The c.413A>G (p.E138G) alteration is located in exon 3 (coding exon 2) of the DDIT4 gene. This alteration results from a A to G substitution at nucleotide position 413, causing the glutamic acid (E) at amino acid position 138 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
