SRD5A2
3-oxo-5α-steroid 4-dehydrogenase 2 is an enzyme that in humans is encoded by the SRD5A2 gene.[5][6] It is one of three forms of 5α-reductase.
Steroid 5α-reductase catalyzes the conversion of the male sex hormone testosterone into the more potent androgen, dihydrotestosterone.
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).[6]
