Gene Gene information from NCBI Gene database.
Entrez ID 6716
Gene name Steroid 5 alpha-reductase 2
Gene symbol SRD5A2
Synonyms (NCBI Gene)
-
Chromosome 2
Chromosome location 2p23.1
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
