Autism / Autism Spectrum Support Group
Autism is classified as a neurodevelopmental disorder which manifests itself in markedly abnormal social interaction, communication ability, patterns of interests, and patterns of behavior. Although the specific etiology of autism is unknown, many researchers suspect that autism results from genetically mediated vulnerabilities to environmental triggers.

I've skimmed part of her website and it reads like nonsense to me which is strange because my qualifications aren't actually that far off hers. She's not an MD as far as I can see but a microbiologist and immunologist.
I found this article.
in my opinion, these type of people who claim to cure autism usually can't. if autism was curable, it would be all over every credible news source and every doctor would be using it.
Problem is that usually these things are not examined by anyone with either the biochemical or medical knowledge to determine that it is a fraud - and then even harder explaining that to the authorities.
And of course most of these experts are busy doing proper work.
I could tell you something that would go beyond most people's knowledge and it would be really easy to be able to create a completely plausible lie to support some kind of scam cure.
It's complete bunk.
My understanding is that you give the child a solution that has RNA in it? If that's wrong please correct me.
Let's talk about some basic common sense. All animal and plant cells contain RNA. All.
It acts as a sort of middle man between DNA for protein synthesis. Think of DNA as being the master tapes and RNA as sort of copies to be used in the actual making of proteins.
Given RNA is in every plant and animal cell (plus many bacteria) you consume a fair amount of it every time you eat.
Unlike the RNA in your cells though this consumed RNA doesn't have any action. That is for two reasons - to have action the RNA needs to be within your cell - and intact RNA doesn't get to your cells because
a) RNA is unstable, it doesn't last long (it's constantly being made in cells and used up)
b) the mouth and stomach are full of enzymes that break up RNA (along with enzymes that break up proteins, fats etc).
While people say "you are what you eat" it isn't literally true. If I eat lettuce for the day you will find no trace of lettuce DNA or RNA if you do a cell analysis. The DNA and RNA simply doesn't survive to have any action other than to be chopped up into tiny bits and assimilated.
