Proteins associated with autism mediate the growth of spiny neuronal projections, called dendrites, that form brain circuits in early life, according to unpublished research presented today at the Society for Neuroscience meeting.

Rare or common, inherited or spontaneous, mutations form the core of autism risk.
Interested more in ideas than in dominating a crowded field, Michael Wigler decided to apply his expertise in cancer genetics to studying poorly understood features of autism.
A team of British researchers has garnered some of the first genetic evidence supporting their theory that sex hormones play a role in the development of autism.
Studying the relatively well-defined genetics of Williams syndrome may help unravel the poorly understood genetic and neurobiological roots of autism, researchers say.
Several new genetic variants associated with schizophrenia lie in regions important for immune function and associated with autism. This suggests that both disorders stem partly from abnormal activation of the immune system, say some researchers.
The brains of people with autism have structural abnormalities that disrupt normal connections between brain regions and impede the flow of information across the brain. That’s the conclusion of a 20-year-old theory supported by several new studies.
A common variant of a gene called CACNA1G — which makes a channel that helps regulate calcium flow between cells — may increase the risk of developing autism, according to research published in Molecular Psychiatry.
Applying an emerging technique that combines genetic data and brain scans, researchers have identified two new genes involved in schizophrenia. The method, called ‘imaging genetics’, holds promise for linking genes to brain function in complex psychiatric disorders, including autism.
The answer to a long-standing mystery in visual neuroscience may also help explain how people with autism perceive faces, according to a study published in March in the Proceedings of the National Academy of Sciences.
