(Ivanhoe Newswire) — Autism is one of the most common genetic alterations, caused by a deletion of the 27-gene cluster on chromosome 16. By generating mouse models of autism, scientists at Cold Spring Harbor Laboratory (CSHL) provided the first evidence that inheriting fewer copies of these genes leads to features resembling those used to diagnose children with autism. "Children normally inherit one copy of a gene from each parent. We had the tools to see whether copy number changes...

[ Watch the Video ] Models of autism show that gene copy number controls brain structure and behavior Scientists at Cold Spring Harbor Laboratory (CSHL) have discovered that one of the most common genetic alterations in autism -- deletion of a 27-gene cluster on chromosome 16 -- causes autism-like features. By generating mouse models of autism using a technique known as chromosome engineering, CSHL Professor Alea Mills and colleagues provide the first functional evidence that inheriting...

By Alicia Rose DelGallo, Ivanhoe Health Correspondent (Ivanhoe Newswire) -- Mice with a single defective gene are showing striking parallels to humans with autism. According to a study published in the September 30th issue of Cell, a Cell Press publication, the mouse model offers several promising discoveries. The study involved developing mice lacking CNTNAP2, a rare variant of the gene that has been shown to cause a form of autism known as cortical dysplasia-focal epilepsy syndrome...

Mice with a defective version of a single gene show behaviors and symptoms that are remarkably similar to characteristics observed in humans with autism spectrum disorders. The animals also respond similarly to an FDA-approved drug used to treat repetitive behaviors in people with autism. According to researchers who report their findings in the September 30th issue of Cell, a Cell Press publication, the mouse model offers a window into the biological mechanisms that underlie the disease...

These changes may also affect the mix of bacteria present in the digestive tract Researchers at the Center for Infection and Immunity (CII) at Columbia University's Mailman School of Public Health and at the Harvard Medical School report that children with autism and gastrointestinal disturbances have altered expression of genes involved in digestion. These variations may contribute to changes in the types of bacteria in their intestines. Full study findings are reported online in the...

The first transgenic mouse model of a rare and severe type of autism called Timothy Syndrome is improving the scientific understanding of autism spectrum disorder in general and may help researchers design more targeted interventions and treatments. The research is described in a paper published last week by scientists at the University at Buffalo and Stanford University in the Proceedings of the National Academy of Sciences. The transgenic mouse developed at UB exhibits the repetitive...

Researchers at the Stanford University School of Medicine and Lucile Packard Children's Hospital have used a novel method for analyzing brain-scan data to distinguish children with autism from typically developing children. Their discovery reveals that the gray matter in a network of brain regions known to affect social communication and self-related thoughts has a distinct organization in people with autism. The findings will be published online Sept. 2 in Biological Psychiatry. While...

The biological causes of autism are still not understood. A diagnosis of autism is only possible after ages three or four; and the tests are subjective, based on behavioral symptoms. Now, in research that appeared in Neuron, scientists at the Weizmann Institute of Science, Carnegie Mellon University and the University of California, San Diego have found, for the first time, a method that can accurately identify a biological sign of autism in very young toddlers. By scanning the brain activity...

Research provides opportunity for identifying genes linked to autism Siblings of people with autism show a similar pattern of brain activity to that seen in people with autism when looking at emotional facial expressions. The University of Cambridge researchers identified the reduced activity in a part of the brain associated with empathy and argue it may be a 'biomarker' for a familial risk of autism. Dr Michael Spencer, who led the study from the University's Autism Research Centre, said:...

Researchers at the Harvard School of Public Health reported on Monday that they have identified a number of perinatal and neonatal conditions that may be linked to autism, although the evidence is still too scarce to point to specific culprits, they said. Autism refers to a group of developmental brain disorders that obstruct a person's ability to communicate and interact socially.  The condition ranges from severe cases of "classic" autism to mild forms like Asperger's syndrome. The...
