Invitae RCV000129944 SCV000628244 uncertain significance Hereditary cancer-predisposing syndrome 2018-09-03 criteria provided, single submitter clinical testing This sequence change replaces lysine with glutamine at codon 1026 of the RAD50 protein (p.Lys1026Gln). The lysine residue is moderately conserved and there is a small physicochemical difference between lysine and glutamine. The frequency data for this variant (rs587781740) in the population databases is unreliable, as metrics indicate poor quality at this position in the ExAC database. This variant has not been reported in the literature in individuals with a RAD50-related disease. ClinVar contains an entry for this variant (Variation ID: 141431). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies. In summary, this variant is a rare missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance.
