Labcorp Genetics (formerly Invitae), Labcorp RCV002917693 SCV003251460 uncertain significance Spinocerebellar ataxia type 19/22 2021-12-17 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with KCND3-related conditions. 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C55"). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces tryptophan, which is neutral and slightly polar, with leucine, which is neutral and non-polar, at codon 170 of the KCND3 protein (p.Trp170Leu).
