Ambry Genetics

May 05, 2023

The c.334A>G (p.I112V) alteration is located in exon 3 (coding exon 3) of the EIF4B gene. This alteration results from a A to G substitution at nucleotide position 334, causing the isoleucine (I) at amino acid position 112 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
