Ambry Genetics RCV000222700 SCV000273131 uncertain significance Hereditary cancer-predisposing syndrome 2023-04-06 criteria provided, single submitter clinical testing The p.E89K variant (also known as c.265G>A), located in coding exon 2 of the RAD51C gene, results from a G to A substitution at nucleotide position 265. The glutamic acid at codon 89 is replaced by lysine, 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.
Invitae RCV000648260 SCV000770074 uncertain significance Fanconi anemia complementation group O 2023-10-07 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 89 of the RAD51C protein (p.Glu89Lys). This variant is present in population databases (no rsID available, gnomAD 0.003%). 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: 229792). 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.
Color Diagnostics, LLC DBA Color Health RCV000222700 SCV001355174 uncertain significance Hereditary cancer-predisposing syndrome 2021-08-09 criteria provided, single submitter clinical testing This missense variant replaces glutamic acid with lysine at codon 89 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 hereditary cancer in the literature. This variant has been identified in 1/251462 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.
Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV001194264 SCV001363656 uncertain significance not specified 2019-06-06 criteria provided, single submitter clinical testing Variant summary: RAD51C c.265G>A (p.Glu89Lys) results in a conservative amino acid change located in the DNA recombination and repair protein Rad51-like, C-terminal domain of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 251462 control chromosomes (gnomAD). 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.265G>A in individuals affected with Hereditary Breast and Ovarian Cancer and no experimental evidence demonstrating its impact on protein function have been reported. Two ClinVar submissions from clinical diagnostic laboratories (evaluation after 2014) cite the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance.

Quest Diagnostics Nichols Institute San Juan Capistrano RCV001753653 SCV004220138 uncertain significance not provided 2022-12-13 criteria provided, single submitter clinical testing The variant has not been reported in the published literature. The frequency of this variant in the general population, 0.000004 (1/251462 chromosomes, http://gnomad.broadinstitute.org), is uninformative in 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 conflicting predictions that this variant is benign or damaging. Based on the available information, we are unable to determine the clinical significance of this variant.
