About SRD5A1

Cytogenetic location: 5p15.31 Genomic coordinates (GRCh38): 5:6,633,440-6,674,386 (from NCBI)

This gene has 4 transcripts (splice variants), 198 orthologues and 3 paralogues. Broad expression in esophagus (RPKM 13.2), skin (RPKM 10.7) and 24 other tissues.

Summary

Steroid 5-alpha-reductase (EC 1.3.99.5) catalyzes the conversion of testosterone into the more potent androgen, dihydrotestosterone (DHT). Also see SRD5A2 (MIM 607306).[supplied by OMIM, Mar 2008]
