Abstract
Genetic polymorphisms are identified in the human UGT2B4, UGT2B7 and UGT2B15 genes that alter UGT2B activity. Nucleic acids comprising the polymorphic sequences are used to screen patients for altered metabolism for UGT2B substrates, potential drug-drug interactions, and adverse/side effects, as well as diseases that result from environmental or occupational exposure to toxins. The nucleic acids are used to establish animal, cell and in vitro models for drug metabolism.
