The c.56G>A (p.S19N) alteration is located in exon 1 (coding exon 1) of the METTL21C gene. This alteration results from a G to A substitution at nucleotide position 56, causing the serine (S) at amino acid position 19 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
