Abstract:Objective To investigate the relationship between the Reprimo gene 3'-untranslated region 839 polymorphism and lung cancer. Methods Genotyping was performed with MightyAmp DNA Polymerase, a number of 36 lung cancer cases and 23 control cases were genotyped. The results of investigation were analyzed with χ2 test, Logistic regression analysis and Armitage's trend test. Results According to Hardy-Weinberg equilibrium detection, Reprimo 839 G>C genotype observation (theory) frequency was 0, 22, 1 (5.26, 11.48, 6.26) in the control group (with statistically significant difference, P = 0.000) and 6, 29, 1 (11.67, 17.65, 6.67) in the cancer group (with statistically significant difference, P = 0.000). Analyzed by Logistic regression analysis, gene polymorphism and age were risk factors, and there were no possible interactions among gene polymorphism, age, smoking status and lung cancer (P > 0.05). Armitage's trend test revealed no statistically significant correlation between 839 G>C polymorphism and susceptibility to lung cancer (χ2 = 3.56, P = 0.059). Conclusions This study indicates that there is a correlation between the Reprimo gene 3'-untranslated region 839 G>C polymorphism and lung cancer.
