Labcorp Genetics (formerly Invitae), Labcorp RCV002591692 SCV003495544 uncertain significance Glycogen storage disease IXc 2022-02-23 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 42 of the PHKG2 protein (p.Val42Ile). This variant is present in population databases (rs777606340, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with PHKG2-related conditions. 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 not expected to disrupt PHKG2 protein function. 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.
