Association of cytochrome P450, glutathione S-transferase and N-acetyl transferase 2 gene polymorphisms with incidence of acute myeloid leukemia.

The objective of the paper was to study the association of polymorphisms of phases I and II xenobiotic metabolizing enzyme genes cytochrome P450 (CYP-4501A1*2A, *2B, *2C and *4 alleles, CYP-4502D6*4 allele), glutathione-S-transferase (GSTM1 and GSTT1 null genotypes) and N-acetyl transferase 2 (NAT2*6B and *7A alleles) with the incidence of acute myeloid leukemia (AML) in an eastern Indian population. Polymerase chain reaction and restriction fragment length polymorphism of genomic DNA from peripheral blood cells were used to detect CYP-450 and NAT2 gene polymorphisms in 110 AML patients and 144 racially and geographically matched normal controls. Polymerase chain reaction was also applied to detect GST gene polymorphisms in both groups.
