Distal inhibitors of cholesterol synthesis cause holoprosencephalies. This is linked to Smith-Lemli-Opitz syndrome and Sonic Hedgehog gene function in brain development.

Area of Science:

  • Developmental biology
  • Biochemistry
  • Teratology

Context:

  • Teratogenic effects of distal cholesterol synthesis inhibitors are known.
  • Holoprosencephalies are a specific type of malformation induced by these inhibitors.
  • Recent interest stems from Smith-Lemli-Opitz syndrome and Sonic Hedgehog (Shh) gene involvement.

Purpose:

  • To explore the link between cholesterol synthesis inhibition and holoprosencephalies.
  • To connect teratogenic mechanisms with human genetic disorders.
  • To understand the role of Shh protein in prosencephalon development.

Summary:

  • Distal cholesterol synthesis inhibitors induce holoprosencephalies, a specific developmental defect.
  • The discovery of Smith-Lemli-Opitz syndrome (SLOS) in 1993, a human disorder linked to cholesterol synthesis defects, has renewed interest.

Related Experiment Videos

  • The Sonic Hedgehog (Shh) gene's role in prosencephalon development and Shh protein's "cholesterolisation" process are also key factors.

    • Impact:

    • Provides insights into the etiology of holoprosencephalies.
    • Highlights the critical role of cholesterol in embryonic development.
    • Suggests potential therapeutic targets for developmental disorders.
