5αR2 is expressed in specific tissues and catalyzes the transformation of testosterone (T) to 5α-dihydrotestosterone (DHT). DHT plays a key role in the process of sexual differentiation in the external genitalia and prostate during the development of the male fetus. 5αR2D is a result of impaired 5αR2 activity resulting in decreased DHT levels.
