Ambry Genetics RCV000167220 SCV000218057 uncertain significance Hereditary cancer-predisposing syndrome 2022-12-17 criteria provided, single submitter clinical testing The p.T352N variant (also known as c.1055C>A), located in coding exon 9 of the RAD51C gene, results from a C to A substitution at nucleotide position 1055. The threonine at codon 352 is replaced by asparagine, an amino acid with some similar properties. This amino acid position is poorly 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.
Invitae RCV000198946 SCV000255183 uncertain significance Fanconi anemia complementation group O 2024-01-31 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 352 of the RAD51C protein (p.Thr352Asn). This variant is present in population databases (rs786203771, gnomAD 0.009%). 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: 187487). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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.

Quest Diagnostics Nichols Institute San Juan Capistrano RCV003477637 SCV004220131 uncertain significance not provided 2023-05-31 criteria provided, single submitter clinical testing This variant has not been reported in the published literature. The frequency of this variant in the general population, 0.000087 (3/34528 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant.
