Gap junctions, formed by connexins, are vital for cellular communication and tissue homeostasis. Mutations in connexin genes are increasingly linked to various human hereditary diseases, impacting multiple organ systems.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Genetics

Context:

  • Gap junctions facilitate intercellular communication by forming direct channels between cells.
  • Connexins are the protein components of gap junctions, crucial for cellular homeostasis.
  • Transgenic mouse models have elucidated the diverse roles of connexins in cellular functions.

Purpose:

  • To review the current understanding of connexin involvement in human pathologies.
  • To highlight the link between connexin gene mutations and hereditary diseases.
  • To provide a comprehensive overview of connexin-related human diseases.

Summary:

  • Gap junctions are essential for maintaining tissue homeostasis through direct cell-to-cell communication.
  • Connexin gene mutations are associated with a growing list of hereditary conditions.
