NAT1 gene structure with three types of transcripts and 5′UTR splice variants [7]. P1, P2 and P3 represent three promoter regions. The consensus poly-adenylation signal sites polyA1, polyA2, and polyA3 produce short, major and long 3′UTR isoforms, respectively. F1, F2, R1, R2, IIF and IIIF indicate the location and direction of PCR primers.
