The c.392A>T (p.K131M) alteration is located in exon 4 (coding exon 3) of the METTL6 gene. This alteration results from a A to T substitution at nucleotide position 392, causing the lysine (K) at amino acid position 131 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
