Genes affected

EIF4EBP2 (HGNC:3289): (eukaryotic translation initiation factor 4E binding protein 2) This gene encodes a member of the eukaryotic translation initiation factor 4E binding protein family. The gene products of this family bind eIF4E and inhibit translation initiation. However, insulin and other growth factors can release this inhibition via a phosphorylation-dependent disruption of their binding to eIF4E. Regulation of protein production through these gene products have been implicated in cell proliferation, cell differentiation and viral infection. [provided by RefSeq, Oct 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.949

Collection Method: clinical testing

The c.161A>T (p.Y54F) alteration is located in exon 2 (coding exon 2) of the EIF4EBP2 gene. This alteration results from a A to T substitution at nucleotide position 161, causing the tyrosine (Y) at amino acid position 54 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
