Non-Syndromic Intellectual Disability and Its Pathways: A Long Noncoding RNA Perspective.

Area of Science:

• Neuroscience
• Genetics
• Molecular Biology

Background:

• Non-syndromic intellectual disability (NS-ID) is a significant global health concern.
• The etiology of NS-ID remains poorly understood due to its complex and heterogeneous nature.
• Long noncoding RNAs (lncRNAs) are increasingly recognized for their roles in neurodevelopmental processes.

Purpose of the Study:

• To synthesize current literature on lncRNAs implicated in intellectual disability.
• To elucidate the involvement of lncRNAs in molecular and cellular pathways relevant to NS-ID.
• To enhance understanding of the regulatory complexity underlying NS-ID.

Main Methods:

• Literature review synthesizing existing research on lncRNAs and intellectual disability.
• Analysis of lncRNA involvement in established neural function and molecular pathways.
• Integration of findings to connect lncRNA functions with NS-ID pathogenesis.

Main Results:

• lncRNAs are implicated in various neurodevelopmental processes crucial for cognitive function.
• Specific lncRNAs may play regulatory roles in pathways associated with intellectual disability.
• The heterogeneity of NS-ID might be partly explained by diverse lncRNA functions and interactions.

Conclusions:

• lncRNAs represent a promising area for understanding the molecular basis of NS-ID.
• Further research into lncRNA mechanisms can provide novel insights into NS-ID etiology.
• Targeting lncRNAs could offer potential therapeutic avenues for NS-ID.
