(Ivanhoe Newswire) "“ The largest known study of twins with autism spectrum disorder (ASD) suggests that environmental influences and maternal infections during pregnancy may greatly increase risk for ASD. Environmental influences include parental age, low birth weight and multiple births. The study suggested that both genetic and shared environmental factors significantly increase risk for ASD: an estimated 38 percent of risk being associated with genetic heritability and 58 percent...

Non-inherited genetic factors also in the mix -- NIH-funded science The largest and most rigorous twin study of its kind to date has found that shared environment influences susceptibility to autism more than previously thought. The study, supported by the National Institutes of Health, found that shared environmental factors "“ experiences and exposures common to both twin individuals "“ accounted for 55 percent of strict autism and 58 percent of more broadly defined autism...

Genetics alone cannot account for the high rates of autism among fraternal, or non-identical, twins Autism Speaks, the world's largest autism science and advocacy organization, joined in announcing significant findings from the largest known study of twins with autism spectrum disorder (ASD). This work, conducted by a consortium of renowned researchers and using material from Autism Speaks Autism Genetic Resource Exchange (AGRE) was published online today in the Archives of General...

Environmental component may be substantial After evaluating twin pairs in which at least one child has autism or autism spectrum disorder (ASD), researchers suggest that the shared environment may play a more substantial role in development of the condition than shared genes do, according to a report published Online First today by Archives of General Psychiatry, one of the JAMA/Archives journals. Current estimates suggest that 40 of every 10,000 children have autism, and prevalence rates for...

Autism is often described as a spectrum "“ varying from severe syndromes in which the symptoms of autism are only part of the problem to the more classic autism characterized by impaired social skills, delayed language development, and repetitive or stereotyped behaviors. The genetic origin of the disorder may also occur along a spectrum. On one hand, a severe mutation affecting a particular gene gives rise to syndromic autism, a form of the disorder that occurs along with other...

Many roads can lead to the same place, often crossing over one another and sometimes passing the same landmarks. The interactome, or protein interaction network, for autism spectrum disorders developed by researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute at Texas Children's Hospital in collaboration with scientists at the Center for Cancer Systems Biology at Dana-Farber Cancer Institute demonstrates how protein pathways converge, diverge and...

(Ivanhoe Newswire) -- Yale researchers have discovered that hundreds of small genetic variations are associated with autism spectrum disorders. This new research supports the theory that autism is not caused by one or two major genetic defects but rather by many small variations. Investigators looked at more than 1,000 families that had a single child with autism, an unaffected sibling and unaffected parents. They compared individuals with autism to their siblings to determine the genetic...

A gene-sequencing study of children with autism, described in an advance online publication in Nature Genetics on 15 May, offers a sneak peek at a technique which, combined with other approaches, may explain 40 to 50 percent of the genetic causes of the disorder within just a few years, proposes the study's lead investigator. This approach, says Evan Eichler of the University of Washington in Seattle, will potentially allow clinicians to "lift the hood on what has gone wrong in each...

Researchers sequenced the protein-coding sections of the genomes of affected children and their parents to find mutations Scientists at the University of Washington (UW) Department of Genome Sciences have identified several sporadic or "de novo" genetic mutations in children with autism spectrum disorder. The researchers applied leading edge molecular biology techniques and massively parallel sequencing to simultaneously examine all of the protein coding portions of the genome, collectively...

By dividing individuals with autism spectrum disorders (ASD) into four subtypes according to similarity of symptoms and reanalyzing existing genome-wide genetic data on these individuals vs. controls, researchers at the George Washington University School of Medicine and Health Sciences have identified 18 novel and highly significant genetic markers for ASD. In addition, ten of the variants were associated with more than one ASD subtype, providing partial replication of these genetic markers....
