Genes

Studies of Rett syndrome hint at genes, cells and brain circuits that may be involved in autism — and may pave the way to treatments for both conditions.

A new autism mouse model carries the same mutation in a gene called ADNP that is seen in autistic people.

Researchers have identified mutations within regulatory regions that are likely to contribute to autism, using a speedy system of DNA ‘barcodes.’

Exposure to infection in utero may speed up the expression of many genes linked to autism — and hasten changes in brain anatomy.

Deleting an autism gene called TRIO derails neurons’ journey to their destination.

Mouse models of two genetic conditions related to autism show abnormalities in their movement patterns.

Injecting cells called interneurons into the brains of a mouse model of autism restores typical social behavior. But the reason for this effect is a puzzle.

Injecting the gene-editing tool CRISPR into the brains of mice may reverse the effects of an autism mutation at any age.

Neurons derived from autistic people with enlarged brains show extensive damage to long genes.
