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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 5 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, 0.92
