Genome-wide Association Studies-GWAS

15.2K
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...

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

DNA Microarrays

20.5K
Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...

Evolutionary Relationships through Genome Comparisons

6.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Polygenic Traits01:18

Polygenic Traits

68.8K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Area of Science:

  • Genetics
  • Statistical genetics
  • Bioinformatics

Background:

  • Single-locus association mapping methods are widely used but can be limited in power and prone to multiple testing issues.
  • There is a need for more powerful and interpretable methods for multi-locus association mapping.

Purpose of the Study:

  • To introduce Eagle, a novel method designed for straightforward and effective multi-locus association mapping.
  • To demonstrate Eagle's advantages over existing single- and multi-locus approaches.

Main Methods:

  • Eagle employs a multi-locus association mapping strategy.
  • The method's performance was evaluated through extensive simulations and analysis of a published mouse dataset.

Main Results:

  • Eagle significantly outperforms competing single- and multi-locus methods in identifying true single-nucleotide polymorphism (SNP) trait associations and avoiding false positives.
  • In a mouse study analysis, Eagle identified over 50% more validated findings compared to the leading single-locus method.

Conclusions:

  • Eagle offers a powerful, interpretable, and computationally efficient alternative for multi-locus association mapping.
  • The method is readily accessible as an R package with a user-friendly graphical interface.
