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]

The c.575C>T (p.T192I) alteration is located in exon 6 (coding exon 6) of the EIF4E2 gene. This alteration results from a C to T substitution at nucleotide position 575, causing the threonine (T) at amino acid position 192 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
