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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 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=0.25536782).
