Shared Immune and Nutrient Metabolism Pathways Between Autism Spectrum Disorder and Celiac Disease: An In Silico...

Area of Science:

• Neuroscience
• Immunology
• Genetics

Background:

• Autism spectrum disorder (ASD) is a neurodevelopmental condition with social communication challenges.
• Celiac disease (CD) is an autoimmune disorder triggered by gluten.
• Emerging research suggests a potential link between ASD and CD, possibly due to immune and nutritional factors.

Purpose of the Study:

• To investigate shared biological pathways between ASD and CD using an in silico approach.
• To identify potential mechanistic links connecting these two conditions.

Main Methods:

• Gene-disease associations for ASD and CD were retrieved from DisGeNET.
• Over-representation analysis (ORA) was performed using GeneTrail 3.2 to identify enriched pathways.
• Statistical significance was determined using a false discovery rate (FDR) < 0.05.

Main Results:

• 536 ASD-related genes and 52 CD-related genes were identified.
• Shared biological pathways included immune function, cellular metabolism, and micronutrient processing (folate, selenium, vitamin A).
• Findings indicate immune dysfunction and nutrient malabsorption as potential links between ASD and CD.

Conclusions:

• Pathway overlap supports immune dysregulation and metabolic disturbances in both ASD and CD.
• Nutrient deficiencies from CD may exacerbate ASD symptoms.
• Future research should focus on clinical validation and dietary interventions for individuals with both conditions.
