MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]

Nature of Mutation

DNA sequencing using the SOLiD technique identified a T to A transversion at base pair 118507052 in the Genbank genomic region NC_000069 (Build 37.1) for the Dpyd gene on Chromosome 3 (GTGAGTACGA ->GAGAGTACGA). The mutation is located within intron 7 from the ATG exon, two nucleotides from the previous exon. The Dpyd transcript contains 23 total exons. Multiple transcripts of the Dpyd gene are displayed on Ensembl. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction
The Dpyd gene encodes the 1025 amino acid dihydropyrimidine dehydrogenase (DPD). DPD is involved in pyrimidine base degradation, and catalyzes the reduction of uracil and thymine using NADP+.   The enzyme has three iron-sulfur (4Fe-4S) binding domains at amino acids 69-100, 944-976, and 978-1007 (Uniprot Q8CHR6).
