Genetic studies find dysregulation in pathways that govern development of the prefrontal cortex in young patients with autism A study led by Eric Courchesne, PhD, director of the Autism Center of Excellence at the University of California, San Diego School of Medicine has, for the first time, identified in young autism patients genetic mechanisms involved in abnormal early brain development and overgrowth that occurs in the disorder. The findings suggest novel genetic and molecular targets...

Early disruptions in serotonin signaling in the brain may contribute to autism spectrum disorder (ASD), and other "enduring effects on behavior," Vanderbilt University researchers report. Serotonin is a brain chemical that carries signals across the synapse, or gap between nerve cells. The supply of serotonin is regulated by the serotonin transporter (SERT). In 2005, a team of Vanderbilt researchers led by Randy Blakely and James Sutcliffe identified rare genetic variations in children...

Sanford-Burnham researchers discover the molecular basis of autistic symptoms in children with a rare bone disorder -- findings that also provide new insights for the general autistic population Children with multiple hereditary exostoses (MHE), an inherited genetic disease, suffer from multiple growths on their bones that cause pain and disfigurement. But beyond the physical symptoms of this condition, some parents have long observed that their children with MHE also experience...

UCLA scientists identify 2,000 important genes Can the song of a small bird provide valuable insights into human stuttering and speech-related disorders and conditions, including autism and stroke? New research by UCLA life scientists and colleagues provides reason for optimism. The scientists discovered that some 2,000 genes in a region of the male zebra finch's brain known as "Area X" are significantly linked to singing. More than 1,500 genes in this region, a critical part of the...

Reports new study in Biological Psychiatry Impaired social function is a cardinal symptom of autism spectrum disorders (ASDs). One of the brain circuits that enable us to relate to other people is the "mirror neuron" system. This brain circuit is activated when we watch other people, and allows our brains to represent the actions of others, influencing our ability to learn new tasks and to understand the intentions and experiences of other people. This mirror neuron system is impaired...

A major register study from Karolinska Institutet shows that children born to certain groups of immigrants had an increased risk of developing autism with intellectual disability. The study includes all children in Stockholm County from 2001 to 2007, and brings the question of the heredity of autism to the fore. "This is an intriguing discovery, in which we can see strong links between a certain kind of autism and the time of the mother's immigration to Sweden," says principal investigator...

Research by Autism Speaks-Funded Infant Brain Imaging Study Offers Future Promise to Identify Infants at Risk for Autism before Behavioral Symptoms Become Evident The changes in brain development that underlie autism spectrum disorder (ASD) may be detectable in children as young as 6 months, according to research reported online today in the American Journal of Psychiatry. While core behaviors associated with ASD (impaired social communication and repetitive behaviors) tend to be...

A new study combines genetic and neurobiological approaches to confirm that synaptic mutations increase the risk of autism spectrum disorders (ASDs) A new study combines genetic and neurobiological approaches to confirm that synaptic mutations increase the risk of autism spectrum disorders (ASDs). It also highlights a role for modifier genes in these disorders. Published in PLoS Genetics, this research was conducted by researchers at the Institut Pasteur, the Paris Diderot University, the...

Autism Chances Enhanced With Low Birth Weight

The basis of autism spectrum disorder (ASD) is long known to have a strong genetic component, however new research is suggesting that environmental factors may play an equally important role in this developmental disorder affecting nearly one in 100 children. The study, published in the journal Psychological Medicine suggests that low birth weight is an important environmental factor contributing to the risk of ASD, reports Wendy Leopold for Northwestern University. Lead author of the...
