WebTPMT: THE BASICS. TPMT activity in the red blood cell and other human tissues is under the control of a common genetic polymorphism. 20 The frequency distribution of TPMT activity in Caucasian populations is trimodal: approximately 89% of the population have high enzyme activity and are homozygous for the wild-type allele (TPMT H), 11% inherit … WebA cut-off value of 9 U/ml pRBC was used to distinguish intermediate TPMT enzyme activity from high TPMT enzyme activity. Results: Sequencing of the real-time RT-PCR amplicon proved that the method was specific for the TPMT cDNA, without co-amplification of the highly similar TPMT processed pseudogene.
