The c.608G>C (p.S203T) alteration is located in exon 5 (coding exon 4) of the METTL6 gene. This alteration results from a G to C substitution at nucleotide position 608, causing the serine (S) at amino acid position 203 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
