The c.1253C>G (p.S418W) alteration is located in exon 10 (coding exon 10) of the EIF4B gene. This alteration results from a C to G substitution at nucleotide position 1253, causing the serine (S) at amino acid position 418 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
