Labcorp Genetics (formerly Invitae), Labcorp RCV002932450 SCV003260286 uncertain significance Muscle AMP deaminase deficiency 2022-07-17 criteria provided, single submitter clinical testing This sequence change replaces methionine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 489 of the AMPD1 protein (p.Met489Leu). This variant is present in population databases (rs182702476, gnomAD 0.2%). This variant has not been reported in the literature in individuals affected with AMPD1-related conditions. 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. 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.
