Labcorp Genetics (formerly Invitae), Labcorp RCV000824364 SCV000965260 uncertain significance Hyperphosphatasia with intellectual disability syndrome 2 2018-09-06 criteria provided, single submitter clinical testing This sequence change replaces proline with arginine at codon 303 of the PIGO protein (p.Pro303Arg). The proline residue is weakly conserved and there is a moderate physicochemical difference between proline and arginine. 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 tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with PIGO-related disease. This variant is not present in population databases (ExAC no frequency).
