Labcorp Genetics (formerly Invitae), Labcorp RCV001348056 SCV001542344 uncertain significance Hereditary spastic paraplegia 7 2018-05-24 criteria provided, single submitter clinical testing This sequence change replaces lysine with glutamic acid at codon 177 of the SPG7 protein (p.Lys177Glu). The lysine residue is moderately conserved and there is a small physicochemical difference between lysine and glutamic acid. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with SPG7-related disease. 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: "Tolerated"; 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.
