LP33553-6   TPMT gene
TPMT (thiopurine methyltransferase) gene mutation determines a patient's ability to metabolize the thiopurine class of drugs. The activity of TPMT is genetically regulated. Source: Regenstrief Institute

LP33553-6   TPMT gene
The TPMT gene (thiopurine S-methyltransferase) [HGNC Gene ID:12014] is located on chromosome 6p22.3. 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] [NCBI Gene ID:7172] Eight known mutations in variants TPMT*2 through *7 account for 90-95% of cases of TPMT deficiency, with four of them, all subtypes of TPMT*3, accounting for 75%. The 8 mutations are as follows: c.238G>C (TPMT*2), c.460G>A and c.719A>G (TPMT*3A), c.460G>A (TPMT*3B), c.719A>G (TPMT*3C), intron 9/exon10 splice junction mutation (TPMT*4), c.146C>T (TPMT*5), c.539A>T (TPMT*6), c.681T>G (TPMT*7).
