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.

The p.R24S variant (also known as c.72G>T), located in coding exon 1 of the RAD51D gene, results from a G to T substitution at nucleotide position 72. The arginine at codon 24 is replaced by serine, an amino acid with dissimilar properties. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 24 of the RAD51D protein (p.Arg24Ser). This variant is present in population databases (rs28363257, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with RAD51D-related conditions. ClinVar contains an entry for this variant (Variation ID: 239401). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -
