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.

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Oct 06, 2016	Variant summary: The RAD51C c.601C>G (p.Leu201Val) variant causes a missense change involving a non-conserved nucleotide with 3/4 in silico tools (SNPs&GO not captured here due to low reliability index) predict a benign outcome, although these predictions have yet to be functionally assessed. The variant of interest was observed in the large, broad control population, ExAC, with an allele frequency of 2/121042 (1/60521), which does not exceed the estimated maximal expected allele frequency for a pathogenic RAD51C variant of 1/16000. A publication cites the variant in an affected individual with a classification of "unknown significance." Reputable databases and clinical diagnositic laboratories have not, to our knowledge, cited the variant of interest. Therefore, until additional clinical and/or functional studies become available, the variant of interest has been classified as a "Variant of Uncertain Significance (VUS)." -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Apr 07, 2022	Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Observed in individuals with a personal history of breast cancer and other cancers in published literature (Tung 2016, Mandelker 2017); This variant is associated with the following publications: (PMID: 26976419, 28873162, 14704354) -

Fanconi anemia complementation group O

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 27, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 29, 2023	This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 201 of the RAD51C protein (p.Leu201Val). This variant is present in population databases (rs531838785, gnomAD 0.03%). This missense change has been observed in individual(s) with breast cancer and unspecified cancer (PMID: 26976419, 28873162). ClinVar contains an entry for this variant (Variation ID: 496506). 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 with a negative predictive value of 80%. 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. -

Hereditary cancer-predisposing syndrome

Uncertain:1Benign:1

Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Jan 29, 2024	This 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Dec 06, 2023	This missense variant replaces leucine with valine at codon 201 of the RAD51C protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has been observed in an individual affected with breast cancer (PMID: 26976419) and with unspecified advanced cancer (PMID: 28873162). This variant has been identified in 3/251262 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. -
