  1. 1c.481C>T is a silent mutation associated also with NAT*12C (c.481C>T+ c.803A>G) which is a rapid allele (see Hein et al. 2000, [1])
  2. 2 For the calculation of ORs for individual genotypes, NAT2*4/*4 [c. 481CC + c.590 GG + c.857 GG] was used as reference and all corresponding odds ratios were determined with respect to this reference.
