High-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 کاملThiopurine methyltransferase (TPMT) genotyping to predict myelosuppression risk
Azathioprine (AZA), 6-mercaptopurine (6-MP), and thioguanine (TG) are thiopurine drugs. These agents are indicated for the treatment of various diseases including hematologic malignancies, inflammatory bowel disease (IBD), rheumatoid arthritis, and as immunosuppressants in solid organ transplants. Thiopurine drugs are metabolized, in part, by thiopurine methyltransferase (TPMT). TPMT displays g...
متن کاملThiopurine methyltransferase genotyping in Palestinian childhood acute lymphoblastic leukemia patients
BACKGROUND The genetic polymorphism of thiopurine methyltransferase (TPMT) is well characterized in most populations. Four common polymorphic alleles are associated with impaired activity of the enzyme. These are TPMT*2 (238G>C), TPMT*3B (c.460G>A), TPMT*3A (c.460G>A and c.719A>G) and TPMT*3C (c.719A>G). The aim of the present study was to determine the frequency of TPMT polymorphisms and their...
متن کاملPharmacogenetics 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 pharmacogenetics: clinical and molecular studies of thiopurine methyltransferase.
Thiopurine drugs are used to treat patients with neoplasia and autoimmune disease as well as transplant recipients. These agents are metabolized, in part, by S-methylation catalyzed by thiopurine methyltransferase (TPMT). The discovery nearly two decades ago that levels of TPMT activity in human tissues are controlled by a common genetic polymorphism led to one of the best examples of the poten...
