Large study underscores role of gene copy number in autism
People with autism tend to carry mutations that duplicate or delete several genes at once, according to a large study published 1 May in the American Journal of Human Genetics.

Brain atlas maps gene expression in three dimensions
Researchers have charted patterns of gene expression in a three-dimensional representation of the human brain. The results, published 20 September in Nature, show that different brain regions have distinct molecular and functional roles.

Defects in autism risk genes may lead to slower signals
Mutations in two genes linked to autism, neurexin and neuroligin, slow down neuronal signaling, according to research published 2 August in Science. Analyzing the mutations in the nematode Caenorhabditis elegans, the study found that mutations in these genes affect signaling in the opposite direction than is typical.
