SpletTPMT*3A had more than 200-fold reduced enzyme activity than the wild type. While the TPMT*3C mutant allele, the most common mutant allele in Asia and Africa, contains an SNP (A719G in exon 10), it produces intermediate enzyme activity compared with the wild type. 24–26 The variation of TPMT enzyme activity in mutant alleles caused a ...

SpletA reduction in 6-MP dose is recommended for TPMT heterozygotes because an increased risk of hematologic toxicity was observed in comparison to those with wild-type TPMT in many American and European studies. 6–12 However, TPMT enzyme activity differs between mutant alleles. SpletThree of the six with severe GI toxicity were heterozygous for the TPMT*3A allele, while the remainder possessed the wild-type TPMT allele. The association between the TPMT … Spletwild-type patients, only about 30–60% of TPMT heterozygotes cannot tolerate full doses of mercaptopurine or azathioprine.8,10,11 Good thiopurine tolerance in some heterozygotes may be because, although they have higher TGNs than homozygous wild-type pa-tients, they have lower concentrations (and, thus, fewer toxic effects) mylo thg elearning
