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.

This variant is denoted RAD51D c.4G>T at the cDNA level, p.Gly2Cys (G2C) at the protein level, and results in the change of a Glycine to a Cysteine (GGC>TGC). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. RAD51D Gly2Cys was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Glycine and Cysteine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. RAD51D Gly2Cys occurs at a position where amino acids with properties similar to Glycine are tolerated across species and is located in the region that preferentially binds ssDNA (Kim 2011, UniProt). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. This variant occurs in a conserved nucleotide in the Kozak consensus sequence and therefore may impact protein translation; however, in the absence of functional studies, the actual effect of this variant is unknown. Based on currently available evidence, it is unclear whether RAD51D Gly2Cys is pathogenic or benign. We consider it to be a variant of uncertain significance. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with cysteine, which is neutral and slightly polar, at codon 2 of the RAD51D protein (p.Gly2Cys). This variant is present in population databases (rs372082751, gnomAD 0.0009%). 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: 421161). 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 disruptive. 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. -
