Invitae RCV000824302 SCV000965195 likely pathogenic Non-ketotic hyperglycinemia 2018-11-01 criteria provided, single submitter clinical testing This sequence change replaces lysine with glutamic acid at codon 819 of the GLDC protein (p.Lys819Glu). The lysine residue is highly conserved and there is a small physicochemical difference between lysine and glutamic acid. This variant is not present in population databases (ExAC no frequency). This variant has been observed on the opposite chromosome (in trans) from a pathogenic variant in individuals affected with glycine encephalopathy (PMID: 27362913, Invitae). This finding is consistent with autosomal recessive inheritance, and suggests that this variant contributes to 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: "Probably Damaging"; Align-GVGD: "Class C0"). 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.
