Labcorp Genetics (formerly Invitae), Labcorp RCV001981725 SCV002221459 uncertain significance Werner syndrome 2023-09-21 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 399 of the WRN protein (p.Glu399Gln). This variant has not been reported in the literature in individuals affected with WRN-related conditions. 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 1444213).
