The c.230A>G (p.E77G) alteration is located in exon 3 (coding exon 2) of the METTL6 gene. This alteration results from a A to G substitution at nucleotide position 230, causing the glutamic acid (E) at amino acid position 77 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
