Labcorp Genetics (formerly Invitae), Labcorp RCV001301585 SCV001490760 uncertain significance Juvenile onset Parkinson disease 19A 2020-09-24 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 alanine 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 DNAJC6-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change replaces glycine with alanine at codon 34 of the DNAJC6 protein (p.Gly34Ala). The glycine residue is weakly conserved and there is a small physicochemical difference between glycine and alanine.
