WebThiopurine methyltransferase (TPMT) catalyzes the S-methylation of thiopurine drugs. Individual variation in the toxicity and therapeutic efficacy of these drugs is associated with a common genetic polymorphism that controls levels of TPMT activity and immunoreactive protein in human tissues. WebThe results show that high TPMT enzyme activity is not the major reason for preferential 6-MMP production in most patients with a high metabolite ratio. This suggests that there …

WebWe recommend initiation of azathioprine therapy on the basis of the initial measurement of TPMT activity: an initial dosage of 100 mg/d for a 75-kg person (or 1.5-2 mg/kg daily) for patients with high TPMT levels in the homozygous wild-type range (14.5 U/mL of RBCs) and 25 mg/d for patients with TPMT levels in the heterozygous range. WebThiopurine S-methyltransferase deficiency patients have a genetic change in either one or both copies of the TPMT gene that causes reduced enzyme activity and difficulties breaking down thiopurine drugs. Affected individuals are at a high risk of experiencing bone marrow damage if they take thiopurine drugs. Many patients recover from the bone ...
