Ambry Genetics

Nov 10, 2022

The c.202A>G (p.I68V) 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 202, causing the isoleucine (I) at amino acid position 68 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
