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.

Mutation in top autism-linked gene may alter eye reflex

The discovery could help clinicians diagnose children who carry mutations in the gene, called SCN2A, and gauge their responses to potential therapies.

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.

Accepting “the bitter lesson” and embracing the brain’s complexity

To gain insight into complex neural data, we must move toward a data-driven regime, training large models on vast amounts of information. We asked nine experts on computational neuroscience and neural data analysis to weigh in.
