Epigenetics, a relatively new field in science, could help define the causes of Autism and offer up new modes of treatment for the disorder, as well as other diseases like cancer, schizophrenia, Alzheimer’s and diabetes. Epigenetics is the study of gene expression governed by the epigenome, the cellular material that sits on top of our genetic code.
The epigenome does not change the genetic code inscribed in our DNA; rather, it activates or silences genes through the mobilization of molecules called methyl groups. These chemical changes are triggered by our environment. Toxins, pollutants, changes in diet, deficiencies in prenatal nutrition, and exposure to stressors alters the way our genes are expressed through the epigenome.Furthermore, epigenetics has proven that these changes in gene expression are passed down to our offspring, for at least one generation. Epigenetics renders the argument of nature vs. nuture moot because it establishes that the two are are inextricably intertwined. In regards to human development, one is as important as the other.
We can use epigenetic inheritance to restore the action of our genetic code from one generation to the next. Once environmental stressors are removed and behavior is corrected, our DNA will revert to its original programming. We could cure diabetes through behavioral changes that allow our epigenome to operate correctly. The elimination of toxins and pollutants could greatly reduce the incidence of cancer and birth defects. Such modification of environmental exposures and behaviors will restore and even improve the overall health and capacity of our genetic line.
