Abstract
Background: The arylamine N-acetyltransferase 2 (NAT2) is a key enzyme in the biotransformation of xenobiotics. NAT2 gene polymorphisms have been associated with the risk of isoniazid hepatotoxicity and these polymorphisms change among different populations.
Aim: The objective of this study is to investigate NAT2 polymorphisms in order to predict the prevalence of NAT2 phenotype in an Algerian population.
Subjects and methods: Genotyping of NAT2 was done using a PCR-RFLP method. Haplotype was analysed using the software package PHASE, version 2.0.
Results: The major haplotypes were NAT2*5B (23.72%), NAT2*6 A (18.61%), NAT2*4 (14.60%) and NAT2*5 F (10%). The average of the expected slow acetylator phenotype was 53%.
Conclusion: Our results suggest that the high frequency of slow acetylator phenotype requires investigation into its possible association with ATDH.
