The c.691A>G (p.R231G) alteration is located in exon 7 (coding exon 7) of the EIF4E2 gene. This alteration results from a A to G substitution at nucleotide position 691, causing the arginine (R) at amino acid position 231 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
