Ambry Genetics

Feb 08, 2023

The c.1525G>T (p.G509W) alteration is located in exon 12 (coding exon 12) of the EIF4B gene. This alteration results from a G to T substitution at nucleotide position 1525, causing the glycine (G) at amino acid position 509 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
