The best estimate in occurrence probability (95% CI) of the extreme DSW index that falls below the threshold is 1.3% (0.0-3.4%), 0.17% (0.0-0.51%), 0.046% (0.0-0.40%), and 0.11% (0.0-0.40%) for ALL, NAT1, NAT2, and ALLnoENSO, respectively (Fig.
Most of the investigations of NAT as a susceptibility factor in cancer have involved NAT2 polymorphism as it has been better characterized than NAT1 polymorphism (Wohlleb et al., 1990; Hein, 2002).
We deem that this topic appears extremely interesting, but at the same time controversial: it is known that NAT2 enzyme has a critical role in the initial biotransformation of multiple xenobiotic substances (among all aromatic amines and hydrazines) and that several polymorphisms and alleles of its gene characterize the genome of general population (with different distribution in the world) (2).
Alcohol, smoking, and caffeine in relation to fecundability, with effect modification by NAT2. Ann Epidemiol 2011; 21(11): 864-872 [CrossRef]
The NAT2 functions to both activate and deactivate arylamine and hydrazine drugs and carcinogens.
In turn, patient number 1 possessed four polymorphisms connected with drug metabolism (CYP2C19 c.681G>A(p.=), CYP2C9 p.Ile359Leu, NAT2 p.Ile114Thr, and NAT2 p.Arg197Gln), out of which CYP2C9 p.Ile359Leu is of particular importance since it leads to impaired metabolism of widely available nonsteroidal anti-inflammatory drugs [42, 43].

Anti-histone antibodies were elevated at 2.8 units (>1.5 is positive) and her N-acetyltransferase 2 (NAT2) genotype was found to be "intermediate acetylator."
In this respect, a case-control study carried out in European countries investigated polymorphisms with relevance to brain expression and metabolism of substances contained in tobacco smoke and confirmed significant interactions of SNPs in cytochrome P-450 enzyme family genes (GSTM1, GSTP1, and NAT2).

revealed that panel of hypermethylated genes, for example, DCC, CSPG2, and NAT2, was specific to HBV-related HCC [26, 27] and methylation of constitutive androstane receptor (CAR) suppresses CYP2C19 in HBV-associated HCC patients [28].
