Genetic polymorphisms that affect this enzymatic activity are correlated with variations in sensitivity and toxicity to such drugs within individuals. About 1/300 individual is deficient for the enzyme. Pharmacology As well as azathioprine the most common thiopurine drugs are mercaptopurine and thioguanine. What is being tested? A gene called TPMT (thiopurine S-methyltransferase) is involved in metabolizing azathioprine. Thiopurine S-methyltransferase (TPMT) • Cytoplasmic s-methylation of thiopurines – 28 kDa, soluble protein; 245 amino acids • Sites of Metabolism – Heart, Liver, Kidney, Intestines, Pancreas – RBC and WBC • Exhibits genetic polymorphisms – May lead to adverse effects from thiopurine drug use 6-MP 6-MMP The TPMT gene is an enzyme that is involved in the metabolism of thiopurine drugs such as azathioprine, 6-mercaptopurine (6MP) and 6-thioguanine. There are different TPMT gene versions, or variants, and each has a different effect on how well thiopurines are metabolized in the body.

This review gives a practical overview of thiopurine metabolism, the importance of thiopurine S-methyltransferase testing prior to the start of therapy and the The activity level of the TPMT enzyme, or the genetics underlying the enzyme's activity, is tested before thiopurine drug therapy to make sure that individuals treated with the drugs can metabolize them. Examples of thiopurines include azathioprine, mercaptopurine, and thioguanine. Thiopurine-S-methyltransferase (TPMT) is the main enzyme in the complex metabolism of thiopurine-based drugs converting the active compounds into inactive metabolites. While about 89–94% of Caucasian populations show a high enzyme activity approximately 6–11% exhibit an intermediate and 0.3% a low catalytic activity. IMURAN (azathioprine), an immunosuppressive antimetabolite, is available in tablet form for oral administration.

Not in Bone Marrow Thiopurine drugs—6-mercaptopurine (6-MP), 6-thioguanine, and azathioprine—are used in the treatment of leukemia, autoimmune disorders, and solid tumors, as well as in organ transplantations. Among these purine and pyrimidine metabolites, 6-MP is the most prescribed drug for acute lymphoblastic leukemia (ALL).
