Summary
MecCog is a graphical framework for integrating genetic disease mechanisms. This tool aids in identifying biomarkers and therapeutic targets by visualizing disease pathways.
Area of Science:
- Genetics
- Bioinformatics
- Systems Biology
Background:
- Genetic disease mechanisms are fragmented across scientific literature.
- Current representations (text, diagrams) hinder integration and utility.
Purpose of the Study:
- To present MecCog, a graphical framework for constructing integrated representations of genetic disease mechanisms.
- To facilitate the organization and visualization of how genetic variants lead to disease phenotypes.
Main Methods:
- Developed MecCog, a web platform for creating 'mechanism schemas'.
- Schemas depict perturbation propagation across biological organization levels.
- Utilizes graphical notations, hyperlinked evidence, ontology, and uncertainty depiction.
Main Results:
- MecCog enables users to build, store, publish, and query mechanism schemas.
- Schemas visualize disease mechanisms, aiding in identifying biomarkers and therapeutic targets.
- Facilitates the identification of critical future experiments.
Conclusions:
- MecCog provides a structured approach to representing complex genetic disease mechanisms.
- The framework enhances the utility of experimental findings for research and therapeutic development.

Epistasis Analysis
5.4K
Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. Epistasis often involves one gene masking or interfering with the expression of another (antagonistic epistasis). Epistasis often occurs when different genes are part of the same biochemical pathway. The...

Incomplete Dominance
28.3K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Genetic Screens
5.3K
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.

Genomics
38.3K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Genome-wide Association Studies-GWAS
14.8K
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.
