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.

Is excess brain fluid an early marker of autism?
Brain scans of hundreds of infants suggest that up to 80 percent of those with autism have unusual amounts of cerebrospinal fluid. Researchers are studying how this might contribute to the condition.

‘Gain-of-function’ mutation spawns autism traits
The mutation increases the activity of an autism-linked protein and leads to social difficulties and other behavioral differences in mice.

Prenatal exposures; Angelman trial suspension; autistic adult well-being
This month’s issue of the Null and Noteworthy newsletter breaks down some negative results involving prenatal exposures, an experimental treatment for Angelman syndrome, and the role that age at autism diagnosis plays in subsequent outcomes, and more.

The future of autism therapies: A conversation with Lilia Iakoucheva and Derek Hong
If a therapy for autism’s core traits makes it to market, it will likely take one of three forms, the researchers say.

RNA therapy restores gene function in monkeys modeling Angelman syndrome
The result raises hopes for an ongoing clinical trial in people — and offers fresh insight into the biology of imprinting and the UBE3A antisense transcript.

Single gene insufficient to account for dup15q, Angelman traits
UBE3A, a key gene associated with both autism-linked conditions, can explain most — but not all — of the syndromes’ atypical neuronal properties.

Adult Angelman mice get some benefit from boosting UBE3A gene expression
The treatment eases the animals’ sleep troubles, suggesting it has clinically meaningful effects beyond what was thought to be a critical window in early life.
