The c.253A>G (p.K85E) alteration is located in exon 2 (coding exon 2) of the METTL13 gene. This alteration results from a A to G substitution at nucleotide position 253, causing the lysine (K) at amino acid position 85 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
