Invitae RCV000636363 SCV000757802 likely pathogenic Early infantile epileptic encephalopathy with suppression bursts 2017-11-21 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C55"). This variant has been observed to be de novo in individuals affected with epilepsy (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces lysine with glutamic acid at codon 2338 of the SPTAN1 protein (p.Lys2338Glu). The lysine residue is highly conserved and there is a small physicochemical difference between lysine and glutamic acid.
