Labcorp Genetics (formerly Invitae), Labcorp RCV001238959 SCV001411799 uncertain significance 3-hydroxy-3-methylglutaryl-CoA synthase deficiency 2021-08-27 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with glutamic acid at codon 365 of the HMGCS2 protein (p.Asp365Glu). The aspartic acid residue is weakly conserved and there is a small physicochemical difference between aspartic acid and glutamic acid. This variant is present in population databases (rs587690380, ExAC 0.2%). This variant has not been reported in the literature in individuals affected with HMGCS2-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.
