Genes affected

EIF4E3 (HGNC:31837): (eukaryotic translation initiation factor 4E family member 3) EIF4E3 belongs to the EIF4E family of translational initiation factors that interact with the 5-prime cap structure of mRNA and recruit mRNA to the ribosome (Joshi et al., 2004 [PubMed 15153109]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.04745817).

Ambry Genetics

Oct 12, 2021

The c.523G>A (p.V175I) alteration is located in exon 6 (coding exon 6) of the EIF4E3 gene. This alteration results from a G to A substitution at nucleotide position 523, causing the valine (V) at amino acid position 175 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
