Twin pairs with significant differences in DNA methylation and histone acetylation profiles: Estrogen and its receptors play an important role in breast carcinogenesis. There are several possible explanations for these observations, but one is the existence of epigenetic differences. Epigenetics Study of mitotically heritable alterations in gene expression potential that are not mediated.
User comments must be in English, comprehensible and relevant to lifegime article under discussion. These findings indicate how an appreciation of epigenetics is missing from our understanding of how different phenotypes can be originated from the same genotype.

However, most monozygotic twin pairs are not identical; several types of phenotypic discordance may be observed, such as differences in susceptibilities to disease and a wide range of anthropomorphic features. You work at the same institute as any of the authors. We found that, although twins are epigenetically indistinguishable during the early years of life, older monozygous twins exhibited remarkable differences in their overall content furing genomic distribution of 5-methylcytosine DNA and histone acetylation, affecting their gene-expression portrait.
