An update on autophagy disorders.

Area of Science:

• Cell Biology
• Genetics
• Clinical Medicine

Background:

• Macroautophagy is crucial for cellular homeostasis, especially in post-mitotic tissues.
• Defects in autophagy genes lead to congenital disorders with shared clinical features like neurodevelopmental and neurodegenerative issues.
• Vici syndrome, caused by EPG5 gene defects, is a key example of a congenital autophagy disorder.

Purpose of the Study:

• To review autophagy in relation to intracellular trafficking.
• To describe congenital autophagy disorders, their clinical signatures, and recommended health surveillance.
• To discuss recent molecular mechanisms and future therapeutic strategies.

Main Methods:

• Literature review of autophagy pathways and associated genetic disorders.
• Analysis of clinical and genetic data from identified autophagy-related diseases.
• Synthesis of current research on pathophysiology and therapeutic development.

Main Results:

• Identification of numerous autophagy-associated disease genes beyond core machinery.
• Expansion of the spectrum of congenital autophagy disorders linking selective autophagy and vesicular trafficking.
• Enhanced understanding of pathophysiology providing a basis for therapy development.

Conclusions:

• Congenital disorders of autophagy represent a significant clinical and molecular spectrum.
• Advances in basic research are crucial for understanding disease mechanisms and developing therapies.
• Primary health surveillance protocols are essential for managing these rare genetic conditions.
