Labcorp Genetics (formerly Invitae), Labcorp RCV001309897 SCV001499411 uncertain significance GM3 synthase deficiency 2022-05-25 criteria provided, single submitter clinical testing This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 15 of the ST3GAL5 protein (p.Gln15Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ST3GAL5-related conditions. ClinVar contains an entry for this variant (Variation ID: 1012008). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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.
