The c.464A>G (p.N155S) alteration is located in exon 5 (coding exon 2) of the DTX2 gene. This alteration results from a A to G substitution at nucleotide position 464, causing the asparagine (N) at amino acid position 155 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
