Autism with intellectual disability is less heritable than autism alone, according to a new study of how the conditions run in extended families.

A gene-editing treatment shows long-lasting effects in a mouse model of Angelman syndrome, a genetic condition related to autism.

All five participants in a clinical trial of a gene therapy for Angelman syndrome experienced leg weakness, leading sponsors to pause the study.

The first genetic analysis of multiple types of variants from people with autism or other neurodevelopmental conditions reveals hundreds of genes that may be linked to neurodevelopment.

An analysis of four molecular datasets shows a distinct signature, including changes in gene expression and chemical DNA modifications, in some autism brains.

Genome sequences from a research cohort of autistic African children and their families have revealed more than 4 million novel variants, some of which occur in genes not previously linked to the condition.

Most of the large, spontaneous genetic mutations tied to autism are passed down from fathers. But, unlike with smaller mutations, a parent’s age is unlikely to up the rate at which they occur.

People with particularly low levels of FMRP, the protein lacking in those with fragile X syndrome, are more likely to also have autism and severe intellectual disability.

An atlas that details gene expression in neurons and other cells from the intestines of mice and people may help to elucidate the link between gut problems and autism.
