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

This missense variant replaces glycine with arginine at codon 3 of the RAD51C protein. Computational prediction tool suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). Functional studies have shown that this variant could restore normal mitomycin C sensitivity and RAD51 foci formation in the RAD51C mutant cells (PMID: 20400964). This variant has been reported in individuals affected with breast and/or ovarian cancer (PMID: 20400964, 25470109, 26261251, 26976419). This variant has been identified in 11/282672 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. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely 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. -

In silico analysis supports that this missense variant does not alter protein structure/function; Published functional studies demonstrate no damaging effect: cell survival and RAD51 foci formation similar to wild-type (Meindl et al., 2010); Observed in individuals with breast, ovarian, and other cancers (Scheckenbach et al., 2014; Song et al., 2015; Tung et al., 2016); This variant is associated with the following publications: (PMID: 24315737, 26261251, 23117857, 26976419, 25470109, 21537932, 28829762, 33471991, 20400964) -

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 3 of the RAD51C protein (p.Gly3Arg). This variant is present in population databases (rs376403182, gnomAD 0.007%). This missense change has been observed in individual(s) with breast cancer, ovarian cancer and head and neck squamous cell carcinoma (PMID: 20400964, 24315737, 25470109, 26261251, 26976419). ClinVar contains an entry for this variant (Variation ID: 184411). 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: 20400964). RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (Invitae). 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. -
