Labcorp Genetics (formerly Invitae), Labcorp RCV000531314 SCV000655311 uncertain significance Polyglucosan body myopathy type 1 2017-07-22 criteria provided, single submitter clinical testing This variant is not present in population databases (ExAC no frequency). 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 do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with RBCK1-related disease. This sequence change replaces glutamic acid with lysine at codon 146 of the RBCK1 protein (p.Glu146Lys). The glutamic acid residue is moderately conserved and there is a small physicochemical difference between glutamic acid and lysine.
