Invitae RCV001931118 SCV002190707 uncertain significance Autosomal recessive early-onset Parkinson disease 7 2020-11-15 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but 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 PARK7-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces lysine with arginine at codon 132 of the PARK7 protein (p.Lys132Arg). The lysine residue is highly conserved and there is a small physicochemical difference between lysine and arginine.
