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...

Combinatorial Gene Control

Combinatorial Gene Control

Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

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...

Genome Size and the Evolution of New Genes

Genome Size and the Evolution of New Genes

While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Area of Science:

Data Mining
Artificial Intelligence
Machine Learning

Background:

Real-world data often contains contextual information crucial for interpreting features and patterns.
Discovering context-sensitive patterns is vital for deriving accurate meaning from complex datasets.
Existing methods may not adequately capture the nuances of context-dependent associations.

Purpose of the Study:

To formulate and address the problem of mining context-aware association rules.
To develop a methodology for discovering associations where implication strength is context-dependent.
To integrate user's background knowledge into the pattern discovery process.

Main Methods:

A grammar-based genetic programming methodology is proposed to mine context-aware association rules.
This approach restricts the search space and incorporates syntax constraints.
Grammars serve as a mechanism for introducing subjective or domain-specific knowledge.

Main Results:

The proposed approach was evaluated using synthetically generated datasets.
Experiments demonstrated the feasibility and effectiveness of the methodology.
The approach successfully identified interesting context-aware associations in real-world datasets.

Conclusions:

The developed method is effective for discovering context-aware association rules.
This approach offers a valuable tool for analyzing complex, context-dependent data.
Applications in domains like education can yield insights into student behavior and performance.
