Epistasis is when two (or more) different genes contribute to a single phenotype and their effects are not merely additive (deviations from a model of additive multiple effects for quantitative traits). Statistical epistasis Örjan Carlborg and Chris S. Haley, Nature Reviews Genetics, V 5, 2004

Epistasis is an interaction at the phenotypic level of organization. The genes that are involved in a specific epistatic interaction may still show independent assortment at the genotypic level. In

Novel genetic risk markers for ulcerative colitis in the IL2/IL21 region are in epistasis with IL23R and suggest a common genetic background for ulcerative colitis and celiac disease Am J Gastroenterol . Epistasis (Genetics) Please provide your name, email, and your suggestion so that we can begin assessing any terminology changes. Fields denoted with an asterisk (*) are required . The genotype-phenotype maps for these pairs revealed epistasis that cancelled out the additive genetic variance, explaining why these loci were not detected in the additive GWA analysis. Small population sizes, such as in our experiment, increase the risk of identifying false epistatic interactions due to testing for associations with very large numbers of multi-marker genotypes in few Epistasis is when two (or more) different genes contribute to a single phenotype and their effects are not merely additive (deviations from a model of additive multiple effects for quantitative traits). Statistical epistasis Örjan Carlborg and Chris S. Haley, Nature Reviews Genetics, V 5, 2004 Analyzing the evolution of epistasis can also help us understand the forces shaping patterns of genetic architecture.

Epistasis is an interaction at the phenotypic level of organization. The genes that are involved in a specific epistatic interaction may still show independent assortment at the genotypic level. In Dominant epistasis. In some cases, a dominant allele at one locus may mask the phenotype of a second locus.

Epistasis or modifier genes, that is, gene-gene interactions of non-allelic partners, play a major role in susceptibility to common human diseases. This old genetic concept has experienced a major renaissance recently. Interestingly, epistatic genes can make the disease less severe, or make it more severe.

Epistasis is a form on non-Mendelian inheritance in which one gene is capable of interfering with expression of another. This is often found associated with gene pathways where the expression of one gene is directly dependent on the presence or absence of another gene product within the pathway. Watch this video for a quick review of epistasis:

Epistasis has been used to describe a number of phenomena, including the functional interaction between genes, the genetic outcome of mutations acting within the same genetic pathway, and the Epistasis is an important concept in biochemical genetics, population genetics, and quantitative genetics. Although its definition varies somewhat across these fields, the underlying concept is that the effects of allelic substitution at one gene can be dependent on the allelic state of another gene or genes. Epistasis is an interaction at the phenotypic level of organization. The genes that are involved in a specific epistatic interaction may still show independent assortment at the genotypic level. In Dominant epistasis.
