Genome-wide epistasis analysis for Alzheimer’s disease and implications for genetic risk prediction
Alzheimer’s Research & Therapy, 2021 Background Single-nucleotide polymorphisms (SNPs) identified by genome-wide association studies only explain part of the heritability of Alzheimer’s disease (AD).

Weak Epistasis Generally Stabilizes Phenotypes in a Mouse Intercross. [PDF]
PLoS Genetics, 2016 The extent and strength of epistasis is commonly unresolved in genetic studies, and observed epistasis is often difficult to interpret in terms of biological consequences or overall genetic architecture. We investigated the prevalence and consequences of

Evolutionary accessibility of mutational pathways [PDF]
, 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 ...

Estimating directional epistasis
Frontiers in Genetics, 2014 Epistasis, i.e. the fact that gene effects depend on the genetic background, is a direct consequence of the complexity of genetic architectures. Despite this, most of the models used in evolutionary and quantitative genetics pay scant attention to ...

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.

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

Genetic Dissection of Cytonuclear Epistasis in Line Crosses [PDF]
Genetics, 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 ...

Pervasive epistasis exposes intramolecular networks in adaptive enzyme evolution
Nature Communications, 2023 Enzyme evolution is characterized by constant alterations of the intramolecular residue networks supporting their functions. The rewiring of these network interactions can give rise to epistasis.

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,

Genetic epistasis regulates amyloid deposition in resilient aging [PDF]
Alzheimer's & Dementia, 2017 AbstractIntroductionThe brain‐derived neurotrophic factor (BDNF) interacts with important genetic Alzheimer's disease (AD) risk factors. Specifically, variants within the SORL1 gene determine BDNF's ability to reduce amyloid β (Aβ) in vitro. We sought to test whether functional BDNF variation interacts with SORL1 genotypes to influence expression and ...
