Labcorp Genetics (formerly Invitae), Labcorp RCV001203799 SCV001374976 uncertain significance Familial acute necrotizing encephalopathy 2019-09-01 criteria provided, single submitter clinical testing This sequence change replaces glutamine with arginine at codon 1689 of the RANBP2 protein (p.Gln1689Arg). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and arginine. 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with RANBP2-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 ExAC database.
