The impact of epistasis in the heterosis and combining ability analyses

open access: yesFrontiers in Plant Science, 2023
The current theoretical knowledge concerning the influence of epistasis on heterosis is based on a simplified multiplicative model. The objective of this study was to assess how epistasis affects the heterosis and combining ability analyses, assuming ...

Physical Constraints on Epistasis [PDF]

open access: yesMolecular Biology and Evolution, 2020
Abstract Living systems evolve one mutation at a time, but a single mutation can alter the effect of subsequent mutations. The underlying mechanistic determinants of such epistasis are unclear. Here, we demonstrate that the physical dynamics of a biological system can generically constrain epistasis.

Multifactorial methods integrating haplotype and epistasis effects for genomic estimation and prediction of quantitative traits

open access: yesFrontiers in Genetics, 2022
The rapid growth in genomic selection data provides unprecedented opportunities to discover and utilize complex genetic effects for improving phenotypes, but the methodology is lacking. Epistasis effects are interaction effects, and haplotype effects may

The genetics of infectious disease susceptibility: has the evidence for epistasis been overestimated? [PDF]

open access: yes, 2013
Interactions amongst genes, known as epistasis, are assumed to make a substantial contribution to the genetic variation in infectious disease susceptibility, but this claim is controversial.

Simulating evolution in asexual populations with epistasis [PDF]

open access: yes, 2021
I show how to use OncoSimulR, software for forward-time genetic simulations, to simulate evolution of asexual populations in the presence of epistatic interactions. This chapter emphasizes the specification of fitness and epistasis, both directly (i.e.,

Evolving concurrent Petri net models of epistasis [PDF]

open access: yes, 2010
A genetic algorithm is used to learn a non-deterministic Petri netbased model of non-linear gene interactions, or statistical epistasis. Petri nets are computational models of concurrent processes.

Epistasis shapes the fitness landscape of an allosteric specificity switch

open access: yesNature 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 ...

Testing for Genetic Interactions in Complex Disease With Distance Correlation. [PDF]

open access: yesBiom J
ABSTRACT Understanding epistasis (genetic interaction) may shed some light on the genomic basis of common diseases, including disorders of maximum interest due to their high socioeconomic burden, like schizophrenia. Distance correlation is an association measure that characterizes general statistical independence between random variables, not only the ...

Whole genome sequencing reveals epistasis effects within RET for Hirschsprung disease

open access: yesScientific 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.
