Color Diagnostics, LLC DBA Color Health RCV000580900 SCV000686314 uncertain significance Hereditary cancer-predisposing syndrome 2023-12-05 criteria provided, single submitter clinical testing This missense variant replaces phenylalanine with serine at codon 346 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.
Ambry Genetics RCV000580900 SCV001178127 uncertain significance Hereditary cancer-predisposing syndrome 2024-08-09 criteria provided, single submitter clinical testing The p.F346S variant (also known as c.1037T>C), located in coding exon 9 of the RAD51C gene, results from a T to C substitution at nucleotide position 1037. The phenylalanine at codon 346 is replaced by serine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Labcorp Genetics (formerly Invitae), Labcorp RCV001314338 SCV001504867 uncertain significance Fanconi anemia complementation group O 2020-05-29 criteria provided, single submitter clinical testing This sequence change replaces phenylalanine with serine at codon 346 of the RAD51C protein (p.Phe346Ser). The phenylalanine residue is moderately conserved and there is a large physicochemical difference between phenylalanine and serine. 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with RAD51C-related conditions. ClinVar contains an entry for this variant (Variation ID: 490118). This variant is not present in population databases (ExAC no frequency).
