The c.1385C>T (p.S462F) alteration is located in exon 11 (coding exon 11) of the EIF4B gene. This alteration results from a C to T substitution at nucleotide position 1385, causing the serine (S) at amino acid position 462 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
