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.

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingColor Diagnostics, LLC DBA Color HealthFeb 16, 2023This missense variant replaces serine with glycine at codon 364 of the RAD51C 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 performed for this variant. This variant has been reported in individuals affected with breast cancer (PMID: 22476429), but also in unaffected individuals (PMID 26261251; https://whi.color.com/variant/17-56811542-A-G.). This variant has been identified in 2/281650 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. -
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 14, 2022The p.S364G variant (also known as c.1090A>G), located in coding exon 9 of the RAD51C gene, results from an A to G substitution at nucleotide position 1090. The serine at codon 364 is replaced by glycine, an amino acid with similar properties. This alteration has been reported in a high-risk breast and/or ovarian cancer family (Lu W et al. Fam. Cancer, 2012 Sep;11:381-5). Another study detected this alteration in 0/3429 patients with invasive epithelial ovarian cancer and 1/2772 unaffected controls (Song H et al. J. Clin. Oncol., 2015 Sep;33:2901-7). 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. -

Uncertain significance, criteria provided, single submitterclinical testingGeneDxJun 10, 2024Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis indicates that this missense variant does not alter protein structure/function; Observed in an individual with a personal history of breast cancer and a family history of breast and/or ovarian cancer (PMID: 22476429); Published functional studies demonstrate normal in vitro homology-directed repair (HDR) activity (PMID: 37253112); This variant is associated with the following publications: (PMID: 34480478, 26261251, 25470109, 26406419, 23117857, 34923718, 14704354, 22476429, 37253112) -
Fanconi anemia complementation group O Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 27, 2024This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 364 of the RAD51C protein (p.Ser364Gly). This variant is present in population databases (rs587782565, gnomAD 0.002%). This missense change has been observed in individual(s) with breast cancer (PMID: 22476429, 26261251). ClinVar contains an entry for this variant (Variation ID: 142585). 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. -
