Abstract. Thiopurine methyltransferase (TPMT) is implicated in the metabolism of azathioprine.Azathioprine is metabolized and inactivated in the liver and the gastrointestinal tract by several enzymes, the main one being thiopurine methyltransferase (TPMT).

PURPOSE: To assess thiopurine S-methyltransferase (TPMT) phenotype and genotype in patients who were intolerant to treatment with mercaptopurine (MP) or.The TPMT enzyme activity and genotype are tests that are available on a commercial basis for testing.

Changes in the TPMT gene cause TPMT deficiency, which is a reduction in the activity of the TPMT enzyme.

Leukopenia Causes

TPMT mutations have intermediate activity while those homozygous for the mutation.
