Previous GeneCards Identifiers for TPMT Gene
This gene encodes the enzyme that metabolizes thiopurine drugs via S-adenosyl-L-methionine as the S-methyl donor and S-adenosyl-L-homocysteine as a byproduct. Thiopurine drugs such as 6-mercaptopurine are used as chemotherapeutic agents. Genetic polymorphisms that affect this enzymatic activity are correlated with variations in sensitivity and toxicity to such drugs within individuals, causing thiopurine S-methyltransferase deficiency. Related pseudogenes have been identified on chromosomes 3, 18 and X. [provided by RefSeq, Aug 2014]
GeneCards Summary for TPMT Gene
TPMT (Thiopurine S-Methyltransferase) is a Protein Coding gene. Diseases associated with TPMT include 6-Mercaptopurine Sensitivity and Tpmt-Related Altered Drug Metabolism. Among its related pathways are Thiopurine Pathway, Pharmacokinetics/Pharmacodynamics and Porphyrin and chlorophyll metabolism. GO annotations related to this gene include S-adenosylmethionine-dependent methyltransferase activity and thiopurine S-methyltransferase activity.
