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]

EEF2 Gene-Disease associations (from GenCC):

• spinocerebellar ataxia type 26

ACMG classification

Our verdict: Benign. The variant received -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.63).
• BP6: Variant 19-3981444-A-G is Benign according to our data. Variant chr19-3981444-A-G is described in ClinVar as Benign. ClinVar VariationId is 585841.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=0.399 with no splicing effect.
• BA1: GnomAdExome4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0509 is higher than 0.05.
