Gene Prioritization by Integrated Analysis of Protein Structural and Network Topological Properties for the Protein-Protein Interaction Network of Neurological Disorders

الملخص EN

Neurological disorders are known to show similar phenotypic manifestations like anxiety, depression, and cognitive impairment.

There is a need to identify shared genetic markers and molecular pathways in these diseases, which lead to such comorbid conditions.

Our study aims to prioritize novel genetic markers that might increase the susceptibility of patients affected with one neurological disorder to other diseases with similar manifestations.

Identification of pathways involving common candidate markers will help in the development of improved diagnosis and treatments strategies for patients affected with neurological disorders.

This systems biology study for the first time integratively uses 3D-structural protein interface descriptors and network topological properties that characterize proteins in a neurological protein interaction network, to aid the identification of genes that are previously not known to be shared between these diseases.

Results of protein prioritization by machine learning have identified known as well as new genetic markers which might have direct or indirect involvement in several neurological disorders.

Important gene hubs have also been identified that provide an evidence for shared molecular pathways in the neurological disease network.
