Genes

Researchers have used the gene-editing tool CRISPR to disable the MECP2 gene in marmoset embryos. The six such marmosets created seem to recapitulate aspects of Rett syndrome.

Researchers have used a new gene-editing technique to delete a segment of DNA associated with autism and schizophrenia from mouse brain cells.

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.

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

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.

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.
