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: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This 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 . To our knowledge, functional studies have not been performed for this variant. This variant has been reported in an individual affected with breast cancer (PMID: 22476429) and also detected in a female unaffected with cancer at age 70 and older (https://whi.color.com/variant/17-56811542-A-G). This variant has been reported in a breast cancer case-control meta-analysis in 1/60466 cases and 1/53461 unaffected individuals (PMID: 33471991; Leiden Open Variation Database DB-ID RAD51C_000228), and in an ovarian cancer case-control study in 1/2772 unaffected individuals and absent in 3429 cases (PMID: 26261251). 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. -

Not 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) -

This 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. Experimental studies have shown that this missense change does not substantially affect 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. -
