NCIt definition : Dihydropyrimidine dehydrogenase [NADP( )] (1025 aa, 111 kDa) is encoded by the human
DPYD gene. This protein is involved in the degradation of pyrimidines.;
NCIt note : Dihydropyrimidine dehydrogenase [NADP( )] can catabolize fluorouracil-based chemotherapy
drugs. Therefore the expression and activity levels of this enzyme affect therapeutic
efficacy and toxicity in patients receiving this type of chemotherapy.;
