The c.616C>G (p.R206G) alteration is located in exon 9 (coding exon 7) of the EIF4E1B gene. This alteration results from a C to G substitution at nucleotide position 616, causing the arginine (R) at amino acid position 206 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
