Autism-linked perturbations converge on cell skeleton and RNA-binding proteins
The findings solidify the idea that autism-linked mutations affect brain activity by way of several key shared mechanisms.

Head size parts autism into two major subtypes
An imbalance in the number of excitatory neurons in early brain development may account for the difference.

Autism-related genes converge on microglia and dopamine in zebrafish
The findings add to the growing evidence that genes with disparate functions can play similar roles in brain development.

Rare autism-linked mutation starves growing neurons of essential nutrients
The mutation prevents certain amino acids from entering neurons, causing the cells to die early in development.
