Labcorp Genetics (formerly Invitae), Labcorp RCV000210212 SCV001562004 uncertain significance Lipoic acid synthetase deficiency 2023-12-11 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 215 of the LIAS protein (p.Asp215Glu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with nonketotic hyperglycinemia (PMID: 24334290). ClinVar contains an entry for this variant (Variation ID: 224602). 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 expected to disrupt LIAS protein function with a positive predictive value of 80%. 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.
