Labcorp Genetics (formerly Invitae), Labcorp RCV001065696 SCV001230668 uncertain significance Hereditary spastic paraplegia 47 2019-01-28 criteria provided, single submitter clinical testing This sequence change replaces arginine with glycine at codon 113 of the AP4B1 protein (p.Arg113Gly). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and glycine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with AP4B1-related conditions. 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"). 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.
