Ambry Genetics

May 17, 2023

The c.1792G>C (p.V598L) alteration is located in exon 15 (coding exon 15) of the EIF4B gene. This alteration results from a G to C substitution at nucleotide position 1792, causing the valine (V) at amino acid position 598 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
