Thiopurine Methyltransferase TPMT – *2 *3A *3B *3C Genotyping Test
At DNA Labs UAE, we offer the Thiopurine Methyltransferase TPMT – *2 *3A *3B *3C Genotyping Test to help determine the appropriate dosage of thiopurine drugs for individual patients. This test can be done with a doctor’s prescription and is particularly useful for those undergoing treatment for autoimmune and inflammatory conditions.
Test Details
The Thiopurine Methyltransferase (TPMT) genotyping test analyzes specific genetic variants in the TPMT gene. TPMT is an enzyme involved in the metabolism of thiopurine drugs, commonly used in the treatment of various conditions. By identifying genetic variants such as TPMT*2, TPMT*3A, TPMT*3B, and TPMT*3C, we can assess the activity of the TPMT enzyme and determine the appropriate dosage of thiopurine drugs for each patient.
TPMT*2
This variant is characterized by a single nucleotide change in the TPMT gene, resulting in reduced TPMT enzyme activity. Individuals with this variant are at an increased risk of developing severe side effects when treated with thiopurine drugs.
TPMT*3A
This variant involves a deletion of two nucleotides in the TPMT gene, leading to a non-functional TPMT enzyme. Individuals with this variant have extremely low TPMT enzyme activity and are at a very high risk of experiencing severe toxicity if treated with thiopurine drugs.
TPMT*3B
This variant is caused by a single nucleotide change in the TPMT gene, resulting in reduced TPMT enzyme activity. Individuals with this variant have a moderately decreased TPMT enzyme activity and may require lower doses of thiopurine drugs to avoid toxicity.
TPMT*3C
This variant is characterized by a single nucleotide change in the TPMT gene, leading to reduced TPMT enzyme activity. Individuals with this variant have a slightly decreased TPMT enzyme activity and may require lower doses of thiopurine drugs to minimize the risk of toxicity.

Test Details |
Thiopurine methyltransferase (TPMT) genotyping refers to the analysis of specific genetic variants in the TPMT gene. TPMT is an enzyme involved in the metabolism of thiopurine drugs, such as azathioprine and mercaptopurine, which are commonly used in the treatment of various autoimmune and inflammatory conditions. There are several genetic variants in the TPMT gene that can affect the activity of the TPMT enzyme. The most common variants that are genotyped include TPMT*2, TPMT*3A, TPMT*3B, and TPMT*3C. – TPMT*2: This variant is characterized by a single nucleotide change in the TPMT gene, resulting in reduced TPMT enzyme activity. Individuals with this variant are at an increased risk of developing severe side effects when treated with thiopurine drugs. – TPMT*3A: This variant involves a deletion of two nucleotides in the TPMT gene, leading to a non-functional TPMT enzyme. Individuals with this variant have extremely low TPMT enzyme activity and are at a very high risk of experiencing severe toxicity if treated with thiopurine drugs. – TPMT*3B: This variant is caused by a single nucleotide change in the TPMT gene, resulting in reduced TPMT enzyme activity. Individuals with this variant have a moderately decreased TPMT enzyme activity and may require lower doses of thiopurine drugs to avoid toxicity. – TPMT*3C: This variant is characterized by a single nucleotide change in the TPMT gene, leading to reduced TPMT enzyme activity. Individuals with this variant have a slightly decreased TPMT enzyme activity and may require lower doses of thiopurine drugs to minimize the risk of toxicity. Genotyping for these TPMT variants is typically done using a molecular genetic testing method, such as polymerase chain reaction (PCR) or DNA sequencing. This information can help healthcare providers determine the appropriate dosage of thiopurine drugs for individual patients, minimizing the risk of severe side effects. |
