dc.description.abstract | The xenobiotic metabolizing enzymes N-acetyltransferases (NATs) are important for the biotransformation and/or bioactivation of drugs and carcinogens. NATs are coded for in humans by two distinct genes, designated NAT1 and NAT2. NAT1, which was originally thought to be monomorphic, was recently reported to exhibit variation in human populations. Recent studies suggested that a genetic polymorphism of NAT1 may be associated with colorectal cancer risk. The distributions of NAT1 allele and genotype frequencies in unrelated individuals among Indian (n = 140), Malay (n = 122) and Chinese (n = 181) populations in Singapore were characterized by polymerase chain reaction-restriction fragment length polymorphism and allele-specific-polymerase chain reaction. The allelic frequencies of NAT1*3, NAT1*4, NAT1*10 and NAT1*11 among Indians were 0.3, 0.5, 0.17 and 0.27 and 0.02, respectively. The corresponding NAT1 allelic frequencies in Malays were 0.29, 0,30, 0.33 and 0.02, respectively, and were similar to those in Chinese in the region. The allelic frequencies of NAT1*3, NAT1*4, NAT1*10 and NAT1*11 among Chinese were 0.33, 0.35, 0.30 and 0.02, respectively. These findings are of importance for the determination of cancer risk in these populations. In addition, nucleotide changes at positions 350-351 (GG to CC) and 497-449 (GGG to CCC) of the NAT1 gene were not found in the alleles of the populations studied. | |
