Labcorp Genetics (formerly Invitae), Labcorp RCV001917275 SCV002154988 uncertain significance Propionic acidemia 2021-07-10 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 PCCB-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces aspartic acid with histidine at codon 303 of the PCCB protein (p.Asp303His). The aspartic acid residue is highly conserved and there is a moderate physicochemical difference between aspartic acid and histidine.
