Baylor Genetics RCV001331040 SCV001522949 uncertain significance Non-ketotic hyperglycinemia 2020-01-31 criteria provided, single submitter clinical testing This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868].
Labcorp Genetics (formerly Invitae), Labcorp RCV001331040 SCV003300324 pathogenic Non-ketotic hyperglycinemia 2023-10-22 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 360 of the GLDC protein (p.Val360Leu). This variant is present in population databases (rs373482451, gnomAD 0.003%). This missense change has been observed in individual(s) with non-ketotic hyperglycinemia (PMID: 26179960, 27362913). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 1029690). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt GLDC protein function. For these reasons, this variant has been classified as Pathogenic.
