About QDPR

Cytogenetic location: 4p15.32 Genomic coordinates (GRCh38): 4:17,486,395-17,512,090 (from NCBI)

This gene has 9 transcripts (splice variants), 236 orthologues and is associated with 3 phenotypes. Broad expression in brain (RPKM 86.6), kidney (RPKM 64.2) and 24 other tissues.

Summary

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]
