Labcorp Genetics (formerly Invitae), Labcorp RCV003602388 SCV004445966 uncertain significance Early myoclonic encephalopathy 2023-04-27 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant  is likely to be tolerated. This variant has not been reported in the literature in individuals affected with KCND2-related conditions. Information on the frequency of this variant in the gnomAD database is not available, as this variant may be reported differently in the database. This sequence change replaces serine, which is neutral and polar, with lysine, which is basic and polar, at codon 447 of the KCND2 protein (p.Ser447Lys).
