WebDec 13, 2024 · 7-12 days. Clinical Use. Help prevent hepatotoxicity from thiopurine therapy. This test helps identify individuals at increased risk of hepatotoxicity from thiopurine dose escalation. Patients with a TMPT activity of 4-12 nmol 6-MMP/hr/mL RBC (heterozygote/low metabolizer) are at increased risk and may require a lower dose of thiopurine drug. WebJul 16, 2024 · Polymorphisms of thiopurine methyltransferase enzyme (TPMT) that result in low enzymatic activity have been associated with an increased risk of myelotoxicity, especially in Caucasians; however, in Asians it is assumed that the variants of nudix hydrolase 15 (NUDT15) are more relevant in the development of toxicity.

WebThiopurine methyl transferase (TPMT) is an enzyme catalysing the methylation of 6-MP, competing with xanthine oxidase (XO) and hypoxanthine guanine phosphoribosyl transferase (HGPRT) to determine the amount of 6-MP … WebTPMT is the primary metabolic route for inactivation of thiopurine drugs in the bone marrow. When TPMT activity is low, it is predicted that proportionately more 6-mercaptopurine can … WebApr 15, 2024 · 6-MP, as parent molecule or as a metabolite of AZA, can also undergo methylation by the enzyme thiopurine-S-methyltransferase (TPMT) forming 6-methylmercaptopurine (6-MMP, inactive metabolite). TPMT can also methylate 6-TIMP to 6-methyl TIMP and lead to formation of 6-MMP ribonucleotides (active metabolite, 6 … classic vw car shows 2023
