Protein aggregates gum up ‘master regulator’ of autism-linked genes

The regulator, CPEB4, typically controls protein production for hundreds of autism-linked genes, but an alternative version of it found in autistic people forms irreversible clumps and malfunctions.

UBE3A’s link to synaptic pruning bolstered by fly study

Increasing or reducing the levels of the UBE3A gene, which is associated with autism and autism-related syndromes, results in altered patterns of synaptic pruning — a process that snips away brain cell connections.
