Labcorp Genetics (formerly Invitae), Labcorp RCV000698634 SCV000827313 uncertain significance Fanconi anemia complementation group O 2023-10-22 criteria provided, single submitter clinical testing This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 320 of the RAD51C protein (p.Lys320Glu). This variant is not present in population databases (gnomAD no frequency). 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: 576199). 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.
Ambry Genetics RCV001019511 SCV001180879 uncertain significance Hereditary cancer-predisposing syndrome 2021-04-20 criteria provided, single submitter clinical testing The p.K320E variant (also known as c.958A>G), located in coding exon 7 of the RAD51C gene, results from an A to G substitution at nucleotide position 958. The lysine at codon 320 is replaced by glutamic acid, an amino acid with similar properties. This amino acid position is 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.
Quest Diagnostics Nichols Institute San Juan Capistrano RCV003478429 SCV004220156 uncertain significance not provided 2022-12-03 criteria provided, single submitter clinical testing It has not been reported in large, multi-ethnic general populations (http://gnomad.broadinstitute.org). In the published literature, the variant has been reported in an individual with breast cancer in a large breast cancer association study (PMID: 33471991 (2021), see also LOVD (https://databases.lovd.nl/shared/variants/RAD51C). 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.
