Invitae RCV000806315 SCV000946305 uncertain significance Congenital disorder of glycosylation, type IIq 2023-07-07 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 651045). This variant has not been reported in the literature in individuals affected with COG2-related conditions. This variant is present in population databases (rs151309110, gnomAD 0.05%). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 258 of the COG2 protein (p.Glu258Lys).
