Labcorp Genetics (formerly Invitae), Labcorp RCV001936302 SCV002204132 uncertain significance Glycogen storage disease XV; Polyglucosan body myopathy type 2 2022-03-18 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 21 of the GYG1 protein (p.Val21Ile). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with GYG1-related conditions. 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. 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.
