G-to-T transversion at codon 249 of the p53 gene has been shown to be specifically associated with human hepatocellular carcinomas, particularly that subset associated with exposure to the chemical hepatocarcinogen aflatoxin B,. We surveyed 47 North American adult hepatocellular carcinomas and three

Environmental carcinogens often induce specific mutations in the p53 gene, apparent in tumors. The relation between aflatoxin B1(AFB1)-related hepatocellular carcinomas (HCCs) and hot spot at codon 249 of the p53 gene has received a great deal of attention, but its significance is still controversia
## Abstract In hepatocellular carcinoma (HCC), hotspot mutation in codon 249 of the __p__53 gene has been associated with exposure to aflatoxin B1 (AFB1). While the polymorphism of DNA repair gene Xβray repair crossβcomplementary group 1 (XRCC1) Arg399Gln may be related with AFB1βDNA adducts and ge
