Labcorp Genetics (formerly Invitae), Labcorp RCV001347983 SCV001542267 uncertain significance GM3 synthase deficiency 2021-08-26 criteria provided, single submitter clinical testing This sequence change replaces arginine with glycine at codon 369 of the ST3GAL5 protein (p.Arg369Gly). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and glycine. This variant is present in population databases (rs745878094, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with ST3GAL5-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.
