Labcorp Genetics (formerly Invitae), Labcorp RCV001052753 SCV001216978 uncertain significance Werner syndrome 2021-02-25 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with WRN-related conditions. This sequence change replaces cysteine with tyrosine at codon 936 of the WRN protein (p.Cys936Tyr). The cysteine residue is highly conserved and there is a large physicochemical difference between cysteine and tyrosine. This variant is not present in population databases (ExAC no frequency). 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 disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
