Invitae RCV000792883 SCV000932209 pathogenic Non-ketotic hyperglycinemia 2018-12-10 criteria provided, single submitter clinical testing This sequence change replaces valine with glycine at codon 905 of the GLDC protein (p.Val905Gly). The valine residue is weakly conserved and there is a moderate physicochemical difference between valine and glycine. This variant is present in population databases (rs188269735, ExAC 0.04%). This variant has been observed in combination with other GLDC variants in individuals affected with non-ketotic hypoglycemia; in at least one case, it was found on the opposite chromosome (in trans) from a pathogenic variant (PMID: 16450403, 26179960, 28244183). This finding is consistent with autosomal recessive inheritance, and suggests that this variant contributes to disease. Experimental studies have shown that this missense change results in a protein with very low activity (PMID: 28244183). For these reasons, this variant has been classified as Pathogenic.
