Pharmacogenetics of thiopurine S-methyltransferase and thiopurine therapy.
Most medications exhibit wide interpatient variability in their efficacy and toxicity. For many medications, these interindividual differences result in part from polymorphisms in genes encoding drug-metabolizing enzymes, drug transporters, and/or drug targets (eg, receptors, enzymes). Pharmacogenomics is a burgeoning field aimed at elucidating the genetic basis of differences in drug efficacy ...
متن کاملThiopurine S-methyltransferase and Pemphigus Vulgaris: A Phenotype-Genotype Study
Background & Objective: Thiopurine drugs are considered as a treatment modality in various autoimmune disorders including pemphigus vulgaris (PV). These drugs are metabolized by an enzyme “Thiopurine S-methyl transferase” (TPMT). Various variants of this enzyme may have decreased activity lead...
متن کاملClinical pharmacogenomics of thiopurine S-methyltransferase.
Thiopurine methyltransferase (TPMT) catalyzes the S-methylation of thiopurine drugs such as 6-mercaptopurine (6-MP), thioguanine and azathioprine (AZA). These drugs are used to treat conditions such as acute lymphoblastic leukemia, inflammatory bowel disease, rheumatoid arthritis, and organ transplant rejection. This review highlights the polymorphisms of TPMT gene and their clinical impact on ...
متن کاملHigh-throughput genotyping of thiopurine S-methyltransferase by denaturing HPLC.
BACKGROUND The thiopurine S:-methyltransferase (TPMT) genetic polymorphism has a significant clinical impact on the toxicity of thiopurine drugs, which are used in the treatment of leukemia and as immunosuppressants. To date, 10 mutant alleles are known that are associated with intermediate or low TPMT activity. To facilitate rapid screening of clinically relevant TPMT mutations, we developed a...
متن کاملAssessment of Thiopurine–based drugs according to Thiopurine S-methyltransferase genotype in patients with Acute Lymphoblastic Leukemia
For the past half century, thiopurines have earned themselves a reputation as effective anti-cancer and immunosuppressive drugs. Thiopurine S-methyltransferase (TPMT) is involved in the metabolism of all thiopurines and is one of the main enzymes that inactivates mercaptopurine. 6-MP is now used as a combination therapies for maintenance therapy of children with acute lymphocytic leukemia (A...
