Labcorp Genetics (formerly Invitae), Labcorp RCV002030551 SCV002268354 uncertain significance Hyperphosphatasia with intellectual disability syndrome 2 2021-04-24 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, 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 conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces phenylalanine with cysteine at codon 146 of the PIGO protein (p.Phe146Cys). The phenylalanine residue is highly conserved and there is a large physicochemical difference between phenylalanine and cysteine.
