Any time two different genes contribute to a single phenotype and their effects are not merely additive, those genes are said to be epistatic. Epistasis is an interaction at the phenotypic level ...

Did you know that genes can mask and alter the effects of other genes? Could this process, called epistasis, be a key to understanding complex conditions like Alzheimer’s disease and diabetes?

They've also unearthed 95 new gene interactions that could influence the effects of variants in Alzheimer's. The team has ...
