MaxLink

MaxLink identifies and ranks genes closely associated with a user-provided query gene list using a guilt-by-association approach within protein interaction networks to predict potential disease-related genes.

Key Features:

• Guilt-by-association analysis: Infers candidate genes based on association patterns with query genes within protein interaction networks.
• Underlying network: Uses FunCoup 3.0 as the protein interaction network foundation for linkage and association data.
• Gene ranking by connectivity: Produces ranked lists of genes by their connectivity to known disease-associated or query genes.
• Updated algorithm: Incorporates an updated algorithm intended to enhance prediction of potential disease-related genes.
• Statistically robust candidate selection: Adopts a more statistically robust method for selecting candidate genes.
• C++ implementation and performance: Algorithm re-implemented in C++ to improve computational efficiency and speed, facilitating large-scale network analyses.

Scientific Applications:

• Disease gene discovery: Prioritizes candidate genes connected to known disease genes to support identification of novel gene-disease associations.
• Cancer research: Applies guilt-by-association ranking to gene lists in oncology-focused studies.
• General network biology: Enables exploration of gene connections across diverse biological contexts beyond oncology.

Methodology:

Uses a guilt-by-association approach within protein interaction networks (FunCoup 3.0); applies an updated algorithm with a statistically robust method for selecting candidate genes; ranks genes by connectivity to known disease-associated genes; implementation re-implemented in C++ for improved efficiency.
