the absence of clinical information and the lack of functional studies, the variant is classified as a "Variant of Uncertain Significance (VUS)," until additional information becomes available. -

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 300 of the RAD51D protein (p.Arg300Gln). This variant is present in population databases (rs761290755, gnomAD 0.005%). This missense change has been observed in individual(s) with breast and/or ovarian cancer (PMID: 29522266, 35264596). ClinVar contains an entry for this variant (Variation ID: 239405). 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 expected to disrupt RAD51D protein function with a positive 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. -
