title: Polymorphism of the p53 gene within the codon 72 in lung cancer patients.
abstract: We tested the codon 72 single nucleotide polymorphism (SNP) of the tumor suppressor gene p53 for association with lung cancer. In our hospital-based case-control study, 168 lung cancer patients (134 males and 34 females) and 148 controls without malignant diseases were recruited. The genotype characteristics were determined by PCR-based RFLP method using DNA extracted from peripheral blood. Only in lung cancer patients but not in the controls we found both significant decrease of A1 allele of the p53 codon 72 (p=0.024, OR 0.56, 95% CI 0.43-0.72) and A1/A1 homozygous genotype (p=0.006, OR 0.27,95% CI 0.15-0.51). The results of this study suggest a protective effect of A1 allele against lung cancer.
