Epistasis shapes the fitness landscape of an allosteric specificity switch
Nature Communications, 2021 Epistasis plays an important role in the evolution of novel protein functions because it determines the mutational path a protein takes. Here, the authors combine functional, structural and biophysical analyses to characterize epistasis in a ...

Hidden epistastic interactions can favour the evolution of sex and recombination. [PDF]
PLoS ONE, 2012 Deleterious mutations can have a strong influence on the outcome of evolution. The nature of this influence depends on how mutations combine together to affect fitness.

Whole genome sequencing reveals epistasis effects within RET for Hirschsprung disease
Scientific Reports, 2022 Common variants in RET and NRG1 have been associated with Hirschsprung disease (HSCR), a congenital disorder characterised by incomplete innervation of distal gut, in East Asian (EA) populations.

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

Detecting epistasis via Markov bases [PDF]
, 2010 Rapid research progress in genotyping techniques have allowed large genome-wide association studies. Existing methods often focus on determining associations between single loci and a specific phenotype.

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.

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 ...

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 not needed to explain low dN/dS
, 2012 An important question in molecular evolution is whether an amino acid that occurs at a given position makes an independent contribution to fitness, or whether its effect depends on the state of other loci in the organism's genome, a phenomenon known as ...

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.
