Labcorp Genetics (formerly Invitae), Labcorp RCV000472604 SCV000541437 uncertain significance Werner syndrome 2016-07-13 criteria provided, single submitter clinical testing This sequence change replaces valine with glutamic acid at codon 641 of the WRN protein (p.Val641Glu). The valine residue is weakly conserved and there is a moderate physicochemical difference between valine and glutamic acid. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a WRN-related disease. 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: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "C25"). In summary, this variant is a novel missense change with uncertain impact on protein function. Therefore, it has been classified as a Variant of Uncertain Significance.
