title: Polymorphisms in NAT2 gene and atherosclerosis in an Algerian population.
abstract: OBJECTIVE
  The etiology of atherosclerosis is multifactorial. Genetic and environmental factors are involved in the development of atherosclerosis. Human arylamine N-acetyltransferase 2 (NAT2) is an important metabolizing enzyme that exhibits genetic polymorphisms and modifies individual response and/or toxicity to many xenobiotics. We undertook this study to investigate the NAT2 polymorphisms in patients with atherosclerosis.
  
  
  METHODS
  Genotyping for NAT2 alleles was performed using polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) in 285 Algerian patients with atherosclerosis and 286 controls.
  
  
  RESULTS
  There was no association between NAT2 polymorphisms and atherosclerosis risk. However, the haplotype NAT2(*)5F decreased susceptibility to the disease (p = 0.005, OR = 0.55, 95% CI = 0.37-0.84). The frequency of the slow acetylator phenotype was approximately 50% in both cases and controls.
  
  
  CONCLUSIONS
  These results suggest that NAT2 polymorphisms may not be involved in the pathogenesis of atherosclerosis.
