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.

not provided Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingGeneDxJan 23, 2020Not observed at a significant frequency in large population cohorts (Lek 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Uncertain significance, criteria provided, single submitterclinical testingQuest Diagnostics Nichols Institute San Juan CapistranoMay 05, 2021- -
Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
Uncertain significance, criteria provided, single submitterclinical testingColor Diagnostics, LLC DBA Color HealthJan 09, 2023This missense variant replaces valine with methionine at codon 41 of the RAD51C protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with RAD51C-related disorders in the literature. This variant has been identified in 2/251432 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. -
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2024This 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. -
not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpMar 12, 2021Variant summary: RAD51C c.121G>A (p.Val41Met) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 251432 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.121G>A in individuals affected with Hereditary Breast And Ovarian Cancer Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -
Fanconi anemia complementation group O Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 17, 2023This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 41 of the RAD51C protein (p.Val41Met). This variant is present in population databases (no rsID available, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with RAD51C-related conditions. ClinVar contains an entry for this variant (Variation ID: 492361). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RAD51C protein function. 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. -
Breast-ovarian cancer, familial, susceptibility to, 3 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingKCCC/NGS Laboratory, Kuwait Cancer Control CenterJul 07, 2023The p.Val41Met variant located in coding exon 1 of the RAD51C gene, results from a G to A substitution at nucleotide position 121. The valine at codon 41 is replaced by methionine, This amino acid position is not conserved (PhyloP=0). This variant not present in our local database nor was it identified in the Genome Aggregation Database The computational analyses (PolyPhen-2, SIFT, MutationTaster) do not suggest a high pathogenic impacts on the protein; however, this information is not predictive enough to rule out pathogenicity. ClinVar has an entry (492361) for this variant reported as uncertain significance from six diffrent diagnostic labs .. Since supporting evidence is limited at this time, this variant is classified as of uncertain significance. -
