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

open access: yesPLoS 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.

Competition between recombination and epistasis can cause a transition from allele to genotype selection [PDF]

open access: yes, 2009
Biochemical and regulatory interactions central to biological networks are expected to cause extensive genetic interactions or epistasis affecting the heritability of complex traits and the distribution of genotypes in populations. However, the inference

Maternal-Zygotic Epistasis and the Evolution of Genetic Diseases [PDF]

open access: yesJournal of Biomedicine and Biotechnology, 2010
Many birth defects and genetic diseases are expressed in individuals that do not carry the disease causing alleles. Genetic diseases observed in offspring can be caused by gene expression in mothers and by interactions between gene expression in mothers and offspring.

Idiosyncratic and dose-dependent epistasis drives variation in tomato fruit size

open access: yesScience, 2023
Epistasis between genes is traditionally studied with mutations that eliminate protein activity, but most natural genetic variation is in cis-regulatory DNA and influences gene expression and function quantitatively.

Genetic epistasis in female suicide attempters

open access: yesProgress in Neuro-Psychopharmacology and Biological Psychiatry, 2012
Complex behaviors such as suicidal behavior likely exhibit gene-gene interactions. The main aim of this study is to explore potential single nucleotide polymorphisms combinations with epistatic effect in suicidal behavior using a data mining tool (Multifactor Dimensionality Reduction).Genomic DNA from peripheral blood samples was analyzed using SNPlex ...

Genetic Dissection of Cytonuclear Epistasis in Line Crosses [PDF]

open access: yesGenetics, 2007
Abstract Dissection of cytonuclear interactions is fundamentally important for understanding the genetic architecture of complex traits. Here we propose a mating design based on reciprocal crosses and extend the existing QTL mapping method to evaluate the contribution of cytoplasm and QTL × cytoplasm interactions to the phenotypic ...

Stability-mediated epistasis constrains the evolution of an influenza protein. [PDF]

open access: yes, 2013
John Maynard Smith compared protein evolution to the game where one word is converted into another a single letter at a time, with the constraint that all intermediates are words: WORD→WORE→GORE→GONE→GENE. In this analogy, epistasis constrains evolution,

Evolutionary accessibility of mutational pathways [PDF]

open access: yes, 2011
Functional effects of different mutations are known to combine to the total effect in highly nontrivial ways. For the trait under evolutionary selection (`fitness'), measured values over all possible combinations of a set of mutations yield a fitness ...

Functional Regression Models for Epistasis Analysis of Multiple Quantitative Traits.

open access: yesPLoS Genetics, 2016
To date, most genetic analyses of phenotypes have focused on analyzing single traits or analyzing each phenotype independently. However, joint epistasis analysis of multiple complementary traits will increase statistical power and improve our ...

Influence of epistasis on response to genomic selection using complete sequence data

open access: yesGenetics Selection Evolution, 2017
Background The effect of epistasis on response to selection is a highly debated topic. Here, we investigated the impact of epistasis on response to sequence-based selection via genomic best linear prediction (GBLUP) in a regime of strong non-symmetrical ...
