Research output: Contribution to journalArticlepeer-review


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 B1. We surveyed 47 North American adult hepatocellular carcinomas and three childhood liver tumors for codon 249 mutation. We report here a case of childhood hepatoblastoma in a patient, without known exposure to aflatoxin B1 or hepatitis B or C virus, whose tumor had a mutation at codon 249 involving G-to-T transversion.
