The c.983C>T (p.P328L) alteration is located in exon 9 (coding exon 9) of the EIF4B gene. This alteration results from a C to T substitution at nucleotide position 983, causing the proline (P) at amino acid position 328 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
