Genes involved in the formation of myelin, a fatty substance that sheathes neurons, are altered in autistic people and in several mouse models.

Rare mutations in a gene called BAZ2B are associated with various conditions of brain development, including autism.

Researchers have monitored the active genome in brain organoids over the course of nearly two years — and may find clues to autism’s roots.

Autism may stem from a different — and larger — set of genetic mutations in women than it does in men.

This year’s top papers deepen our understanding of autism’s genetics and reveal mixed results from trials of autism therapies.

A shortage of CUL3, a leading autism gene, may impair social behavior in mice by ramping up protein production in neurons.

A new technique uses ultrasound instead of light to detect gene expression in cells.

A new technique allows researchers to transplant human microglia into mouse brains and better study the association between these cells and autism.

A new method scans gene expression in live cells and could help scientists study autism genes.

Researchers have identified a distinctive pattern of gene expression in the white blood cells of young autistic boys.
