Invitae RCV001058108 SCV001222652 uncertain significance Walker-Warburg congenital muscular dystrophy 2019-12-31 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid with lysine at codon 334 of the FKRP protein (p.Glu334Lys). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and lysine. 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with FKRP-related conditions. This variant is not present in population databases (ExAC no frequency).
