RCV001347150 | SCV001541398 | uncertain significance | Early myoclonic encephalopathy | 2021-02-25 | criteria provided, single submitter | clinical testing | 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. This variant has not been reported in the literature in individuals with KCND2-related conditions. This sequence change replaces alanine with aspartic acid at codon 120 of the KCND2 protein (p.Ala120Asp). The alanine residue is moderately conserved and there is a moderate physicochemical difference between alanine and aspartic acid. This variant is not present in population databases (ExAC no frequency). |
