Invitae RCV000804131 SCV000944026 uncertain significance not provided 2021-09-01 criteria provided, single submitter clinical testing This sequence change replaces lysine with arginine at codon 862 of the SZT2 protein (p.Lys862Arg). The lysine residue is moderately conserved and there is a small physicochemical difference between lysine and arginine. This variant is present in population databases (rs530645704, ExAC 0.05%). This variant has not been reported in the literature in individuals affected with SZT2-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
