Labcorp Genetics (formerly Invitae), Labcorp RCV001976318 SCV002264966 uncertain significance Glycogen storage disease, type VI 2020-11-16 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt PYGL protein function. This variant has not been reported in the literature in individuals with PYGL-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with arginine at codon 289 of the PYGL protein (p.Gly289Arg). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and arginine.
