Dihydropryrimidine dehydrogenase


General
  Clinical Use: The protein dihydropyrimidine dehydrogenase is involved in the breakdown of various drugs. Variants in the protein's gene, DPYD, can slow the rate at which certain drugs are broken down.
The drugs involved are 5-fluorouracil (5FU), capecitabine and tegafur. A patient with such a variant may be at risk of bone marrow toxicity from the medication.
The laboratory report describes the gene variants detected in a patient, and the implications regarding drug choice or dose according to current evidence-based guidelines.
