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.

This variant is denoted RAD51C c.715G>A at the cDNA level, p.Val239Met (V239M) at the protein level, and results in the change of a Valine to a Methionine (GTG>ATG). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. RAD51C Val239Met was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Valine and Methionine share similar properties, this is considered a conservative amino acid substitution. RAD51C Val239Met occurs at a position where amino acids with properties similar to Valine are tolerated across species and is located in the ATPase domain and the Walker B box (Miller 2004, Kim 2011). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available evidence, it is unclear whether RAD51C Val239Met is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. -
