Mar 07, 2023

The c.389G>A (p.C130Y) alteration is located in exon 4 (coding exon 3) of the METTL6 gene. This alteration results from a G to A substitution at nucleotide position 389, causing the cysteine (C) at amino acid position 130 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
