The c.710T>G (p.L237R) alteration is located in exon 4 (coding exon 3) of the NAT16 gene. This alteration results from a T to G substitution at nucleotide position 710, causing the leucine (L) at amino acid position 237 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
