GeneDx RCV000482836 SCV000571571 uncertain significance not provided 2018-02-05 criteria provided, single submitter clinical testing This variant is denoted RAD51C c.52C>T at the cDNA level, p.Pro18Ser (P18S) at the protein level, and results in the change of a Proline to a Serine (CCG>TCG). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. RAD51C Pro18Ser was not observed at a significant allele frequency in large population cohorts (Lek 2016). RAD51C Pro18Ser is located in the region required for holiday junction resolution activity (UniProt). In-silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect. Based on currently available evidence, it is unclear whether RAD51C Pro18Ser is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.

Invitae RCV000810573 SCV000950786 uncertain significance Fanconi anemia, complementation group O 2019-11-26 criteria provided, single submitter clinical testing This sequence change replaces proline with serine at codon 18 of the RAD51C protein (p.Pro18Ser). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and serine. This variant is present in population databases (rs547142453, ExAC 0.04%). This variant has been observed in individuals affected with a personal and/or family history of breast and/or ovarian cancer (PMID: 29470806). ClinVar contains an entry for this variant (Variation ID: 232581). 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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.
