The risk of lung and urinary bladder cancers was reported to be increased in individuals who carried high risk genotypes in either cytochrome P450 (CYP)1A1, CYP2E1 or glutathione S-transferase (GST)M1, and the combined genotype of both CYP1A1 and GSTM1 enzymes have an enhanced tendency of risk to lung cancer more significantly.

The cytochromes P-450 (CYPs) are responsible for the activation mechanism, and polymorphisms of the CYPs (CYP1A1, CYP2D6, and possibly CYP2E1) are known to be related to increased susceptibility to smoking related Kreyberg type I lung cancer.
