Epigenetics - Wikipedia
In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi- (ἐπι- "over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of ...

About Epigenetics | Johns Hopkins Institute of Genetic Medicine
Epigenetic changes can cause medical conditions by changing how genes are used and whether they are turned on or off correctly. Two types of epigenetic disorders are imprinting disorders and Mendelian disorders of the epigenetic machinery (MDEMs).
