Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2 PP2 PP3

The NM_001961.4(EEF2):​c.637G>A​(p.Gly213Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: not found (cov: 33)
• Consequence: EEF2 NM_001961.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 7.86

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]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), EEF2. . Gene score misZ 4.8778 (greater than the threshold 3.09). Trascript score misZ 3.5943 (greater than threshold 3.09). GenCC has associacion of gene with spinocerebellar ataxia type 26.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.807
