Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM1PP3PP5_Very_Strong

The NM_014239.4(EIF2B2):​c.599G>T​(p.Gly200Val) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000488 in 1,612,046 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 15/24 in silico tools predict a damaging outcome for this variant. 2/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G200S) has been classified as Uncertain significance.

Genes affected
EIF2B2 (HGNC:3258): (eukaryotic translation initiation factor 2B subunit beta) This gene encodes the beta subunit of eukaryotic initiation factor-2B (EIF2B). EIF2B is involved in protein synthesis and exchanges GDP and GTP for its activation and deactivation. [provided by RefSeq, Aug 2011]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 11 ACMG points.

PM1
In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 1 uncertain in NM_014239.4
PP3
Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF. No scorers claiming Uncertain. Scorers claiming Benign: max_spliceai.
PP5
Variant 14-75005867-G-T is Pathogenic according to our data. Variant chr14-75005867-G-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 208575.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
