Labcorp Genetics (formerly Invitae), Labcorp RCV002622156 SCV002965214 uncertain significance not provided 2022-08-06 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: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This sequence change replaces aspartic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 520 of the IMPDH1 protein (p.Asp520Ala). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with IMPDH1-related conditions.
