Epigenetics has been defined as the study of stable alterations in gene expression potentials that arise during development and cell proliferation, or alterations in DNA function without alterations in DNA sequence. Modern epigenetic features refer to the alteration of DNA and/or associated proteins without nucleotide sequence variance, which transmits the data contained to the next generation. It has been considered that diseases are generally influenced by obtained biological alterations, but it is becoming evident that any phenotype is the result of a complex interplay between genotype, epigenome, and environment. Epigenetics concentrates on pathways that control how and when specific genes are turned on and/or off, while epi-genomics assess epigenetic changes in a cell or whole organism across many genes.
