Invitae RCV000796625 SCV000936145 uncertain significance Glycogen storage disease IXa1 2018-10-14 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has been observed in an individual affected with glycogen storage disease (PMID: 21646031). This variant is not present in population databases (ExAC no frequency). This sequence change replaces cysteine with tyrosine at codon 326 of the PHKA2 protein (p.Cys326Tyr). The cysteine residue is highly conserved and there is a large physicochemical difference between cysteine and tyrosine.
