Genes affected

RAD51C (HGNC:9820): (RAD51 paralog C) This gene is a member of the RAD51 family. RAD51 family members are highly similar to bacterial RecA and Saccharomyces cerevisiae Rad51 and are known to be involved in the homologous recombination and repair of DNA. This protein can interact with other RAD51 paralogs and is reported to be important for Holliday junction resolution. Mutations in this gene are associated with Fanconi anemia-like syndrome. This gene is one of four localized to a region of chromosome 17q23 where amplification occurs frequently in breast tumors. Overexpression of the four genes during amplification has been observed and suggests a possible role in tumor progression. Alternative splicing results in multiple transcript variants.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: The RAD51C c.340G>A (p.Gly114Arg) variant involves the alteration of a conserved nucleotide. 4/4 in silico tools predict a damaging outcome for this variant (SNPs&GO not captured due to low reliability index). This variant is absent in 120888 control chromosomes. In addition, one clinical diagnostic laboratory classified this variant as uncertain significance. 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. 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.G114R variant (also known as c.340G>A), located in coding exon 2 of the RAD51C gene, results from a G to A substitution at nucleotide position 340. The glycine at codon 114 is replaced by arginine, an amino acid with dissimilar properties. In multiple assays testing RAD51C function, this alteration showed an abnormal read-out (Hu C et al. Cancer Res, 2023 Aug;83:2557-2571). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The RAD51C c.340G>A variant is predicted to result in the amino acid substitution p.Gly114Arg. To our knowledge, this variant has not been reported in the literature in affected individuals. However, in a functional study of variants of uncertain significance in RAD51C from public databases, p.Gly114Arg showed impaired activity in homology-directed repair (HDR) assays, conferred sensitivity to cisplatin and olaparib, and disrupted formation of protein complexes of RAD51C (Supplementary Tables 1-3 in Hu et al. 2023. PubMed ID: 37253112). This variant has been reported in 0.0080% of alleles in individuals of African descent in gnomAD and has been interpreted as variant of uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/187382/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 114 of the RAD51C protein (p.Gly114Arg). This variant is present in population databases (rs786203690, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with RAD51C-related conditions. ClinVar contains an entry for this variant (Variation ID: 187382). 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 RAD51C protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects RAD51C function (PMID: 37253112). 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. -
