The Potential Role of miRNAs as Predictive Biomarkers in Neurodevelopmental Disorders

Area of Science:

• Neuroscience
• Molecular Biology
• Genetics

Background:

• Neurodevelopmental disorders (NDDs) manifest early in childhood with cognitive, behavioral, and functional deficits.
• Examples include autism spectrum disorder, ADHD, and Down syndrome, affecting millions globally.
• Current understanding of NDD molecular mechanisms is limited, hindering early diagnosis and effective treatment.

Purpose of the Study:

• To review the current understanding of microRNA roles in neurodevelopmental disorders.
• To explore the potential of microRNAs as diagnostic biomarkers for NDDs.
• To highlight the need for improved diagnostic tools for better patient prognosis.

Main Methods:

• Literature review focusing on microRNA regulation in central nervous system development.
• Analysis of studies linking altered microRNA expression to NDDs.
• Synthesis of current knowledge on microRNAs in neurodevelopment.

Main Results:

• MicroRNAs (miRNAs) are small non-coding RNAs involved in gene regulation.
• Altered miRNA expression patterns are observed in various neurodevelopmental disorders.
• miRNAs play a crucial role in neurodevelopmental processes and their dysregulation contributes to NDDs.

Conclusions:

• MicroRNAs represent a promising avenue for developing novel diagnostic biomarkers for NDDs.
• Early detection through miRNA biomarkers could significantly improve patient outcomes and quality of life.
• Further research into miRNA function and regulation is essential for clinical applications in NDDs.
