{"Azathioprine can be affected by a patient's TPMT and NUDT15 phenotype. This patient is predicted to be a TPMT poor metabolizer and NUDT15 poor metabolizer. This patient is at high risk for life threatening myelosuppression with normal doses of azathioprine. Consider alternative non-thiopurine immunosuppressant therapy. Please consult a clinical pharmacist for more information."}
