Genetic Variant EIF4E2:p.Arg241Trp (chr2-232569000-C-T) – ACMG Classification: Likely_benign (-5 pts)

Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP4BS2

The NM_004846.4(EIF4E2):c.721C>T(p.Arg241Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000204 in 1,614,168 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R241Q) has been classified as Uncertain significance.

Genes affected

EIF4E2 (HGNC:3293): (eukaryotic translation initiation factor 4E family member 2) Enables ubiquitin protein ligase binding activity. Involved in positive regulation of miRNA mediated inhibition of translation. Acts upstream of or within negative regulation of translation. Located in P-body. Part of mRNA cap binding activity complex. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.721C>T (p.R241W) alteration is located in exon 7 (coding exon 7) of the EIF4E2 gene. This alteration results from a C to T substitution at nucleotide position 721, causing the arginine (R) at amino acid position 241 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
