The c.377A>G (p.Y126C) alteration is located in exon 3 (coding exon 3) of the YTHDC1 gene. This alteration results from a A to G substitution at nucleotide position 377, causing the tyrosine (Y) at amino acid position 126 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
