The c.232G>A (p.D78N) 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 232, causing the aspartic acid (D) at amino acid position 78 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
