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.

Submissions by phenotype

Hereditary cancer-predisposing syndrome Pathogenic:3
Pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsSep 08, 2023The p.W305* pathogenic mutation (also known as c.914G>A), located in coding exon 7 of the RAD51C gene, results from a G to A substitution at nucleotide position 914. This changes the amino acid from a tryptophan to a stop codon within coding exon 7. 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. -
Pathogenic, criteria provided, single submittercurationSema4, Sema4Jul 27, 2021- -
Pathogenic, criteria provided, single submitterclinical testingColor Diagnostics, LLC DBA Color HealthNov 16, 2020This 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. This variant has been reported in an individual affected with ovarian cancer (PMID: 30322717). This variant has been identified in 1/31390 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. -

Pathogenic, criteria provided, single submitterclinical testingMyriad Genetics, Inc.Apr 05, 2023This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. -
not provided Pathogenic:2
Pathogenic, criteria provided, single submitterclinical testingGeneDxSep 28, 2017This variant is denoted RAD51C c.914G>A at the cDNA level and p.Trp305Ter (W305X) at the protein level. The substitution creates a nonsense variant, which changes a Tryptophan to a premature stop codon (TGG>TAG), and is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. Although this variant has not, to our knowledge, been reported in the literature, it is considered pathogenic. -
Pathogenic, criteria provided, single submitterclinical testingQuest Diagnostics Nichols Institute San Juan CapistranoJun 04, 2019The variant creates a premature nonsense codon, and is therefore predicted to result in the loss of a functional protein. Found in at least one symptomatic patient, and found in general population data that is consistent with pathogenicity. -

Pathogenic, criteria provided, single submitterclinical testingInvitaeSep 18, 2023This variant has not been reported in the literature in individuals affected with RAD51C-related conditions. For these reasons, this variant has been classified as Pathogenic. RNA analysis performed to evaluate the impact of this premature translational stop signal on mRNA splicing indicates it does not significantly alter splicing (Invitae). ClinVar contains an entry for this variant (Variation ID: 232614). This variant is present in population databases (no rsID available, gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Trp305*) 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). -

RAD51C-related disorder Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesFeb 01, 2023The RAD51C c.914G>A variant is predicted to result in premature protein termination (p.Trp305*). This variant was reported in individuals with ovarian cancer (Supplemental Table 1, Carter et al 2018. PubMed ID: 30322717) and breast cancer (Supplementary Table 3, Palmer et al 2020. PubMed ID: 32427313; Table 1, Bagherzadeh et al 2020. PubMed ID: 32809180). This variant is reported in 0.011% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/17-56801410-G-A). This variant is interpreted as pathogenic by several laboratories in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/232614/). Nonsense variants in RAD51C are expected to be pathogenic (Meindl et al 2010. PubMed ID: 20400964). Taken together, this variant is interpreted as pathogenic. -
