Labcorp Genetics (formerly Invitae), Labcorp RCV003878205 SCV004677396 uncertain significance Werner syndrome 2023-04-27 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change replaces leucine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 268 of the WRN protein (p.Leu268Ile). 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 tolerated.
