The c.757G>A (p.D253N) alteration is located in exon 4 (coding exon 4) of the YTHDC1 gene. This alteration results from a G to A substitution at nucleotide position 757, causing the aspartic acid (D) at amino acid position 253 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
