MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the enzyme dihydropteridine reductase, which catalyzes the NADH-mediated reduction of quinonoid dihydrobiopterin. This enzyme is an essential component of the pterin-dependent aromatic amino acid hydroxylating systems. Mutations in this gene resulting in QDPR deficiency include aberrant splicing, amino acid substitutions, insertions, or premature terminations. Dihydropteridine reductase deficiency presents as atypical phenylketonuria due to insufficient production of biopterin, a cofactor for phenylalanine hydroxylase. [provided by RefSeq, Jul 2008]
PHENOTYPE: A portion of mice homozygous for a knock-out allele display abnormal rib-sternum attachment, a split xiphoid process, and lumbar vertebral transformation. Another knock-out allele exhibits abnormal folate and biopterin metabolism and oxidative stress in the liver. [provided by MGI curators]
