Invitae RCV000529212 SCV000654349 uncertain significance Epileptic encephalopathy, childhood-onset 2017-04-04 criteria provided, single submitter clinical testing This sequence change replaces proline with alanine at codon 1776 of the CHD2 protein (p.Pro1776Ala). The proline residue is weakly conserved and there is a small physicochemical difference between proline and alanine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a CHD2-related disease. 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: "Not Scored"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance.
