The c.377A>G (p.E126G) alteration is located in exon 5 (coding exon 3) of the NKIRAS1 gene. This alteration results from a A to G substitution at nucleotide position 377, causing the glutamic acid (E) at amino acid position 126 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
