About SRD5A2

Cytogenetic location: 2p23.1 Genomic coordinates (GRCh38): 2:31,522,480-31,663,009 (from NCBI)

This gene has 1 transcript (splice variant), 265 orthologues, 3 paralogues and is associated with 3 phenotypes. Biased expression in liver (RPKM 13.3), prostate (RPKM 8.5) and 2 other tissues.

Summary

This gene encodes a microsomal protein expressed at high levels in androgen-sensitive tissues such as the prostate. The encoded protein is active at acidic pH and is sensitive to the 4-azasteroid inhibitor finasteride. Deficiencies in this gene can result in male pseudohermaphroditism, specifically pseudovaginal perineoscrotal hypospadias (PPSH). [provided by RefSeq, Jul 2008]
