The tests for thiopurine methyltransferase (TPMT) enzyme activity or its underlying genetics are measured in people who are about to start treatment with a thiopurine drug. One or the other of these tests is used to identify individuals at risk of developing severe side effects from thiopurine therapy. Thiopurine methyltransferase or thiopurine S-methyltransferase (TPMT) is an enzyme that in humans is encoded by the TPMT gene. A pseudogene for this locus is located on chromosome 18q. The TPMT blood test is used to test the activity of the thiopurine methyltransferase enzyme. Sometimes the test is ordered to measure the genetic structures that are in place supporting the TPMT activity instead.

La thiopurine S-méthyltranférase (TPMT) est une enzyme qui assure le catabolisme des thiopurines (azothioprine, 6-mercaptopurine, thioguanine) qui inhibent le système immunitaire et qui sont utilisées dans le traitement de certaines pathologies malignes hématologiques, de maladies auto-immunes (maladie de Crohn, polyarthrite rhumatoïde), et après transplantation d'organe. 2012-08-29 · Thiopurine S-methyltransferase (TPMT) is an enzyme that the body uses to break down thiopurine drugs.

TPMT3 : Detection of individuals with low thiopurine methyltransferase (TPMT) activity who are at risk for excessive myelosuppression or severe hematopoietic toxicity when taking thiopurine drugs   Detection of individuals with hyperactive TPMT activity who have therapeutic resistance to thiopurine drugs and may develop hepatotoxicity if treated with these drugs

Thiopurine methyltransferase 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 

Thiopurine methyltransferase test

Thiopurine Methyltransferase Phenotype. 6-mercaptopurine and related thiopurine compounds. TPMT genotyping is preferred to phenotyping as a first line test. 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. This is a next generation sequencing (NGS) test appropriate for individuals with clinical signs and symptoms, suspicion of, or family history of Thiopurine S-Methyltransferase Deficiency.

Special Instructions Library of PDFs including pertinent information and forms related to the test Avoid gel-separator tubes. Adult minimum 1.0 mL. Pediatric: 1.0 mL whole blood,0.5 mL minimum.Falsely low TPMT activity is observed in patients being treatedwith aminosalicylates.

· What is being tested? A gene called TPMT (thiopurine S-methyltransferase) is  Thiopurine methyltransferase (TPMT) is an enzyme that breaks down ( metabolizes) thiopurines. Thiopurines include three medications: 6- mercaptopurine  TPMT Testing for Thiopurine Drug. Response. MOL.TS.229.A Genetic variants in the TPMT gene are associated with lower enzyme activity, leading to an  Overview: 6-mercaptopurine is recognizes the first thiopurine analog determined to show clinical "Genetic testing is available for several TPMT variant alleles.

Uses for Test • Identify patients who are at risk for abnormal drug metabolism and toxicity from thiopurine drugs metabolized by thiopurine S-methyltransferase (TPMT), including azathioprine, 6-mercaptopurine, and thioguanine. • Identify genotypes shown to have a drug-gene variant relationship.
