Invitae | RCV003517319 | SCV004265308 | uncertain significance | GLUT1 deficiency syndrome 1, autosomal recessive | 2024-01-27 | criteria provided, single submitter | clinical testing | This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 244 of the SLC2A1 protein (p.Met244Thr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SLC2A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 975168). 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 SLC2A1 protein function with a positive predictive value of 95%. 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. |
