GeneDx RCV000482019 SCV000570354 uncertain significance not provided 2021-01-18 criteria provided, single submitter clinical testing Not observed in large population cohorts (Lek 2016); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Ambry Genetics RCV000564108 SCV000663761 uncertain significance Hereditary cancer-predisposing syndrome 2023-01-31 criteria provided, single submitter clinical testing The p.H179R variant (also known as c.536A>G), located in coding exon 3 of the RAD51C gene, results from an A to G substitution at nucleotide position 536. The histidine at codon 179 is replaced by arginine, an amino acid with highly similar properties. This amino acid position is highly 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.
Color Diagnostics, LLC DBA Color Health RCV000564108 SCV000691244 uncertain significance Hereditary cancer-predisposing syndrome 2023-12-04 criteria provided, single submitter clinical testing This missense variant replaces histidine with arginine at codon 179 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 RAD51C-related disorders in the literature. This variant has not been identified 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.
Invitae RCV001062468 SCV001227270 uncertain significance Fanconi anemia complementation group O 2024-01-27 criteria provided, single submitter clinical testing This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 179 of the RAD51C protein (p.His179Arg). 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: 421223). 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 disruptive. 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.
