The latest TPMT and NUDT15... SpletThe concordance between TPMT genetics and phenotypes is slightly less than 100%. TPMT activity (phenotype) can be measured directly in red blood cell membranes. Alternatively (e.g., in patients who have undergone blood transfusions), genetic polymorphisms can be identified by polymerase chain reaction. Guidelines for TPMT …
