Labcorp Genetics (formerly Invitae), Labcorp RCV001940279 SCV002189182 uncertain significance Spinocerebellar ataxia type 19/22 2022-07-25 criteria provided, single submitter clinical testing This sequence change replaces methionine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 339 of the KCND3 protein (p.Met339Ile). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with KCND3-related conditions. ClinVar contains an entry for this variant (Variation ID: 1417852). 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 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.
