{"6-mercaptopurine can be affected by a patient's TPMT and NUDT15 phenotype. This patient is predicted to be a TPMT normal metabolizer; there is no reason to selectively adjust the dose of this medication based on the TPMT result. However, NUDT15 phenotype could not be assigned based on genotyping. Monitor closely for toxicity. Please consult a clinical pharmacist for more information."}
