Presynaptic dysfunction in neurodevelopmental disorders: Insights from the synaptic vesicle life cycle

Area of Science:

• Neuroscience
• Genetics
• Developmental Biology

Background:

• Synaptic vesicle (SV) activity is vital for neurotransmission.
• Mutations in essential SV genes were thought to be lethal.
• Increasing evidence links SV gene mutations to neurodevelopmental disorders (NDDs).

Purpose of the Study:

• To review the link between presynaptic gene mutations and NDDs.
• To explore how SV life cycle disruptions cause human disease.
• To discuss future therapeutic strategies targeting presynaptic function.

Main Methods:

• Literature review of presynaptic genes and NDDs.
• Sequential analysis of the synaptic vesicle life cycle.
• Discussion of disease mechanisms and therapeutic targets.

Main Results:

• Identification of numerous mutations in SV genes associated with NDDs.
• Correlation between specific SV recycling defects and distinct NDD phenotypes.
• Emerging understanding of how SV dysfunction impacts neuronal communication.

Conclusions:

• Presynaptic gene mutations are a significant factor in NDDs.
• The SV life cycle provides a framework for understanding these disorders.
• Targeting presynaptic function holds therapeutic promise for NDDs.
