Mar 14, 2023

The c.809G>T (p.R270L) alteration is located in exon 7 (coding exon 5) of the METTL15 gene. This alteration results from a G to T substitution at nucleotide position 809, causing the arginine (R) at amino acid position 270 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
