Area of Science:

  • Neuroscience
  • Epigenetics
  • Developmental Biology

Background:

  • Genetic studies have advanced neurodevelopmental disorder diagnosis and treatment.
  • Epigenetic mechanisms, particularly Polycomb Repressive Complex 2 (PRC2), are vital for generating neuronal diversity in the human brain.

Purpose of the Study:

  • To review foundational knowledge on PRC2's role in epigenetic transcriptional silencing.
  • To highlight recent findings on PRC2 subcomplex evolution, neurodevelopmental functions, and links to human developmental disorders.

Main Methods:

  • Literature review of foundational and recent studies on PRC2.
  • Analysis of evolutionary complexity of PRC2 subcomplexes.
  • Examination of PRC2's role in neurodevelopment and associated disorders.

Main Results:

  • PRC2 is a key epigenetic regulator maintaining transcriptional silencing.
  • PRC2 subcomplexes show increasing evolutionary complexity.
  • PRC2 plays significant roles in human neurodevelopment and is implicated in developmental disorders.

Conclusions:

  • PRC2 is essential for neuronal diversity and proper nervous system development.
  • Understanding PRC2's complex roles and evolutionary trajectory is critical for addressing neurodevelopmental disorders.
