SPR - sepiapterin reductase Gene

Homo sapiens

Also known as SDR38C1

Gene ID: 6697 | Gene type: protein coding

About SPR

Cytogenetic location: 2p13.2 Genomic coordinates (GRCh38): 2:72,887,408-72,892,158 (from NCBI)

This gene has 2 transcripts (splice variants), 240 orthologues and is associated with 3 phenotypes. Ubiquitous expression in kidney (RPKM 23.8), colon (RPKM 21.8) and 24 other tissues.

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. [provided by RefSeq, Jul 2008]
