Autism’s ties to the cell skeleton
Many genes related to the condition play a role in the internal scaffolding of cells, and cytoskeletal disruptions can affect neurodevelopment and behavior.

Chromatin remodeling tied to altered splicing in autism model
Exposing neurons to valproic acid, a well-known environmental risk factor for autism, disrupts their ability to generate different proteins from the same gene.

‘Double duty’ autism-linked genes upend conventional characterizations
What these genes do and how they affect autism depends on when in development they’re studied, despite what classic ‘gene ontology’ analyses say.
