Labcorp Genetics (formerly Invitae), Labcorp RCV002616241 SCV003507215 uncertain significance Holocarboxylase synthetase deficiency 2022-10-27 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 279 of the HLCS protein (p.Glu279Lys). 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. 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 HLCS protein function. This variant has not been reported in the literature in individuals affected with HLCS-related conditions. This variant is present in population databases (rs751093392, gnomAD 0.003%).
