Additional Information:

Clinical Description OMIM The antituberculosis agent isoniazid (INH) is rendered therapeutically inactive by acetylation. Most or perhaps all populations of the world are polymorphic for 'rapid inactivation' versus 'slow inactivation.' As shown by the study of Evans et al. (1960), the ...
Molecular genetics OMIM The highly homologous human genes for N-acetyltransferase, NAT1 and NAT2, appear to code for the genetically invariant and variant NAT proteins, respectively. NAT1, which is responsible for N-acetylation of certain arylamine drugs, displays no genetic variation, whereas the ...
Population genetics OMIM To investigate the role of population history and natural selection in shaping variation in the closely clustered NAT1 and NAT2 genes on chromosome 8p, Patin et al. (2006) characterized genetic diversity through the resequencing and genotyping of NAT1, ...
