The c.481G>A (p.D161N) alteration is located in exon 6 (coding exon 6) of the NT5DC1 gene. This alteration results from a G to A substitution at nucleotide position 481, causing the aspartic acid (D) at amino acid position 161 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
