GeneDx RCV000760062 SCV000149723 uncertain significance not provided 2018-08-17 criteria provided, single submitter clinical testing This variant is denoted RAD51D c.412A>C at the cDNA level, p.Asn138His (N138H) at the protein level, and results in the change of an Asparagine to a Histidine (AAT>CAT). This variant has been observed in at least one individual with ovarian cancer (Konstanta 2018). RAD51D Asn138His was not observed at a significant allele frequency in large population cohorts (Lek 2016). This variant is located in the RAD51C binding domain (Miller 2004). In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function. Based on currently available evidence, it is unclear whether RAD51D Asn138His is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.

Invitae RCV000649680 SCV000771512 uncertain significance Breast-ovarian cancer, familial 4 2018-12-10 criteria provided, single submitter clinical testing This sequence change replaces asparagine with histidine at codon 138 of the RAD51D protein (p.Asn138His). The asparagine residue is weakly conserved and there is a small physicochemical difference between asparagine and histidine. This variant is present in population databases (rs141690729, ExAC 0.004%). This variant has not been reported in the literature in individuals with RAD51D-related disease. ClinVar contains an entry for this variant (Variation ID: 127888). Algorithms developed to predict the effect of missense changes on protein structure and function 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.
