How long are we going to listen to experts blaming bad genes for autism? This is 52 percent of autism. What’s the rest? ….Fat moms, old moms, old dads, drinking moms, smoking moms, moms who have babies too close together, moms who live too close to freeways…..
Genetics plays more of a role in the development of autism than environmental causes, according to new research published Sunday in Nature Genetics….
“There is no one gene for autism,” Gunter said. “Instead there are many different genetic variations which each contribute a little bit to the risk of developing the group of symptoms we diagnose as autism.”
She added that we still don’t know exactly how much these different factors contribute to the development of autism.
Once scientists accumulate more data on the autism population, Buxbaum says this new research could help develop a “risk score” – such as the one that exists for heart attacks – that would help patients determine the likelihood of family members developing autism.
Jeffrey Kluger at TIME and Steven Salzberg at Forbes have both slammed Robert Kennedy’s new book on thimerosal use in vaccines.
Stories on the latest study showing autism is “mostly genetic,” and therefore not linked to vaccines are filling up Google News.
What we have is a serious lack of trust in one of the most important programs in pediatric medicine: the vaccine schedule. This heated debate is escalating to the point where we need answers: either vaccines do or vaccines don’t cause autism. Sharyl is right. A simple study comparing the autism rate in children who are fully vaccinated and children who have never been vaccinated would end the controversy. We’d be able to see for ourselves. (And the CDC does retrospective studies like this all the time. With so many parents now too worried to vaccinate, the study group is out there.) UNLESS AND UNTIL THIS STUDY IS DONE, THE QUESTION REMAINS OPEN.
The obvious difference is there are many scientific studies supporting a link between vaccines and autism–often unreported, under-reported or dismissed by pharmaceutical interests and vaccine activists who have long fought a PR campaign to falsely portray the studies and researchers as “anti-vaccine.”
I told the CDC official that it would seem that a survey of the unvaccinated population could be a good first step in further dispelling or further confirming the possibility of a vaccine tie to autism. The CDC official acknowledged to me that the information would be worthwhile. I asked whether CDC would attempt such a survey.
Such a survey wouldn’t necessarily cost a penny because the CDC already conducts regular telephone and mail surveys to monitor childhood immunization coverage. It could just add a question: has your child been diagnosed with an autism spectrum disorder?
While not necessarily conclusive, if the incidence of autism, Attention Deficit Disorder and other related disorders is roughly the same in the unvaccinated population as in the fully vaccinated, it might steer attention and research in a different direction. That would serve the interests of those who wish to debunk a vaccine-autism link….
The CDC official answered my question as to whether it would attempt a survey by saying that it was something that “somebody” should do.
“Why not the CDC?” I asked. “And, if not, then will the CDC encourage such a study?”
“Somebody should do it,” she said again, noncommittally.
To date, hasn’t been done. Or if it has, the CDC hasn’t publicized the results.
Is it the Dachel genes or the McElroy genes that gave our son autism?…We may never know………………………………………..
Researchers compared about 3,000 people in Sweden with and without autism and found that about 52 percent of autism was linked to common gene variants and rare inherited variations. Spontaneous genetic mutations accounted for only 2.6 percent of autism risk.
The investigators also found that genetics seem to play a stronger role in autism risk than environmental factors, according to the study funded by the U.S. National Institutes of Health.
The study, which the researchers said was the largest of its kind to date, was published in the July 20 issue of the journal Nature Genetics.
“From this study, we can see that genetics plays a major role in the development of autism compared to environmental risk factors, making autism more like height than we thought — many small risk factors add up, each pushing a person further out on the spectrum,” co-lead investigator Kathryn Roeder, professor of statistics and computational biology at Carnegie Mellon University in Pittsburgh, said in a university news release…..
According to NIMH Director Dr. Thomas Insel, “Knowing the nature of the genetic risk will help focus the search for clues to the molecular roots of the disorder. Common variation may be more important than we thought,” he said in the Carnegie Mellon news release.
Buxbaum explained that “within a given family, the mutations could be a critical determinant that leads to the manifestation of [autism] in a particular family member.”
He concluded: “The family may have common variation that puts it at risk, but if there is also a [new] mutation on top of that, it could push an individual over the edge. So for many families, the interplay between common and spontaneous genetic factors could be the underlying
At least 60 percent of autism is genetically inherited through gene mutations. Fifty-two percent of the mutations that cause autism are directly inherited from parents and family. These are the conclusions of the largest genetic study of the source of autism ever conducted. The research was led by Carnegie Mellon University’s Kathryn Roeder and was reported in the July 20, 2014, edition of the journal Nature Genetics.
The source of autism in children is in majority the result of the desire of parents with defective genes to have children. The study included the contribution of environmental causes of autism and found that genetics trumps any environmental cause for autism. The study was based on the genetic analysis of over 1.6 million Swedish families and compared 3,000 people with autism with a group that did not have autism that was the same size….
This discovery that included the National Institutes of Health in the United States and several experts from U. S. universities brings into serious doubt previous claims that vaccinations or any environmental source caused autism. The 2010 U. S. Court ruling that the use of thimerosal in vaccines was a cause of autism is now suspect of being invalid. Likewise the books that claim vaccinations caused autism are now considered to be less than factual.
We’re back to the “refrigerator mom” being blamed for autism–”parents with defective genes” is the updated version of blame the parents. This explains “at least 60 percent of autism,” according to this study. And the other 40 percent is likely due to all those other associations: fat moms, old moms, drinking moms, moms on anti-depressant, moms who have babies too close together, and moms who live too close to freeways. This lets thimerosal and pesticides off the hook. AND HOW TIMELY! With Robert Kennedy’s new book just out–it’s the perfect response. Kennedy can’t be right–THE LATEST SCIENCE SAYS SO!
