Epigenetics Explained | Penn Medicine

What are epigenetics, and how could they change the face of medicine? Penn Medicine is here to explain.

Until recently, scientists believed that gene mutations were the only source of human diseases – but it turns out to be more complicated. Enter: Epigenetics, a rapidly expanding field of science that can help to explain some of the perplexing biomedical questions that simple Mendelian genetics cannot.

Epigenetics is a layer of regulation over our genes that is key to how genes are turned on and off.
