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

PP3_Moderate c.823C>T, located in exon 9 of the RAD51D gene, is predicted to result in the substitution of arginine by tryptophan at codon 275, p.(Arg275Trp). This variant is found in 4/268317 alleles at a frequency of 0.001% in the gnomAD v2.1.1 database, non-cancer dataset. The SpliceAI algorithm predicts no significant impact on splicing. The REVEL meta-predictor score for this variant (.794) suggests a deleterious effect on protein function according to Pejaver 2022 thresholds (PMID: 36413997) (PP3_Moderate). To our knowledge, no well-established functional studies have been reported for this variant. This variant has been reported in multiple cancer -affected individuals (PMID: 26261251 and data from our internal cohort of patients). This variant has been reported in the ClinVar database (8x uncertain significance) and in LOVD (2x uncertain significance). Based on currently available information, the variant c.823C>T should be considered an uncertain significance variant according to ACMG/AMP classification guidelines. -

The p.R275W variant (also known as c.823C>T), located in coding exon 9 of the RAD51D gene, results from a C to T substitution at nucleotide position 823. The arginine at codon 275 is replaced by tryptophan, an amino acid with dissimilar properties. This alteration was reported in one of 3429 women diagnosed with ovarian cancer and was not identified among 2772 controls in one study (Song H et al. J. Clin. Oncol., 2015 Sep;33:2901-7). 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 tryptophan at codon 275 of the RAD51D protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with ovarian cancer (PMID: 26261251). This variant has been identified in 4/251444 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. -

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 275 of the RAD51D protein (p.Arg275Trp). This variant is present in population databases (rs752780416, gnomAD 0.006%). This missense change has been observed in individual(s) with breast and/or ovarian cancer (PMID: 26261251, 35264596, 35534704). ClinVar contains an entry for this variant (Variation ID: 245669). 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. -
