Disease classification via gene network integrating modules and pathways.

Area of Science:

• Genomics
• Systems Biology
• Computational Biology

Background:

• Disease classification is crucial for precision medicine.
• Existing methods often rely on gene expression data and disease gene overlaps.
• A deeper understanding of disease mechanisms at the network level is needed.

Purpose of the Study:

• To develop a novel disease classification model using gene network modules and pathways.
• To define disease distances based on their effects on biological functions.
• To explore new avenues for understanding disease etiology and pathology.

Main Methods:

• Assessed disease impact on human biological functions via gene network modules and pathways.
• Defined distances between diseases based on pathway effects.
• Developed classification models using these defined distances.
• Classified 1728 diseases into 12 and 14 categories based on pathway intensity and scope.

Main Results:

• Successfully classified 1728 diseases into distinct categories based on gene network analysis.
• Identified categories that integrate diseases with diverse origins (congenital, acquired) and affected tissues.
• Demonstrated that gene network-based classification complements traditional pathology.

Conclusions:

• Gene network analysis provides a new perspective on disease classification, focusing on common etiological and pathological factors.
• This approach supports the exploration of combination therapies.
• The findings lay the groundwork for advanced gene-targeted therapeutic strategies.
