Genes affected
EEF2 (HGNC:3214): (eukaryotic translation elongation factor 2) This gene encodes a member of the GTP-binding translation elongation factor family. This protein is an essential factor for protein synthesis. It promotes the GTP-dependent translocation of the nascent protein chain from the A-site to the P-site of the ribosome. This protein is completely inactivated by EF-2 kinase phosporylation. [provided by RefSeq, Jul 2008]

Uncertain significance, criteria provided, single submitterclinical testingInvitaeSep 08, 2023In 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 not expected to disrupt EEF2 protein function. ClinVar contains an entry for this variant (Variation ID: 447308). This variant has not been reported in the literature in individuals affected with EEF2-related conditions. This variant is present in population databases (rs200480185, gnomAD 0.02%). This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 271 of the EEF2 protein (p.Gly271Ser). -

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 31, 2023The c.811G>A (p.G271S) alteration is located in exon 6 (coding exon 6) of the EEF2 gene. This alteration results from a G to A substitution at nucleotide position 811, causing the glycine (G) at amino acid position 271 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
