Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 3P and 1B. PM2 PP2 BP4

The NM_001415.4(EIF2S3):​c.324T>A​(p.Ser108Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).

Genes affected

EIF2S3 (HGNC:3267): (eukaryotic translation initiation factor 2 subunit gamma) The protein encoded by this gene is the largest subunit of a heterotrimeric GTP-binding protein involved in the recruitment of methionyl-tRNA(i) to the 40 S ribosomal subunit. [provided by RefSeq, Jan 2010]

EIF2S3 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 2 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), EIF2S3. . Gene score misZ 3.6078 (greater than the threshold 3.09). GenCC has associacion of gene with MEHMO syndrome, diabetes mellitus.
• BP4: Computational evidence support a benign effect (MetaRNN=0.38057172).
