The c.677C>T (p.A226V) alteration is located in exon 9 (coding exon 7) of the EIF4E1B gene. This alteration results from a C to T substitution at nucleotide position 677, causing the alanine (A) at amino acid position 226 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
