Thiopurine methyltransferase test

Alternate Names. TPMT Phenotype. Ordering Information. TPMT activity is predictive of the risk of severe myelosuppression during treatment with azathiopurine, 6-mercaptopurine and related thiopurine compounds. TPMT genotyping is preferred to phenotyping as a first line test.

TPMT activity testing is the most commonly used method to identify patients at risk of serious toxicity. More than 23 variants in the TPMT gene, associated with 18 Aug 2020 The TPMT gene provides instructions for making an enzyme called thiopurine S- methyltransferase (TPMT). This enzyme carries out a specific TPMT catalyzes the S-methylation of thiopurine drugs. Defects in the TPMT gene leads to decreased methylation and decreased inactivation of 6MP leading to This germline genetic test requires physician attestation that patient consent has been received if ordering medical facility is located in AK, DE, FL, GA, IA, MA, It is possible to test patients for TPMT activity before starting treatment with these drugs. Here we review the evidence about such testing, and discuss whether it 1 Jul 2012 J.D.. Thiopurine S-methyltransferase (TPMT) assessment prior to starting thiopurine drug treatment; a pharmacogenomic test whose time has 15 May 2020 The US Food and Drug Administration (FDA) recommends but does not require genetic testing for TPMT.

Changes in the TPMT gene cause TPMT deficiency, which is a reduction in the activity of the TPMT enzyme. Without enough of this enzyme, the body cannot "turn off" thiopurine drugs by metabolizing them into inactive compounds.

The drugs involved 25 Jan 2007 TPMT enzyme measurement is based on the red cell activity levels, which can be distorted following blood transfusion.
