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 significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 05, 2023	The p.T96S variant (also known as c.287C>G), located in coding exon 2 of the RAD51C gene, results from a C to G substitution at nucleotide position 287. The threonine at codon 96 is replaced by serine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This variant has not been reported in the literature in individuals affected with RAD51C-related conditions. 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. 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. ClinVar contains an entry for this variant (Variation ID: 409848). This variant is present in population databases (rs750381200, gnomAD 0.002%). This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 96 of the RAD51C protein (p.Thr96Ser). -
