Is there a relation between Murine double minute 2 T309G polymorphism and lung cancer risk in the Turkish population?
Abstract
Introduction: Association between Murine double minute 2 T309G polymorphism and lung cancer risk has been investigated in several populations, but results of these studies are inconsistent. We aimed to investigate the effect of Murine double minute 2 T309G polymorphism on development of lung cancer in a Turkish population. Methods: Total 200 subjects including 100 patients and 100 controls were analyzed and used polymerase chain reaction and restriction fragment length polymorphism methods for genotyping analysis of the polymorphism. Results: We found that smokers compared with nonsmokers have approximately eight fold higher lung cancer risk [p = 0.0001, OR = 8.27 (4.02-16.9)]. Frequency of GG genotype was higher in patients than in controls, but this ratio was not significant (chi(2) = 3.5, p = 0.17). Genotype distribution of the polymorphism was not different neither patients with non-small cell lung cancer nor patients with small cell lung cancer (chi(2) = 2.89, p = 0.57). We analyzed together with demographic feature (except smoking habit), clinicopathological findings and genotype frequencies of this polymorphism, and any association with lung cancer risk was not obtained. Conclusion: No correlation between Murine double minute 2 T309G polymorphism and lung cancer risk was detected in this Turkish population.
