TPMT3 : Thiopurine methyltransferase (TPMT) deficiency is a condition in which patients treated with standard doses of azathioprine (AZA, Imuran), 6-mercaptopurine (6-MP, Purinethol), or 6-thioguanine (6-TG, Thioguanine Tabloid) may develop life-threatening myelosuppression or severe hematopoietic toxicity. The metabolic conversion of AZA, 6-MP, or 6-TG to purine nucleotides and the subsequent

2020-05-15 Thiopurine S-Methyltransferase (TPMT) Genotype - Thiopurine S-methyltransferase (TPMT; S-adenosyl-L-methionine:thiopurine S-methyltransferase) catalyzes thiopurine S-methylation, an important metabolic pathway for antineoplastic and immunosuppressive drugs. In the US, 11% of the population show intermediate TPMT activity, and approximately 1 in 300 have TPMT deficiency. Thiopurine S-methyltransferase (TPMT) deficiency is a condition characterized by significantly reduced activity of an enzyme that helps the body process drugs called thiopurines. These drugs, which include 6-thioguanine, 6-mercaptopurine, and azathioprine, inhibit (suppress) the body's immune system. Test Code TPMTA Thiopurine Methyltransferase, RBC Clinical Indications. Phenotype test to assess risk for severe myelosuppression with standard dosing of thiopurine drugs.

2018-02-22 · Normal TPMT activity: 25-65 U/mL - Individuals are predicted to be at low risk of bone marrow toxicity as a consequence of standard thiopurine therapy; no dose adjustment is recommended. Abnormal TPMT activity: 25 U/mL - Individuals are predicted to be at high risk of bone marrow toxicity as a consequence of standard thiopurine dosing; a dose reduction and therapeutic monitoring is recommended.

Allopurinol inhibits thiopurine S-methyltransferase, which can increase the utility of 6-MP. Diagnostic use. Measurement of TPMT activity is encouraged prior to commencing the treatment of patients with thiopurine drugs such as azathioprine, 6-mercaptopurine and 6-thioguanine. Azathioprine has been in use for decades as an immunosuppressant treatment for various autoimmune diseases.

Thiopurine S-methyltransferase (TPMT) is involved in the metabolism of thiopurine drugs. Patients that due to genetic variation lack this enzyme or have lower levels than normal, can be adversely affected if normal doses of thiopurines are prescribed.
