NCIt definition : Human DHODH wild-type allele is located within 16q22 and is approximately 16 kb in
length. This allele, which encodes dihydroorotate dehydrogenase, mitochondrial protein,
is involved in de novo pyrimidine biosynthesis.;
NCIt note : Dihydroorotate dehydrogenase is a drug target in the pyrimidine biosynthetic pathway.
Mutations in the DHODH gene that affect the expression or catalytic activity of this
enzyme may alter the efficacy of chemotherapy.;
