Labcorp Genetics (formerly Invitae), Labcorp RCV001931083 SCV002187609 uncertain significance Long QT syndrome 2021-10-13 criteria provided, single submitter clinical testing 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. 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 lysine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with AKAP9-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with lysine at codon 2658 of the AKAP9 protein (p.Arg2658Lys). The arginine residue is weakly conserved and there is a small physicochemical difference between arginine and lysine.
