PROJECT SUMMARY
Dihydropyrimidine dehydrogenase (DPD) deficiency, caused by mutations within DPYD, has been
studied mostly in the context of 5-fluorouracil (5-FU) toxicity and its role as a pharmacogene. However, a rare
pediatric disorder with severe early onset symptoms, pediatric DPD deficiency, is also linked to genetic
variation within DPYD.…
