Gene: SPR
Alternate names for this Gene: SDR38C1
Gene Summary: This gene encodes an aldo-keto reductase that catalyzes the NADPH-dependent reduction of pteridine derivatives and is important in the biosynthesis of tetrahydrobiopterin (BH4). Mutations in this gene result in DOPA-responsive dystonia due to sepiaterin reductase deficiency. A pseudogene has been identified on chromosome 1.
Gene is located in Chromosome: 2
Location in Chromosome : 2p13.2
Description of this Gene: sepiapterin reductase
Type of Gene: protein-coding
