"WebThiopurine S-methyltransferase (TPMT) is a cytosolic enzyme that inactivates thiopurine drugs such as 6-mercaptopurine and azathioprine through methylation. There is substantial variability in TPMT enzyme activity between individuals, and it has been found that this variability can be attributed to polymorphisms in the TPMT gene.
