An unusual brain response to sound may distinguish children with mutations in SCN2A, a leading candidate gene for autism.

Male rats missing an autism candidate gene called SHANK3 spend less time sniffing, nuzzling and chasing their peers than controls do.
Children with mutations in a gene called DYRK1A, a leading autism candidate, have a distinct set of features, including intellectual disability, speech delay, motor problems and a small head.
Children with autism inherit a greater burden of common genetic variants associated with autism than would be expected by chance. These variants combine with rare, spontaneous mutations to boost autism risk.
Infant siblings of children with autism who also have the condition show motor problems into their second year.
Autism traits may become more apparent as girls reach adolescence but stay stable in boys.
A brain circuit that controls movement is altered in people with autism, a postmortem brain study suggests.
Children with autism who are highly anxious tend to move their heads during brain scans and so may be excluded from important studies.
The activity of a set of proteins in the blood may distinguish people with autism from those without the condition.
Bundles of nerve fibers that bridge brain areas develop rapidly during the first six months of life. Fibers that connect language regions mature more slowly than those linking motor regions.
