Of nine genetic models examined in a new study, all had some incidence of cardiac abnormalities. But the problems varied widely depending on the affected genes.

Scientists have at last filled in the missing gaps — an advance likely to inform every aspect of autism genetics research, Eichler says.

Some copy number variants may boost a person’s chances of having autism, but to a lesser extent than previously thought.

Over the past century, scientists have used a variety of animal models to advance their understanding of the developing brain and autism.

Inhibiting a protein that helps cells move or change shape prevents atypical neuronal migration in 3D clusters of brain cells carrying autism-linked genetic variants.

The finding that MDMA and an experimental serotonin agonist increase sociability across six different model mice suggests that disparate autism-linked mutations converge on the same underlying pathways.

An autism-linked mutation could make the brain grow unusually large by prompting cells to express a chemical signal better known for its connection to cancer.

The investigational drug arbaclofen may right an imbalance between inhibitory and excitatory signaling in the animals’ brains.

Mutations in CUL3, a gene strongly linked to autism, may cause differences in brain structure by disrupting cytoskeleton proteins, according to a new study.

Mice missing a copy of chromosomal region 16p11.2 are slow to learn motor tasks and have dysfunction in a brain circuit associated with stress and movement, according to a new study. Normalizing this circuit’s activity corrects the learning deficit.
