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 Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The p.R168* pathogenic mutation (also known as c.502A>T), located in coding exon 3 of the RAD51C gene, results from an A to T substitution at nucleotide position 502. This changes the amino acid from an arginine to a stop codon within coding exon 3. This alteration has been reported in multiple individuals diagnosed with breast cancer (Lhota F et al. Clin. Genet. 2016 10;90:324-33; Yablonski-Peretz T et al. Breast Cancer Res. Treat. 2016 Jan;155:133-8; Susswein LR et al. Genet. Med. 2016 08;18:823-32). 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. -

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMay 02, 2023ClinVar contains an entry for this variant (Variation ID: 141095). This premature translational stop signal has been observed in individual(s) with breast cancer (PMID: 26687385, 26822949). This variant is present in population databases (rs587781490, gnomAD 0.0009%). This sequence change creates a premature translational stop signal (p.Arg168*) 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). For these reasons, this variant has been classified as Pathogenic. -
