The c.460G>A (p.G154S) alteration is located in exon 2 (coding exon 2) of the METTL13 gene. This alteration results from a G to A substitution at nucleotide position 460, causing the glycine (G) at amino acid position 154 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
