Invitae RCV000816481 SCV000956992 uncertain significance Werner syndrome 2018-12-27 criteria provided, single submitter clinical testing 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 output the following: SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0". The glutamine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with WRN-related conditions. This variant is present in population databases (rs775535952, ExAC 0.006%). This sequence change replaces arginine with glutamine at codon 1305 of the WRN protein (p.Arg1305Gln). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and glutamine.
