单词 | orotic aciduria |
释义 | orotic acidurian. Medicine. Excessive excretion of orotic acid in the urine; spec. a genetic (autosomal recessive) disorder of pyrimidine metabolism in humans, in which deficient activity of the enzyme uridine monophosphate synthase, which catalyses the two-step conversion of orotic acid to uridine monophosphate, results in the accumulation of orotic acid and in megaloblastic anaemia that responds to uridine administration.
