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 footprint of epistasis. [PDF]

open access: yesPLoS Computational Biology, 2018
Variation of an inherited trait across a population cannot be explained by additive contributions of relevant genes, due to epigenetic effects and biochemical interactions (epistasis).

Epistasis regulates genetic control of cardiac hypertrophy

open access: yes, 2023
Abstract The combinatorial effect of genetic variants is often assumed to be additive. Although genetic variation can clearly interact non-additively, methods to uncover epistatic relationships remain in their infancy. We develop low-signal signed iterative random forests to elucidate the complex genetic architecture of cardiac hypertrophy.

Epistasis and its contribution to genetic variance components. [PDF]

open access: yesGenetics, 1995
Abstract We present a new parameterization of physiological epistasis that allows the measurement of epistasis separate from its effects on the interaction (epistatic) genetic variance component. Epistasis is the deviation of two-locus genotypic values from the sum of the contributing single-locus genotypic values.

Strong Selection Significantly Increases Epistatic Interactions in the Long-Term Evolution of a Protein

open access: yes, 2016
Epistatic interactions between residues determine a protein's adaptability and shape its evolutionary trajectory. When a protein experiences a changed environment, it is under strong selection to find a peak in the new fitness landscape.

A strategy to apply quantitative epistasis analysis on developmental traits

open access: yesBMC Genetics, 2017
Background Genetic interactions are keys to understand complex traits and evolution. Epistasis analysis is an effective method to map genetic interactions. Large-scale quantitative epistasis analysis has been well established for single cells.

Comparison of the Accuracy of Epistasis and Haplotype Models for Genomic Prediction of Seven Human Phenotypes

open access: yesBiomolecules, 2023
The accuracy of predicting seven human phenotypes of 3657–7564 individuals using global epistasis effects was evaluated and compared to the accuracy of haplotype genomic prediction using 380,705 SNPs and 10-fold cross-validation studies.

The effect of host heterogeneity and parasite intragenomic interactions on parasite population structure [PDF]

open access: yes, 2005
Understanding the processes that shape the genetic structure of parasite populations and the functional consequences of different parasite genotypes is critical for our ability to predict how an infection can spread through a host population and for the ...

Speciation Genetics: Epistasis, Conflict and the Origin of Species [PDF]

open access: yesCurrent Biology, 2007
Evolutionary biologists have long recognized that the sterility and inviability of species hybrids must involve incompatible epistatic interactions between two (or more) genes. The first pair of such hybrid incompatibility genes has now been identified.

Widespread genetic epistasis among cancer genes [PDF]

open access: yesNature Communications, 2014
Quantitative genetic epistasis has been hypothesized to be an important factor in the development and progression of complex diseases. Cancers in particular are driven by the accumulation of mutations that may act epistatically during the course of the disease.
