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.

The p.R319* pathogenic mutation (also known as c.955C>T), located in coding exon 7 of the RAD51C gene, results from a C to T substitution at nucleotide position 955. This changes the amino acid from an arginine to a stop codon within coding exon 7. This mutation has been reported in multiple individuals with personal and/or family histories of breast and/or ovarian cancer (Loveday C et al. Nat. Genet., 2012 Apr;44:475-6; author reply 476; Couch FJ et al. J Clin Oncol, 2015 Feb;33:304-11; Song H et al. J Clin Oncol, 2015 Sep;33:2901-7; Norquist BM et al. JAMA Oncol, 2016 Apr;2:482-90; Kraus C et al. Int J Cancer, 2017 Jan;140:95-102; Schoolmeester JK et al. Hum. Pathol., 2017 12;70:14-26; Hoyer J et al. BMC Cancer, 2018 Sep;18:926; Dorling et al. N Engl J Med. 2021 02;384:428-439). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.

Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant changes 1 nucleotide in exon 7 of the RAD51C gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with breast or ovarian cancer (PMID: 22538716, 25452441, 26261251, 26720728, 27616075, 28709830, 32359370). This variant has been identified in 2/251282 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of RAD51C function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic.

This sequence change creates a premature translational stop signal (p.Arg319*) in the RAD51C gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RAD51C are known to be pathogenic (PMID: 20400964, 21990120, 24800917, 29278735). This variant is present in population databases (rs587781287, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with breast and ovarian cancer (PMID: 22538716, 25452441, 26261251). ClinVar contains an entry for this variant (Variation ID: 140799). For these reasons, this variant has been classified as Pathogenic.
