Gene-activity map of developing brain reveals new clues about autism’s sex bias

Boys and girls may be vulnerable to different genetic changes, which could help explain why the condition is more common in boys despite linked variants appearing more often in girls.

New tool may help untangle downstream effects of autism-linked genes

The statistical approach helps scientists better control for both measured and unmeasured confounders in gene-expression data, revealing causal relationships between autism-linked genetic variants and downstream cellular effects, such as impaired neuron development.

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.
