Labcorp Genetics (formerly Invitae), Labcorp RCV001346511 SCV001540720 uncertain significance Kufor-Rakeb syndrome; Autosomal recessive spastic paraplegia type 78 2020-01-31 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 arginine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with ATP13A2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamine with arginine at codon 770 of the ATP13A2 protein (p.Gln770Arg). The glutamine residue is weakly conserved and there is a small physicochemical difference between glutamine and arginine.
