17-beta-hydroxysteroid dehydrogenase deficiency-3 is biochemically characterized by decreased levels of testosterone and increased levels of androstenedione as a result of the defect in conversion of androstenedione into testosterone. This leads to clinically important higher ratio of androstenedione to testosterone (A'dion/T) (see figure).

Overview

17-beta-hydroxysteroid dehydrogenase deficiency-3 is biochemically characterized by decreased levels of testosterone and increased levels of androstenedione as a result of the defect in conversion of androstenedione into testosterone.

Pathophysiology

Biochemical effects of 17β-hydroxysteroid deficiency-3 in testosterone biosynthesis. Typically levels of androstenedione are significantly increased, whilst testosterone levels are decreased, leading to male undervirilization.

Genetics

17-beta-hydroxysteroid dehydrogenase deficiency-3 is caused by gene mutations found in the 17BHSD3 gene. 17-beta-hydroxysteroid dehydrogenase deficiency-3 is an autosomal recessive disorder.
