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.

Uncertain:4

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Dec 18, 2023	This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 18 of the RAD51D protein (p.Gln18Arg). This variant is present in population databases (rs546225564, 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: 232535). 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. -

Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Nov 22, 2022	This missense variant replaces glutamine with arginine at codon 18 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. This variant has not been reported in individuals affected with RAD51D-related disorders in the literature. This variant has been identified in 7/247676 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. -

Variant summary: The RAD51D c.53A>G (p.Gln18Arg) variant involves the alteration of a non-conserved nucleotide. 3/3 in silico tools predict a benign outcome for this variant (SNPsandGO not captured due to low reliability index). This variant was found in 7/242658 control chromosomes, predominantly observed in the South Asian subpopulation at a frequency of 0.000227 (7/30774). This frequency is about 2 times higher than the estimated maximal expected allele frequency of a pathogenic RAD51D variant (0.000125), which might suggest that this is likely a benign polymorphism found primarily in the populations of South Asian origin. The variant of interest has not, to our knowledge, been reported in affected individuals via publications nor evaluated for functional impact by in vivo/vitro studies. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as uncertain significance. 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. -
