Gene Mutations and Autism Risk: A Link?

  • 2 of 2

In other words, diagnosing autism retains an element of subjectivity. The still-changing and evolving criteria for autism add to the challenge and, too, the confusion. Researchers have been hopeful that genetic studies might point to a possible biomarker for autism.

Jonathan Sebat, a professor of psychiatry and cellular and molecular medicine at the University of California, San Diego who was not involved in the three new studies, describes the studies not as a “breakthrough, because we knew this was coming” but as a “turning point.” Sebat said that “in the next year or two” we can likely expect to find “20, 30, maybe more such mutations.”

Like previous genetic studies about autism, the new studies have found rare genetic mutations in only a very few individuals vs. some “autism gene” in many individuals. Developing therapies from the new studies’ findings is a long way off. What the new studies, and future studies like them, may end up telling us is that “what is known generally as autism may represent a broad category of related but biologically distinct conditions.” Finding a biomarker that would definitely say “this child is autistic” remains elusive.

Since the terms 'autism', 'autism spectrum disorder' and 'asperger's syndrome' were all created by one field, Psychiatry, here is what the Chairman of the Task Force of the current DSM 4 (the book of 374 'mental disorders' including the above 3) says about the 'epidemic of autism':

"DSM 4 gave autism purchase by introducing a milder form that is close to the extremely populous boundary of normality. Then autism took flight on the wings of definitional diffusion, internet contagion, financial incentive, and naïve interpretation of epidemiological results.
The autism “epidemic” is set to spread further starting in May 2013, when the next revision of the diagnostic manual (DSM 5) will be published. The DSM 5 definition of an “autistic spectrum” will cast an even wider net, capturing many people now considered to be normal or to have another disorder" Dr. Allen Frances, professor emeritus of Psychiatry

Here is what another professor emeritus of Psychiatry says:
"We don't have an epidemic of mental illness, we have an epidemic of psychiatry." Dr. Thomas Szasz

"It couldn't POSSIBLY be the
WATER filled with amoeba, parasites, DRUGS, bird and animal FECES, DEAD ANIMALS
,PESTICIDES, antibiotics and every manner of unidentifiable crap! " - Jane B.

Well, we can immediately rule out amoeba[s], parasites, bird and animal FECES, DEAD ANIMALS, as that pretty much describes the water supplies of European cities up until modern water purification systems were put in place.

And, Barbara G., you have to realize all our food, no matter what the source, contains genes, including whatever bacteria may have been on and in the food at the time of eating. According to you, we acquire behaviors of other species simply by eating their genes. So, if you eat salmon, you'll feel like swimming, eat chicken, you'll be doing the chicken dance soon ! If you eat eggplant, well, let's just say that'll make you as happy as one, according to your theory.

Jane B. you are right but you forgot to mention the foods we are eating that are genetically engineered with genes from the lower orders of life and the adjuvants and mediums that vaccines are grown in. One mother mentioned that her son likes to hang over the couch, another that her child constantly flaps his hands. These behaviors belong to and are the intrinsic imprinting of certain orders of life. My heart aches for these children and their parents who are part of the great unfettered genetic experiment with food.

I think autism and exspecally asperger is a gift: we are high intelligent humans, and I want to stay how I am. I will not get normal, I hate to get normal. I dont understand why asperger and autism-humans are not allowes to get children.i dont understand, why the aspergers´and autistic´children have to raise up like "normal" children...Without aspies and autis there would be no electric light, no higher mathematic, no moon landing, no computers,no higher physics--this is has been all done by us: the aspies and high autistic humans. I want equal rights and no racism which prefers non-autistic/non-aspergers´ normal people to us, who are said to be "ill". We are not ill. We dont talk with people which thing themselves to be sane and tell us to be insane. We are not insane, we have a high IQ. But often we are not allowed to use it. Most people want us to talk about the weather at overcrowded sandwichbars and loud music--a "social event" to make "small talk" by staring each other in the eyes? Why no "big talk" on "big, social meatings"?----But photographing and collecting clouds in this way is insane, but always silly talk about the weather (often without to know how weather works)is sane? Higher intelligence is not a disease! I love it to be autistic!The increase has to do with the change of the autistic people themselves: We use computers, We know about our rights. We know we are humans with the human rights .We are many. We are intelligent, some extremly in ma

The increase has to do with the change of the autistic people themselves: We use computers, We know about our rights. We know we are humans with the human rights .We are many. We are intelligent, some extremly in mathematics and poorly in language. We marry. We get children and are proud of them. We dont need the acceptance of non-autistic people any more. We accept ourselves how we are. We are strong,, we get our children, we get our children back some day. We are friendly, we love peace, but we are more intelligent in a special way. And we fight for our freedom in all situations of life...

Come on, everybody has been eating PINK SLIME, BLEACH, COWS THAT ARE FED CHICKEN MANURE, ANTIBIOTICS, PESTICIDES AND EVERY MANNER OF CONTAMINANT and you "WONDER" what could be the CAUSE? Duhhh, it's the FOOD! So, did you think eating heavy metals, pesticides, bleach and dog food wouldn't come back to bite you in the butt? So, you thought a diet of lard, tallow, corn syrup, and junk food mixed with poison would be GOOD for you? This is as laughable as Newt's imaginary moon colony. Let's have "doctors" keep "searching" for a "cause". It couldn't POSSIBLY be the
WATER filled with amoeba, parasites, DRUGS, bird and animal FECES, DEAD ANIMALS,
PESTICIDES, antibiotics and every manner of unidentifiable crap! Please, I give it about
2 more years and EVERYBODY will be born autistic.

I think until it's fully understood what autism actually is , the debate on what causes it has to be viewed with caution. There are a lot of children being diagnosed now who previously would have been written off as 'just a bit slow' and children are being diagnosed much earlier. I wasn't diagnosed as severly dyspraxic/dyslexic and dyscalculic until last year (aged 33) but I was in special needs classes through out school having been told at various points that I was thick/lazy/stupid...(A high point was one teacher telling me he was consistently surprised I could walk and breathe at the same time)
Consider also that the impact of the discussion on the idea that the triple vaccine caused autism may not be seen for some time as there were many parents in this country (the UK) who chose not to vacciate their children ; dispite it later emerging that the scientist in question falsified his results there are still parents who won't vaccinate and this may result in a rise in measles etc along with the accompanying problems.
As someone who has an autistic child, I would also like to point out that parents make the best decisions for their children that they can and they need to be supported in that because I saw an awful lot of parents tear themselves apart because they had vaccinated their child and that child later developed autism .

We have expanded the criteria we use for designating someone on the autism spectrum. That is likely the single biggest "cause" of autism "increase". It's a matter of perception. If someone is obsessive, does that necessarily mean they're on the autism spectrum? By THAT criteria, most scientists, musicians, engineers or anyone dedicated to doing something well would so qualify.

I would be more inclined to blame the rise in world back ground ionizing radiation from nuclear testing in the 1940s thru today. Between 1950 and 1980 we set off nearly 450 nucs, which raised the world back ground radiation by a factor of about ten. That's not enough to be lethal but it might be enough to induce more such de novo mutations. On the other hand,,,maybe not...
