Invitae RCV001297807 SCV001486838 uncertain significance Hyperphosphatasia with intellectual disability syndrome 2 2021-08-28 criteria provided, single submitter clinical testing This sequence change replaces alanine with valine at codon 157 of the PIGO protein (p.Ala157Val). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and valine. This variant is present in population databases (rs764817207, ExAC 0.007%). This variant has not been reported in the literature in individuals affected with PIGO-related conditions. 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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.
