The c.1773C>G (p.S591R) alteration is located in exon 15 (coding exon 15) of the EIF4B gene. This alteration results from a C to G substitution at nucleotide position 1773, causing the serine (S) at amino acid position 591 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
