Labcorp Genetics (formerly Invitae), Labcorp RCV001979684 SCV002250656 uncertain significance Muscle AMP deaminase deficiency 2021-07-22 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This variant has not been reported in the literature in individuals affected with AMPD1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamine with arginine at codon 453 of the AMPD1 protein (p.Gln453Arg). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and arginine.
