Partial 3 beta-hydroxysteroid dehydrogenase deficiency presents in classical and late-onset forms. Diagnosis involves specific steroid ratios, with treatment focusing on glucocorticoids and cyproterone acetate.

Area of Science:

  • Endocrinology
  • Steroidogenesis
  • Genetics

Context:

  • Partial 3 beta-hydroxysteroid dehydrogenase (3β-HSD) deficiency affects adrenal and gonadal steroid production.
  • Recognized forms include classical (salt-losing, ambiguous genitalia) and late-onset (hyperandrogenism, oligomenorrhea).
  • This autosomal recessive condition impacts both adrenal and gonadal tissues.

Purpose:

  • To provide an overview of partial 3 beta-hydroxysteroid dehydrogenase deficiency.
  • To highlight diagnostic criteria and therapeutic strategies.
  • To discuss the association with polycystic ovary syndrome.

Summary:

  • Classical 3β-HSD deficiency causes salt-losing syndrome or ambiguous genitalia.
  • Late-onset forms are increasingly diagnosed in patients with hyperandrogenism and/or oligomenorrhea.

  • Diagnostic confirmation relies on elevated delta 5/delta 4 steroid ratios, specifically 17-hydroxypregnenolone/17-hydroxyprogesterone.

    • Impact:

    • Glucocorticoid therapy can restore menses and ovulation.
    • Cyproterone acetate effectively manages cutaneous hyperandrogenism symptoms.
    • Understanding this deficiency is crucial for diagnosing and managing reproductive and adrenal disorders.
