Genetic polymorphisms of arylamine N-acetyltransferases 1 and 2 and the likelihood of developing pediatric acute lymphoblastic leukemia Article uri icon

abstract

  • Acute lymphoblastic leukemia (ALL) is one of the main causes of death in children and is associated with both genetic susceptibility and environmental factors. Genes encoding the arylamine N-acetyltransferases 1 and 2 (NAT1 and NAT2) isoenzymes are highly polymorphic among populations. Single-nucleotide polymorphism analysis was performed by real-time polymerase chain reaction from the genomic DNA of 225 healthy subjects and 57 children with ALL diagnoses. Significant associations were found between the development of ALL and the presence of the haplotypes NAT1*3 (Odds ratio [OR], 2.1), NAT1*4 (OR, 1.92), NAT2*6B (OR, 3.30), NAT2*6J (OR, 3.25) and NAT2*7A (OR, 2.45) and the NAT1 rapid (OR, 6.69) and NAT2 slow phenotypes (OR, 2.95). Our results indicate that haplotypes that provide rapid NAT1 and slow NAT2 acetylating phenotypes may influence the development of ALL in children. © 2017, © 2017 Informa UK Limited, trading as Taylor %26 Francis Group.
