Gene Gene information from NCBI Gene database.
Entrez ID 6697
Gene name Sepiapterin reductase
Gene symbol SPR
Synonyms (NCBI Gene)
SDR38C1
Chromosome 2
Chromosome location 2p13.2
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 r
