Labcorp Genetics (formerly Invitae), Labcorp RCV003084764 SCV003483387 uncertain significance Hyperinsulinism-hyperammonemia syndrome 2022-09-16 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available"). This variant has not been reported in the literature in individuals affected with GLUD1-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 60 of the GLUD1 protein (p.Arg60Ser).
