Summary The protein encoded by this gene is a pyrimidine catabolic enzyme and the initial and rate-limiting factor in the pathway of uracil and thymidine catabolism. Mutations in this gene result in dihydropyrimidine dehydrogenase deficiency, an error in pyrimidine metabolism associated with thymine-uraciluria and an increased risk of toxicity in cancer patients receiving 5-fluorouracil chemotherapy. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009].

GeneRIFs: Gene References Into Functions What's a GeneRIF?

What is the normal function of the DPYD gene?

The DPYD gene provides instructions for making an enzyme called dihydropyrimidine dehydrogenase, which is involved in the breakdown of molecules called uracil and thymine when they are not needed. Uracil and thymine are pyrimidines, which are one type of nucleotide. Nucleotides are building blocks of DNA, its chemical cousin RNA, and molecules such as ATP and GTP that serve as energy sources in the cell.

Dihydropyrimidine dehydrogenase is involved in the first step of the breakdown of pyrimidines. This enzyme converts uracil to another molecule called 5,6-dihydrouracil and converts thymine to 5,6-dihydrothymine. The molecules created when pyrimidines are broken down are excreted by the body or used in other cellular processes.
