Labcorp Genetics (formerly Invitae), Labcorp RCV001041847 SCV001205492 uncertain significance Holocarboxylase synthetase deficiency 2022-07-09 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 679 of the HLCS protein (p.Ala679Thr). This variant is present in population databases (rs376898721, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with HLCS-related conditions. ClinVar contains an entry for this variant (Variation ID: 839968). 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. 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.
