• chr3-184143455-A-T
• rs843358
• NM_003907.3:c.1759A>T

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_003907.3(EIF2B5):​c.1759A>T​(p.Ile587Leu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I587V) has been classified as Benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: EIF2B5 NM_003907.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 5.21
• Publications: 54 publications found

Genes affected

EIF2B5 (HGNC:3261): (eukaryotic translation initiation factor 2B subunit epsilon) This gene encodes one of five subunits of eukaryotic translation initiation factor 2B (EIF2B), a GTP exchange factor for eukaryotic initiation factor 2 and an essential regulator for protein synthesis. Mutations in this gene and the genes encoding other EIF2B subunits have been associated with leukoencephalopathy with vanishing white matter. [provided by RefSeq, Nov 2009]

EIF2B5-DT (HGNC:55202): (EIF2B5 divergent transcript)

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
