For many of us ‘epigenetics’ is not a familiar word, and least of all, that it has something to do with autism.  But the fact of the matter is that it has everything to do with autism.  In 1940, the British embryologist and geneticist Conrad Waddington was the first to coin the term epigenetics and he described it as «the interactions of genes with their environment, which bring the phenotype into being.»  Today, however, researchers are taking epigenetics one step further and looking at how the DNA methylation is being altered.

Basically, toxic environmental exposures can cause abnormal gene expression which is what we are now seeing with the widespread genetic mutation called the Methylenetetrahydrofolate Reductase (MTHFR).  According to the study on the «Association of MTHFR Gene Variants with Autism«, 98% of children with autism carry at least one copy of the MTHFR.  This means there is a defect in the methylation process which ultimately affects the body’s ability to excrete toxins effectively.  See the Methylation/MTHFR section of The Autism Exchange.  The bottom line is environmental factors can trigger changes in our DNA by turning our genes on and off.

Tom Insel MD, Director of the National Institute of Mental Health (NIMH) in his blog «The New Genetics of Autism –Why Environment Matters» states that: «Increasing [autism] prevalence suggests environmental factors like chemicals and microbes changing over the past decade, whereas genes change over generations.  Why is anyone looking for genetic causes when there is such a rapid increase in [autism] prevalence?  Shouldn’t every research dollar be invested in finding the environmental culprit rather than searching for rare gene variants?»

Historically, we have seen that any organism – plant, animal, or human – has somehow found the ability to adapt to various environmental factors in order to survive.  So it should be of no surprise that today adaptation and survival is what humans and their DNA are doing now.  Time Magazine even published an article called «Why Your DNA Is Not Your Destiny» by John Cloud.  Epigenetics not only affects autism, but also affects so many other medical conditions that are on the rise.  We all have to learn how to adapt in order to survive in this toxic world in which we live.

Epigenetic Theory of Autism: Autism Tornado in the Brain
Description:   “It’s becoming quite clear to more and more of us that autism is not genetic, but epigenetic.” So says William J. Walsh, who received a Ph.D. in chemical engineering from Iowa State University and is an expert in nutritional medicine. In the 1970s, he collaborated with the renowned Dr. Carl Pfeiffer, a pioneer in schizophrenia research, and went on to develop nutrient protocols to normalize brain chemistry in patients with behavioral and personality disorders, schizophrenia, and autism.
