The c.908T>C (p.L303P) alteration is located in exon 7 (coding exon 5) of the METTL15 gene. This alteration results from a T to C substitution at nucleotide position 908, causing the leucine (L) at amino acid position 303 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
