RCV001945914 | SCV002203033 | uncertain significance | Spinocerebellar ataxia type 19/22 | 2021-06-01 | 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 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 has not been reported in the literature in individuals with KCND3-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with alanine at codon 184 of the KCND3 protein (p.Val184Ala). The valine residue is highly conserved and there is a small physicochemical difference between valine and alanine. |
