Invitae RCV000798037 SCV000937631 uncertain significance Epileptic encephalopathy, childhood-onset 2018-10-04 criteria provided, single submitter clinical testing This sequence change replaces lysine with glutamic acid at codon 1439 of the CHD2 protein (p.Lys1439Glu). The lysine residue is moderately conserved and there is a small physicochemical difference between lysine and glutamic acid. This variant is present in population databases (rs368570245, ExAC 0.003%). This variant has not been reported in the literature in individuals with CHD2-related disease. 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.
