abstract：:Cytochrome P450 2A6 (CYP2A6) is an enzyme involved in the metabolism of tobacco carcinogens, which are important risk factors in lung cancer. We and others have previously reported that CYP2A6*4, a whole-gene deletion polymorphism, is associated with lower risk of lung cancer than the wild-type allele. However, the ge...
