title: [Genetics and epigenetics. Explanatory approaches for (gender-specific) mechanisms of disease development].
abstract: Whereas the central role of DNA as the carrier of genetic information has long been well known, the impact of epigenetic mechanisms as mediators between genes and environment is now becoming increasingly clear. Epigenetics helps explain the partially reversible interplay between gene function and environment and even permits observation of the transgenerational transmission of epigenetic modifications. Of special interest are gender-specific mechanisms of gene regulation which, among others, offer an explanation for gender differences in human diseases. Since the study of epigenetic mechanisms and their impact on the etiology of common diseases is in its infancy, it is too early to draw general conclusions from the current state of knowledge. Moreover, completely new strategies are needed to research these effects. In addition to molecular findings, definitions of specific phenotypes are required, including biographic data of affected individuals and their ancestors. Epigenetics needs to be viewed in the context of the theory of evolution, classical genetics, and environmental research. Its aim is not to substitute the knowledge in these disciplines, but rather to provide a key to link their findings, thereby opening up new possibilities in terms of interpretation and understanding of gender differences in medicine. If these epigenetic mechanisms are better understood, particularly in terms of specific diseases, it is conceivable that these disorders could be influenced and treated in a more targeted manner in the future.
