Two-stage genome-wide search for epistasis with implementation to Recombinant Inbred Lines (RIL) populations. [PDF]

PLoS ONE, 2014
OBJECTIVE AND METHODS:This paper proposes an inegrative two-stage genome-wide search for pairwise epistasis on expression quantitative trait loci (eQTL).

Dynamic network-based epistasis analysis: Boolean examples

Frontiers in Plant Science, 2011
In this review we focus on how the hierarchical and single-path assumptions of epistasis analysis can bias the topologies of gene interactions infered. This has been acknowledged in several previous papers and reviews, but here we emphasize the critical ...

Parallel and serial computing tools for testing single-locus and epistatic SNP effects of quantitative traits in genome-wide association studies

BMC Bioinformatics, 2008
Background Genome-wide association studies (GWAS) using single nucleotide polymorphism (SNP) markers provide opportunities to detect epistatic SNPs associated with quantitative traits and to detect the exact mode of an epistasis effect.

Clinical Implications of Digenic Inheritance and Epistasis in Primary Immunodeficiency Disorders

Frontiers in Immunology, 2018
The existence of epistasis in humans was first predicted by Bateson in 1909. Epistasis describes the non-linear, synergistic interaction of two or more genetic loci, which can substantially modify disease severity or result in entirely new phenotypes ...

Epistasis in Monkeyflowers [PDF]

Genetics, 2005
AbstractEpistasis contributes significantly to intrapopulation variation in floral morphology, development time, and male fitness components of Mimulus guttatus. This is demonstrated with a replicated line-cross experiment involving slightly over 7000 plants. The line-cross methodology is based on estimates for means. It thus has greater power than the

Epistasis Storyboarded

The American Biology Teacher, 2022
Through the artistic planning tool known to comic book artists and animators as storyboarding, students will embark on comic book–style adventures to plan, describe, and visualize the complex life of genes through the non-Mendelian concept of epistasis.

Mechanistic causes of sign epistasis and its applications

Frontiers in Genetics
Mapping genetic variations to phenotypic variations poses a significant challenge, as mutations often combine unexpectedly, diverging from assumed additive effects even in the same environment.

Towards a Better Basis Search through a Surrogate Model-Based Epistasis Minimization for Pseudo-Boolean Optimization

Mathematics, 2020
Epistasis, which indicates the difficulty of a problem, can be used to evaluate the basis of the space in which the problem lies. However, calculating epistasis may be challenging as it requires all solutions to be searched.

Epistasis: obstacle or advantage for mapping complex traits? [PDF]

PLoS ONE, 2010
Identification of genetic loci in complex traits has focused largely on one-dimensional genome scans to search for associations between single markers and the phenotype.

A general model for multilocus epistatic interactions in case-control studies. [PDF]

PLoS ONE, 2010
BACKGROUND: Epistasis, i.e., the interaction of alleles at different loci, is thought to play a central role in the formation and progression of complex diseases.
