Research Study Findings

 

General Research

New method vets quality of antibodies for experimental use~ Researchers have devised a reliable technique for evaluating how well antibodies home in on specific molecules in scientific experiments. The new approach, published 29 June in Nature Methods, could take some of the guesswork out of studies that use these sticky immune molecules to flag proteins of interest1.Autism researchers use antibodies to determine the binding partners of proteins associated with the disorder.

Study finds link between autism and labour induction ~video~ Duke University's Simon Gregory looks at a study that suggests a link between induced or augmented pregnancy and the risk of autism. August 12,2013

Autism’s surprising link to cancer gene ~Researchers studying two seemingly unrelated conditions autism and cancer have unexpectedly converged on a surprising discovery. Some people with autism have mutated cancer or tumour genes that apparently caused their brain disorder. Aug. 11 2013

Across Generations: Older Fathers May Transmit Autism Risk To Their Grandkids~ Last year, several studies came out showing that the age of the parents, and particularly the age of the father, seemed to increase a child’s risk for autism. Now, it seems that on top of the father’s age (or mother’s), it’s also the grandfather’s age at the time he conceived his child that can affect his grandchild’s risk of autism. March 20, 2013

    Low birthweight infants have five times rate of autism ~ The children, some

    born as small as about a pound, were followed for 21 years making this study,

    published in the prestigious journal Pediatrics, one of the most remarkable of

    its kind. The infants were born between September 1984 through July 1987 in Middlesex, Monmouth, and Ocean counties in New Jersey at birthweights from

    500 to 2000 grams or a maximum of about 4.4 pounds.

Summary of "Mitochondrial Dysfunction in Autism" Jan 2011 teleconference~ What were the results of this study?Children with autism were found to have several abnormalities in mitochondrial function, when compared to the neuro-typical control group, suggesting there may be a high rate of mitochondrial dysfunction, mtDNA overreplication and mtDNA deletions in children with ASD.  In fact, 8 out of 10, or 80% of children in the ASD group were found to have mitochondrial and biochemical abnormalities of one kind or another.

   New Findings Validate the Accuracy of Autism Diagnosis in Children With 

   Down Syndrome ~  New findings from a 16-year study confirm that the  

   Diagnostic and Statistic Manual of Mental Disorders (DSM), the gold-standard  

   for the classification of mental health conditions, can be used to accurately

   identify autism spectrum disorders (ASD) in children with Down syndrome,

   according to research from Kennedy Krieger Institute.~ October 2011

   Autism Research:Breakthrough Discovery on the Causes of Autism

    researchers at the University of California, Davis called "Mitochondrial

    Dysfunctionin Autism  (i) discovered a profound and serious biological

    underpinning of autism-an acquired loss of the ability to produce energy in the

    cells, damage to mitochondria (the energy factories in your cells), an increase

    in oxidative stress(the same chemical reaction that causes cars to rust,apples turning brown,fat to become rancid,skin to wrinkle).~ December 2010

   Genes implicated in twins' autism - baltimoresun.com ~Autism could have

    100 different causes," says Kennedy Krieger neuroscientist Jonathan Pevsner,

     who's encouraged by DNA sequencing studies of autistic patients' genomes.

Genetic and Enviromental

Maternal factors, birth order up autism risk SFARI.org - Simons Foundation Autism Research Initiative ~ Having one child with autism raises the odds of having a second child with the disorder 20-fold, according to one of the largest epidemiological studies so far to address the inheritance of autism risk . In families that have one child with autism, the next-born child has the highest risk of developing the disorder. This risk is higher for brothers than for sisters, and if the first child with autism is female.

 

Enviromental

Is Autism Caused By The Environment? Just As Much As Genes, Scientists Say-Autism’s 'Surprising' Link To The Environment May 2014~The role of the environment in autism is “a crucial area of study,” especially since the increasing prevalence of the disorder in recent decades has left many scientists wondering what's behind the rising numbers. A new study the largest one to date examined how autism runs in families, and found that environmental factors are far more important in understanding autism causes than previously thought. Researchers at King’s College London, the Karolinska Institutet in Sweden, and Mount Sinai in the U.S. reviewed data from Swedish national health registers, analyzing two million people 14,516 of which had been diagnosed with autism. The researchers examined two measures of autism risk, heritability (risk attributed to genetic factors) and “relative recurrent risk,” or risks among people who have a relative with autism.

 

Genetic Research

Research Team Identifies 33 Genes That Contribute to Autism Risk~ June 24, 2015 -Published today in Nature, the study examined data on several types of rare, genetic differences in more than 14,000 DNA samples from parents, affected children and unrelated individuals. It is the largest sample to date, and provides evidence that small differences in some of possibly 1,000 risk genes contribute to autism. In addition to increasing the number of definitive autism genes almost fourfold, the team pinpointed more than 70 other likely ASD genes.

Mapping the genes for autism: Canadian study part of a worldwide effort~ Is autism a genetically inherited disorder? If so, which gene or genes are responsible? More than 1,200 families from all over the world, including 200 families across Canada, are participating in this global research collaboration, the largest ever assembled to locate the genes associated with autism spectrum disorders. Locating the genes will be no easy task.There are approximately 30,000 genes in the 23 chromosomes that make up the human genome.Roughly 4,000 of these genes are located in the brain.Autism is known as a complex disorder that is believed to involve many genes on several chromosomes. Preliminary findings have zeroed in on Chromosome 7 as one hot spot for continued research. But while results are promising, there remains much work to be done.Researchers hope eventually to enable clinicians to biologically diagnose autism, allowing children to be diagnosed earlier than ever and leading to more effective treatments and better outcomes for them and their families.Knowing what causes autism may even allow us, one day, to prevent it.

Common Genetic Ground Found for Depression, Schizophrenia, Autism~ Mental illnesses like depression and schizophrenia clearly run in families, but neuroscientists have always assumed that the biological drivers behind these disorders were distinct. However, expanding on results reported earlier this year from psychiatry’s largest ever experiment, researchers now report that known genetic variations account for 17% to 29% of the risk for schizophrenia, depression, bipolar disorder, autism and attention-deficit/hyperactivity disorder (ADHD). And risk for one condition is often strongly linked with risk for others. August 12, 2013

More genes linked to autism with advanced sequencing tool~A Canadian-led international research team has identified several new genetic mutations that appear to be linked to autism spectrum disorder, using a method that looks at the entire DNA code of affected individuals.The method is called whole genome sequencing,and the researchers believe they are the first to use it to take an in-depth look at genetic alterations associated with autism spectrum disorder, or ASD. ~July 11, 2013

Scientists find gene pattern in autism patients ~Scientists have identified a genetic pattern common to people with autism that is linked to the way messages are sent in the brain.Medical Research Council researchers at the University of Oxford said the knowledge could help them understand the role that genetics plays in autism. Doctors can currently only identify the exact genetic cause of autism in about one in five cases but it is known that genes play an important role in the development of autism spectrum disorders, an MRC spokeswoman said. June 7, 2013

Genetic Research on Autism Advances ~In the current project,researchers tested the contribution of rare genetic mutations, as well genetic variations common to autism,to see whether these different types of genetic risk factors are related.Instead of testing individual genes, the researchers chose to study gene collections, in an attempt to understand general pathways involved in autism. May 2, 2012

    Israeli and NY researchers find evidence autism genetic ~ A team at Cold  

    Spring Harbor Laboratory (CSHL) in New York, led by an Israeli doing

    postdoctoral fellowship work on mice, has for the first time provided

    functional evidence that inheriting fewer copies of genes on chromosome

    #16 leads to autism-like features.  ~ Oct 2011

Vaccine Research

    Medical fraud revealed in discredited vaccine-autism study ~ In 2004,

    Brian Deer of The Sunday Times published damning evidence about Dr.

    Wakefield’s ties to the lawsuit, showing that the children in the study were

    recruited unethically, and exposing other flaws in the published study.  

   ~January 2011

  Autism-vaccine study retracted ~A medical journal in Britain has retracted

    a controversial study about the MMR it published in 1998 that linked the use of

    a vaccine in children to autism. ~  February 2010

   Vaccines cause autism: Supporting evidence ~ Rates of autism have

    skyrocketed 1000% since 1990, yet defenders of vaccines and the

    pharmaceutical industry keep scratching their heads in confusion: What could

    be causing this? Lots of clues point to vaccines as one of the primary

    contributing factors to increased rates of autism.~ October 2009

Brain Research

Lab-spun spheres reveal common biology in boys with autism ~July, 2015. Balls of neurons derived from the skin cells of four boys with autism show shared alterations in biology and gene expression, researchers report today in Cell1. Like many people with autism, none of the four boys have a mutation known to be associated with the disorder.

10-week reading intervention improves brain activity in autistic children~ Ten weeks of intensive reading intervention for children with autism spectrum disorder was enough to strengthen the activity of loosely connected areas of their brains that work together to comprehend reading, University of Alabama at Birmingham researchers have found. At the same time, the reading comprehension of those 13 children, whose average age was 10.9 years, also improved.
