Evidence-informed definition Updated November 13, 2024 How to cite this entry

Epigenetics is the study of how behaviors and environmental influences can modify gene expression without altering the DNA sequence itself. These epigenetic changes affect how genes are read and can have lasting impacts, sometimes even across generations, by influencing susceptibility to various health conditions and traits.
