Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Single Nucleotide Polymorphisms-SNPs

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Genetic Screens

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Area of Science:

Genomics
Computational Biology
Bioinformatics

Background:

Disease gene prediction is crucial for reducing experimental costs.
Current methods often rely on static protein-protein interaction (PPI) networks, neglecting network dynamics.
Patient-specific variations in PPIs are not adequately addressed by existing approaches.

Purpose of the Study:

To develop a novel ensemble algorithm for accurate disease gene prediction.
To incorporate dynamic, clinical sample-based networks into disease gene identification.
To overcome limitations of static network models in disease gene prediction.

Main Methods:

Developed EdgCSN, an ensemble algorithm utilizing clinical sample-based networks.
Constructed single sample-based networks and merged them into fused networks.
Employed logistic models with centrality features and an ensemble strategy for prediction.

Main Results:

EdgCSN achieved high AUC values (0.970 for BC, 0.971 for TC, 0.966 for AD).
Demonstrated superior performance compared to competing algorithms in predicting disease-associated genes.
Successfully validated EdgCSN's ability to identify novel disease genes through de novo experiments.

Conclusions:

EdgCSN is an effective ensemble learning algorithm for disease gene prediction.
The algorithm leverages centrality features from clinical sample-based networks.
EdgCSN shows significant promise for identifying new disease-associated genes.
