Invitae | RCV000471180 | SCV000541408 | uncertain significance | Werner syndrome | 2016-12-14 | criteria provided, single submitter | clinical testing | This sequence change replaces histidine with arginine at codon 671 of the WRN protein (p.His671Arg). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and arginine. 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 (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. In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. |
