A genetic mutation is a hardcopy change in one or more parts of that sequence. This could just make you, you. Or it could contribute to a genetic disease. An epigenetic change also changes a gene's DNA — but not at the sequence level.

What is the difference between epigenetics and mutations?

The main difference between DNA sequence mutations and epigenetic modifications is that the DNA sequence mutations result in the changes in the genetic information whereas the epigenetic modifications result in the modifications of gene expression.

Are epigenetics considered mutations?

Epigenetic mutations, defined as aberrant methylation levels that can lead to unusual gene expression, may be involved in cancer development and important for human aging [6, 7].
