{"This patient is predicted to be a NUDT15 normal metabolizer; there is no reason to selectively adjust the dose of this medication based on the NUDT15 result. However, TPMT phenotype could not be assigned based on genotyping performed. Consider evaluating TPMT erythrocyte activity to assess TPMT phenotype. Erythrocyte TPMT activity test results can be falsely low at diagnosis of leukemia and is unreliable in the case of recent red blood cell transfusions. If thiopurines are required and TPMT status is unknown, monitor closely for toxicity."}
