SpletTPMT activity in erythrocytes varies between high, intermediate, and low or none and is controlled by the gene’s allelic variants. Population studies have shown that approximately 90% of the population has high activity, 10% has intermediate activity, and 0.3% has little to no activity [100]. SpletOne Indian study concluded that the identification of TPMT genotype might be important. 15 On the other hand, the heterozygotes received a similar 6-MP dose (41.5 vs 42.92 mg/m 2 /d) in another Indian study, and the study concluded that the identification of TPMT genotype might not be important. 16
