Labcorp Genetics (formerly Invitae), Labcorp RCV001884249 SCV002155056 uncertain significance Hereditary spastic paraplegia 63; Pontocerebellar hypoplasia type 9 2021-09-15 criteria provided, single submitter clinical testing 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. This variant has not been reported in the literature in individuals affected with AMPD2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with histidine at codon 42 of the AMPD2 protein (p.Arg42His). The arginine residue is weakly conserved and there is a small physicochemical difference between arginine and histidine. 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.
