Autism And Genes, More Compelling Evidence Of Links
Three new genome-wide association studies bring together the most compelling evidence to date that genes and autism are linked.The studies scanned and compared the entire set of human DNA of people who have an autism spectrum disorder (ASD) with that of people who do not and found small genetic differences that affect the way brain cells link up to make the circuitry of a child’s brain.29 Apr 2009

Risk Of Autism Tied To Genes That Influence Brain Cell Connections
In three studies, including the most comprehensive study of autism genetics to date, investigators funded in part by the National Institutes of Health have identified common and rare genetic factors that affect the risk of autism spectrum disorders.29 Apr 2009

Autism Genes Discovered; Help Shape Connections Among Brain Cells
A research team has connected more of the intricate pieces of the autism puzzle, with two studies that identify genes with important contributions to the disorder. One study pinpoints a gene region that may account for as many as 15 percent of autism cases, while another study identifies missing or duplicated stretches of DNA along two crucial gene pathways.29 Apr 2009

First Neuroimaging Study Examining Motor Execution In Children With Autism Reveals Brain Activation Differences
In the first neuroimaging study to examine motor execution in children with autism, researchers at the Kennedy Krieger Institute have uncovered important new insight into the neurological basis of autism.29 Apr 2009

Researchers Demonstrate First Common Genetic Risk Factors For Autism
Researchers have made an important step forward in understanding the complex genetic structure of autism spectrum disorders. A researcher collaboration, including geneticists from the University of Pennsylvania School of Medicine and The Children’s Hospital of Philadelphia (CHOP), have detected variations along a genetic pathway that is responsible for neurological development, learning and memory, which appears to play a significant role in the genetic risk of autism.29 Apr 2009
